Is Globalization Good or Bad Essay

Is globalisation Good or Bad EssayThrough the human beingswide interconnectedness among community, globalisation has been appe atomic number 18d. Globalization refers the integration of global economies, societies and husbandrys done the communication, back breaker and trade. During this period of this extremity, one question has been raised whether is globalization bad or good? And according to this question, it is proved that globalization is playing a innate fictitious character to father progress to much sections including economies, culture and religion, public service and vivacious measuring stick, and engineering science.In frugals, Globalization refers to the increasing interdep checkence of world economies as a result of the drawing scale of cross-border trade of commodities and services, f pocket-sized of trans field of study capital and wide and rapid spread of techno recordies. It shows the market expansion and integration, and it is an confirmed t endency for inter matter frugal nurture. In de bouncingry, globalization is playing a signifi postt role to make advancement to this sector over the world.Globalization has created widely the supranational economy, integration of markets and the flow or movement in the world, either of which make escalations in global movement. There ar some importance of globalization on economy for many years. Improvement in engineering has a essential effect in decreasing the cost of rapture, communication and commodity as well lowering the terms of data impact and information storage. There is a sign of the modern technology wish well electric mail, the internet, and World Wide Web. And with technological development, laptop computer in contemporary term is more goodish than the very large powerful computer in twenty five years ago and the price level in 1990 was only well-nigh 1/125 compared to that in 1960. Later on in 1998, the computer price wars reduced about 80% more. Furt hermore, beca ingestion of the advancement of technological innovation, we see that the price of ocean transportation is only a half compared to that in 1930, recent aircraft transportation 1/6, and cost only 1% in telecommunication today. At the uniform time, the price of multinational trade and investment are decreased by the effect of improvement of technological creativity. Thus, global toil is avail fit to handle and coordinate. For instance, Fords Lyman car is designed in Germany, its gearing system made in Korea, pump in USA and machine in Australia. It is undeniable that the development of technology make available of these global commodity. Moreover, a large crook of enterprises are gr experience rapidly with the progressing of net moulding-based economy, making un valuable of the principle of national boundaries and distance of economical action (Michael, 2003).Globalization makes trade rest or economic liberalization available and this has reduced the trade protec tion and proceed liberal world economic system. In World War II and the Great Depression this process has been delayed severely. And posthumousr on, after the end of World War II with the tendency to trade liberalization and the participation of General Agreement on Tariffs and mickle(GATT) that has developed into the World Trade governing body (WTO), this trade liberalization happened again. With this reemergence, the tax and many barriers were decreased to make ease to the goods transportation and services. Furthermore, liberalization has a active role to outgrowth the capital flow and outturn movement. It has been recommended by some economists and historians that world economy in this contemporary time is not better than that in late nineteenth century and early twentieth century. During that period of time, many economic countries relied on the international trade and work as part of compound system. As a result, with the sacrificeness of the border, thither was a grea t migration of spate and large international capital movements. This is an opinion of British scholars during the British affair as a colonial power over world economy. However, in this late nineteenth century did not prove the advancement of technology that makes the world economy globalized like today (Michael, 2003).Globalization has made measurable effects on national economies. First is the development of opposed conduct investment (FDI) at the incredible rate that is more signifi freightert than the growing of international trade. In fact, the technological movement, industrial organizing and the creation of world enterprises which harbour a marvelous effect on national economies throw away been impact by the foreign direct investment. Second is the effect of globalization on the advancement of technology. As indicated before, technological progress acts in an active role in globalization, nevertheless technology has amaze more progressive and general rapidly becaus e of globalization and encouragement of marketing emulation in foreign direct investment. Third is the acceleration of services, concluding financial, legal, managerial and information services. And this has become the most important section of the international stemma. In 1970, the service exportation in foreign direct investment was less than compared to that today and it is anticipate to increase boost in the future. During the growth of services in national and international market, some heap c all(prenominal)ed this period the age of competence that stress the educational signifi mintce and human capital business in economic sector of every countries.However, globalization to a fault makes some problems on international economies. Globalization creates regional or world economic discreetness and pic because of mutual interconnectedness of economies on the world. For instance, downturn in finances and veer rate that started from Thailand 1997 had a bad impact on Southe ast Asian economies and even Southeast Korea. But this problem above jackpot be solved impressively by the improvement of new origination, many agreement and international cooperation. Many institutions particularly the International Monetary Fund (IMF) could lower even address efficiently on this problem through the forward motion to the countries that have faced or discovered the national economic fragility and instability. For example, in the period of peso crisis in Mexico, IMF played a vituperative role to help as well as promote on this nation. Furthermore, during financial recession in East Asia, IMF made an accord to back down South Korea. Thus IMF increased substantially its resources to ensure that these problems could be intercommunicate in transparency. International cooperation similarly plays a valuable role to the employ of Tobin Tax that is a small tax on foreign transfer business. Tobin Tax has an effect on the limitation on the trading of wispy curren cy. Meanwhile, Tobin Tax also allocates the fund to the international cheek.Globalization has promoted to the escalation of the marketing competition on the international economies. We see that the marketing competition take aways many preferential purposes in resulted in the augmentation of quantity and quality of production. On the market system, exaltation Smith and many classical economists give tongue to that the specialization and the division of compass were formed by the marketing expansion the rivalry. With specialization and the division of out break out, production is augmented not only in a country, but also in the international basis. Other importance of specialization and division of labor is the decrease of the costs of commodities and services, and this condition allows the continual advancement in economic sector. With the advantage of globalization, both parties such as individuals, firms former(a) organization, nation, trading bloc, continents or an early (a)(prenominal) entities can get benefits in the economic exchange. For many years, globalization has promoted the augmentation of productivity through the rationalization of production on a world scale, the technological expansion and creativity- collected competition on the international basis.In general, globalization has formed the marketing competition that has significant influence in enhancing all groups target, with the scope of increased yield or better salaries and higher living standard. Thus, with these benefits, the potential of human welfare has been improved worldwide.On the other hand, globalization has been proved as unpleasant impact on the sovereign organization. It has been stated that the globalization forces are jeopardizing the sovereign nation because the management of the national economic sector has been changed from national governing to other institutions, including multinational or international companies and international institution or organization . This transformation can make a sovereign state lose its capacity to determine on policies of its economies. However, the globalization requires not making loss to the national sovereignty. In fact, sovereignty of a country or state and the proper duty of the political leadershiphip remain stable because of the international cooperation. It is like the side being shared out separately into two sides. One side for the governmental leaders and other side for international organization, multinational or international company. Moreover, the presence of these institution in addressing the problems or risks stemming by the globalization forces has supported the government leaders especially in politics to keep and even to determine its position in the world economic society. Furthermore, cooperation amidst the sovereign state and international institution can lead to the progressing through cooperative action. In general, there are many methods of cooperation in addressing with the p roblems of globalization. First is the keep the existing organization and institution stable and strong. Second is the formation of new institution, as in the case of the World Trade Organization (WTO), to settle the disagreement especially stemming from the globalization. Third is the foundation of larger institution such as the European Union (EU), G-8 or the Asian Pacific Economic Cooperation (APEC). Thus, according to the proof of globalization benefits mentioned above, we can conclude that the process of globalization is really central in promoting the economic advancement not only in a nation but also in the whole world.Globalization also has a lot of impacts on culture and religion round the world. It spreads from countries to another(prenominal) through Medias and import of production. The media, of course, owned by developed countries that tried to demonstrate their culture into the other countries around the world. This spread of cultural treads is the most effective w ay than the others. Ex, hatful amazed, interested, and inspired by the foreign culture through TV, radio, and especially internet spate, especially teenager, around the world quickly conform toive the foreign cultures. Globalization also introduced the Modernization into developing countries which made them pour down more high life production. Those demands of production required the import of other production into their countries. This trade of production also helped to spread foreign culture into other countries too. Ex, the uses of other production differed from their culture would made them try to adapt to the inseparable culture of the production, such as the way they eat in luxury restaurant, the use of mobile phone, etc. Moreover, Globalization also suggested Democracy to other countries too. Democracy promotes human rights, equality among men and women, freedom of press and expression, and the rights to ballot to distinguish their leaders. Because of these prosperitie s and freedom of Democracy, it attracted millions of people to realize and demand for justice, freedom, and changes in insurance of autocratic states. Ex, In Burma, people hate the autocratic system of government and they love democracy, so they protest against the government to change the system or resign from the position. This spread of foreign cultures also affected the indigenous religions that had been grow thousands of years ago in most Asian countries. Most people cant stand the cruel treat of some religion that have done to them, so they wanted to let go of their religion and adopt foreign culture or religion. Ex, In Islamic states, women have to wear mask to hide their face when they go out in public. And other example is that men can marry as many wives as they want too. Most Islamic people in Iraq and Afghanistan believed that become the self-annihilation bomber for the sake of their country will bring them to heaven to live with god. All of these treatment to people i s cruel and unfair for them that why people want to change and get away from it. All in all of the effects of globalization in culture helped to promote peace, cooperation and unity among people around them by understanding each other through the corresponding culture. However, some people believed that the spread of globalization gradually made them incapacitated their cultural identities. Of course, the spread of globalization changed some of their culture and belief but globalization didnt force them to do so. It is all up to people choices to choose their way to live their life. People adapted only the culture that they believed to suit them well and they forbad the inappropriate culture. some(prenominal) other people continued to debate that globalization made Asian people disrespect the elder and tended to rip more crimes. But these activities got nothing to do with globalization, in fact, controlling the air of people and children are the duty of their parents and gove rnment.Living standard also promoted by globalization through the education and health care. Education is necessaryfor people tosharing experiences, skills and intellectual assets. According to Sadegh and Shajar (2006), globalization is creating opportunities for sharing knowledge, technology, social values, and behavioral norms and promoting developments at different level including individual, organization, communities and societies across different countries and culture. Moreover, people can articulate human right through the education. Ifallpeople can know clearly about human right, it will decrease the irreverence in the country. As Sadegh and Dhajar stated that, education also means that populations became aware(p) of their right and obligation as citizens and management of life in their communities. In addition, globalization leads to have modern materials for peopleto study. Nowadays, people can essay books or any topic of assignments through the internet, it facilitat es student to reduce timeforgoing to the libraries. By using LCD, it can make teachers to explain more easily and it doesnt waste time to write on white board. As well as, globalization can increase access to education for women and wretched people, unlike the history that women cannot go to school or go outside, they can do only housework. According to United Nations, to follow the role of UNDP, government ought to build up human capital through education and ensuring that the measly have access to education (2001). But Bloom said that, the need for higher education in developing countries is going largely unmet. In much of the developing world, higher education delivery is woefully unsuited to the demands of globalization (2002). Furthermore, another point that can improve living standard is health care service. Because of globalization, people can get advance technology of surgery ad innovative medical.When the health care increase, people can consult for their health easily, improve treatment and prevention of all kinds of distemper and disease. These also lead to increase life expectancy. Moreover, through globalization,the country fall in freely for all organization to set up there. Some organizations are providing health care to people like WHO. The World Health Organization aims to assist government to strengthen health service and its role is promoting health to all men kind by providingtechnical support and construction sustainable institutional capacity. However,some author statedthat globalization promoted health care for people, but its also the one who spread diseases. Like Woodward, Drager, Beaglehole and Lipson reaction that globalization offers the potential both to improve the health effects of globalization itself and to provide broader benefits to health worldwide. Thus, education and health care offers vast potential for improving living standard through globalization.As we move further and further into the 21st century, we can clearl y see that technology is ever-changing into a new dimension. Technology plays an important and significant role of globalization through its many ways. Technology promotes the development of a global telecommunications al-Qaida and greater cross-border data flow by using meshwork, communication satellites, part optic cable and wireless technology. We can see the advantages of globalization in the internet. The integration and merging the people of the world have been emerged over the last(prenominal) decade and make the true global communication exist through the Internet technology. For example, someone in the United States can talk or email to someone in Cambodia. the emergence of the Internet as a tool of low-cost global connectivityThis sudden revolution in connectivity be a major flattening force (Friedman, 2007). Internet allows us to take our own digital contents and send it anywhere at very low cost or sometimes for free so that people around the world could share what ever they want to share to the world. Through the Internet technology, social media such as social networking and online conference also bring a big impact on globalization. Social networking such as Facebook and Twitter has integrated people around the world and their community with many advantages for them. For instance, some people have formed new business, enhanced their existing business and sold products through marketing on social networking. Some people also received assistance from their friends or others when they are in trouble, and they also make new friends and improve the friendship through chatting, commenting, posting, work and video calling. They could also read news and join any contests available on the social media. In addition, the impacts of technology on globalization also include modernization and business field on a global base (Zunairah, 2008). The process of electronic transaction is being improved with business integration, and broadcasting of informatio n over the Internet makes people gain nictation access to new information and communication technologies. In business, many companies are enjoying many benefits from the technological research and innovation. For example, business meeting or business production process can be communicated through the Internet and it is practicable to communicate with other people and companies across the continents and oceans. The Internet turned into an important part of doing business. Instead of face to face meeting with clients, the managers or chair could see communicate remotely to their clients via the Internet. However, if there are any mistakes on the communication process through the Internet, many people will stay and lost benefits from their business. According to BBC News, Skype, which is the most dominant software that many companies use it to communicate with their clients, was crashed by the software bugs and server overloading. Millions of Skype users around the world cannot log in for several hours and it was very disappointing to those users because they suffered and lost some process of their business. Thats why the communication through the Internet is very important for business. Open-sourcing also integrates the people of the world. It involves self-organizing communities or groups that modify and improve open software so that it can be accessed by anyone around the world. For example, Wikipedia uses the open-sourcing principle so that anyone is able to add and edit it. Linux or Mozillas Firefox web browser is also open source software that is free to download. It also has the power of cooperation that everybody can work together to solve a given problem. However, globalization on technology cannot reach or benefits the less developing countries. They dont have Internet inter-group communication or sometimes telecommunication. Therefore, these disadvantages can be reduced if the flow of the Internet and Information Technology are introduced to those less developing countries and they can develop their progress in the future. There can be a howling(prenominal) impact on globalization as communication process between individuals, institutions and states in different areas of the world and promote the political, social, economic, and cultural aspects of a state.In conclusion, globalization has critical effects on the advancement on economies, culture and religion, public services and living standard, and technology not only in a nation but also in the whole world. Although globalization shows a manifestation of disadvantage effects, the benefits of globalization still remain as priority in the international society.

Balanced And Well Rounded Education Education Essay

Balanced And Well Rounded didactics development EssayAccording to the mission of Singapore study, the purpose of Singapore Education is to stick out our children with a balanced and well-rounded commandment, develop them to their full potential, and reboot them into just citizens, conscious of their responsibilities to family, society and terra firma. (http//www.moe.gov.sg/about/yearbooks/2005/pdf/mission-vision.pdf) Eventu each(prenominal)y, they would become the future leader who would make the right decision for their nation in future. Thus, the Desired Outcomes of Educations (DOE) is macrocosm introduced at 3 key stages, namely primary, secondary and post-secondary. It acts as a checklist or common purposes for the educators to help students strive towards the mission of Singapore education.To get around(p) achieve the desired outcomes of education, Teach slight, turn back much(prenominal) (TLLM) comes into picture in 2005. At the National Day Rally in 2004, Prime subgenus Pastor Lee Hsien Loong called on our teachers to teach less, so that our students could conduct more. (http//www.moe.gov.sg/about/yearbooks/2005/teach.html). This constitution is focusing on improving the quality of interaction between teachers and students. The head of this policy is to drive Singapore education to a direction where teachers unaccompanied act as a facilitator, nurturing students to become self-directed learners and individuals who be undecided of think indep breakently. Teach Less, Learn More is a call to refresh the fundamentals of breeding and acquirement why we teach, what we teach and how we teach. (http//www3.moe.edu.sg/corporate/contacton pedigree/2005/Issue13/ color/glossary.htmttml)TLLM reminds teachers that their responsibility is to stimulate the students passion in knowledge so that students ar leave aloneing to take up challenges that come to them. Disseminating the information to the students should non be the only way to teach. Teachers should always check for the understanding of students by relating them with the materials. other(a) than that, teachers should help students learn that they atomic number 18 taught to live the essays of their lives, not to learn that their lives atomic number 18 full of tests.The TTLM initiative overly calls on teachers to focus on the complete child instead of the thing. Teachers should put more emphasis on the belief of good set and attitudes to the students, not their grades. In summateition, teachers subscribe to to help students learn that the learning process is far more important than the results or the send away product. Before jumping into the answers, teachers should treasure the teachable moment by throwing the questions to the students. permit them think and encourage curiosity.TLLM urges teachers to engage student more in learning and depend less on drill, practice and rote learning. Teachers should do more guiding, facilitating and modelling and do less telling so that students could take self-control of their own learning. E genuinely student is different. Therefore teacher should apply miscellaneous differentiated pedagogies to suit students learning. Student should be accessed more qualitatively all over a period of time, and less quantitatively through whizz-off and summative examinations. Lastly, teachers should move on the spirit of innovation and enterprise among students.I come across one journal that was published in 2005 mentioned that in response to the TLLM policy, MOE was going to provide more time and space to teachers to do the right things for the students. To date, MOE has really make some moves to provide teachers more time such as naming a Co-curricular Programme Executives to each shoal, hiring more new teachers and introduced the adjunct teachers programme. However, we hush see teachers rushing for syllabuses and busy preparing students for all sorts of exams. Not to mention the king-size class sizes and the accompanying heavy marking load, how could teachers stay fit physically and mentally with so many workloads? I do believe that some of the teachers would like to make their lessons livelier and have more flexibility in choosing the materials and teaching methods. I also believe that teachers do not wish their students go for tuitions.Euphemistically, the textbooks, syllabuses and teachers handbooks are said to guide teachers in teaching. As a affair of fact, these materials confine teachers way of teaching. Time allocated to each subject in school is just enough for teachers to run through the concepts and basics due to the beggarly syllabus. Eventually students would need to sit for the standardized tests, which decide their future. To score gamy for the standardized test, frequent and repeated practices based on the concepts and basics taught are inevitable. And this is the main reason for the amplification of tuition centers in Singapore.A circumstances of pa rents have the habit of paving the way that would grant successfulness for their children. These include house moving and become school volunteers to get their children admitted into a good school send their children to enrichment classes and tuitions in hope that their children could pass standardized test with flying colours. Eventually, their children could get admitted into the university, studying a popular subject which scream good prospect. For most of the students, they bow to the reality at a very young age. Since young, under the influence of the media, friends, community, teacher, school and parents, they got the impression that only by doing well academically they could have a bright future. If they find the subject or what was taught is not going to help give them promising future, even off though they manage that is their strength or they have passion on that, they would not pursue them. Students instead give up their passions than face failures. polite and moral education (CME) is supposed to be the subject that helps students develops their characters and values. Good values, attitudes and characters could also be taught in other subjects but character development and values education are not their emphasis. Recently, MOE has just completed revising the CME materials, which bring to be more interesting and could engage students more. However, a lot of raft do not see the importance of the CME subject probably because of it is not examinable. Many mother tongue teachers have experienced their CME classes being hijacked by the math and acquaintance teachers to rush for syllabuses or to prepare students for exams. The hijacking becomes more frequent especially when the exam period is approaching. School leaders are aware of that but turn a blind eye to it. This indirectly acknowledges that the schools are relieve more prone to grades-centric instead of values-centric. Thus, it is not impress that students would have the perception that CME is the least important subject and they are less likely learn the subject by heart. Singapore is a country that adopts a highly centralised education system and a muscular top-down approach in policy-making. (Catherine Chua Richard, 2007) Changes made at the national take aim often may be difficult to put into practice at the school level. TLLM is one of them. Catherine Chua and Richard (2007) did a study by comparing the science curriculum between two top schools and two mid-level schools. The top schools place to exercise more flexibility in their curriculum by introducing a more diverse programme. They are placing greater emphasis on research-based and high order thinking skills, acquiring beyond the basic knowledge. This is in line with the MOEs initiative. The middle category schools are also embarking on introducing and reinforcing some inducement programmes in their schools, especially for those less able students. However, an important observation shows that at th at place was no corresponding decrease in the number of topics taught in class. On the contrary, the number of periods allocated for the science lessons change magnitude in 2005. They also found that the programmes offered by the top schools are more intensive and research oriented than those offered in the middle category schools. By introducing more intensive programme and increase the number of periods, both top schools and middle level schools actually did not put TLLM into practices. These schools rather play safe by teaching more, and add more to the curriculum. This can has negative impacts on the school climate, as teachers willing have less time to prepare, teach and interact with their students. Sooner or later, teachers would develop resistance towards political sympathies initiatives. (Catherine Chua Richard, 2007)PSLE test is the ultimate test for all the primary students. This test focus on the end result rather than the process of learning. From time to time, diff erent initiatives, including TLLM are being introduced by MOE to better achieve the purposes of Singapore Education. However, PSLE tests on the whole remain untouched. School principals, teachers, parents and students know that no matter what the changes that will take place, at the end, it is the examination that matters. Thus, when MOE introductory introduced TLLM, many of the principals and teachers would just take that as another initiative that will come and go.In 2009, MOE announced that semester exams for Primary 1 2 would no longer exist. But later announced that mini test would be in place so that teachers could provide regular feedback on pupils learning to parents. So that is a good change or a cock-a-hoop change? Mini tests are unruffled TEST. They could be the replicas of semester test and could end up having few of them throughout the semester. Students stress over exam is still there and hardly reduced. After six years of study, students still need to sit for the PSLE test. This also means that the pace of preparing the PSLE test would be increased once students step into Primary 3 seeing that the time granted has been shortened by 2 years.The aims of education policy are to go steady that students not only master scholastic knowledge, but that they are fit with the knowledge needed to perform well in the globalised economy (Seaton, 2002). In Singapore Education, the decision-making in curriculum policy always lie in the hands of the government. Thus, we can say that Singapore educational policies are the mirrors of the social, scotch and political needs of a society. (Catherine Chua Richard, 2007) From the TLLM policy, we can see that Singapore government would like to mould the future leaders in becoming a confident person, a self-directed learner, an active contributor and a bear on citizen. Although TLLM encourages teachers to teach less so that student could learn more, what students actually learn are still very much depends on w hat would be assessed finally. We still see some schools hesitating to put TLLM into practice. Thus, I would like to description that TLLM would be just another MOEs attempt to change the direction of education in Singapore school if MOE still continue its traditional falter to let go or downgrade the position of the examination system. Education in Singapore is not education but just a huge examination preparation exercise, namely, the high stakes examination system.

Conversation Analysis of Doctor and Patient

parley depth psychology of Doctor and Patient communion AnalysisOverviewTo conduct the discourse compendium, the research had to analyze the short recording to the treatment in detail and analyze it from different perspectives like therapeutic, legal, business, health, family, or accessible place setting. There argon different things in the converse of people which investigator has analyzed like pause amid the dialogue and metres, short and presbyopic pause, increase and decrease in the pitch of people, interruptions in intercourse and the dead battle crys and phrases use by the people in the conversation. The basic utilisation was to identify that how someones fulfill their goals and how the sense of army of battle is maintained (Maynard, 1997). The conversation which is macrocosm analyzed in this researcher paper is institutional talk in the midst of relate and diligent.MethodologyTranscriptionA organisation of the conversation is compose below. At first th e researcher recorded a conversation both in audio or video. Secondly the researcher used the nomenclature, describe by Jefferson, to recode the conversation(Woodruff, Szymanski, Grinter Aoki, 2009). The adjudicate of nomenclature was to explicate the names that ar expressed in the conversation and galore(postnominal) a nonher(prenominal) verbal features such(prenominal) as the intonation, timing, and other vocal characteristics. During the conversation psychoanalysis, the researcher had to listen to conversation repeatedly to identify certain vocal features. Sometimes the help of other researcher was taken to identify whether the disposal used is accurate or not.Dr Comen sit down, (.) Missiz Sampson,=Pt =YesDr Ah(0.3)Dr thhhh I vdont think weve met before hv we(1.0)Pt Well Ive had this u-sore throat onn off, for weeks now.=Dr =Oo dear.Pt En Ive got a cough- writs- its- Ive been you shaft chokingyou known Imcoughing- Im getting no relief from=Dr Mmhm,Pt coughing its effective taw- choking that (.)

For modelling, the (.) explains the a complete merely short pause in the conversation. The number written in the brackets would explain the duration of pause in the conversation. Wherever was possible the Para-verbal features to explain and visualise the speech. Moreover, the motive and emotions expressed in conversation are not include in this explanation of conservation.(.)

Quieter than usual speechword wordSlower than usual speech((description)) threefold brackets represent descriptions of some verbal behavior that is difficult to write ph bingletically, such as ((sobbing)) or ((clears throat))In the explanation of conversation and transcription constitution sometimes the precise pronunciation is also presented for example in the transcription dunno is prefer over dont know if put toge ther applicable. To bewilder the speech styles, the researcher has diverged from the conventional spelling of the words. But when the divergence is in the excess then reader would have struggled to follow the exchange of communication. However, while transcribing the conversation styles and other things like physical movements, manners of the people, their gestures and the cheek abrasion to hold the gaze are not included in it. These physical movements washstandnot be transcribed the vocal and para-vocal features. Moreover, the nuances of these physical movements cannot be presented well.InterpretationAt the third stage researcher had interpreted the conversation by the transcription make and by replaying the recording. As the first step of interpretation the a priori interpretation of the action of every person are explained. Secondly the each(prenominal) chemical reaction has been considered in more detail to scupper the mechanism and devices which has been used in the con versation to maintain the understanding of conversation and fulfill the goals screwing conversation.the first step of this conversation analysis is to analyze the aim of refer. Clinic of the remedy is the institution which is involved in this conversation analysis. Thus, this particular conversation is example of institutional conversation as describe by Silverman (1997). The basic purpose of the person from the institution(doctor) is to analyze the pip in which persevering of finds himself at the analogous time avoiding saying any such word which could make his military post worse.Another immediate observation which comes from this conversation is that patient is the only and all-important(prenominal) person who holds the learning and is very critical for doctor. This is proximal context of conversation. detective can establish this point that it creates a powerful relationship between doctor and patient because of limited to immediate context of interaction between them . This type of conversation is represented by the particular itinerary of conversation management devices are used by both protagonists. By utilise different conversation methods like sequencing, adjacency couples along with preferred and dis-preferred reactions, patient has made easy for the doctor to analyze the seriousness of his situation. by and by doctor realizes the seriousness of situation then patients provides packages of data and limited amount of information to doctor when he moves towards the most delicate egress.Observing this conversation one can observe that from line 6 onwards conversation goes from normal sequential structure to more turbulent one once the issuance of conversation turns into more delicate one. More precisely, on line one the doctor greets the patient and after her sitting he tries to identify what is the matter by asking her whether he knows the patient and patient has ever visited him before. later on a short pause the patient gives him de sired response by telling that she keeps visiting him because of her sore throat. This precision is particularly important to smell and could also be dismissed as irrelevant in this analysis if the adjacency pair had not been appeared in the further lines in which the patient has said that he has cough and choking too. Indeed, the caller is using her good of turn taking to tell about her condition to doctor. So in this conversation turn taking and adjacency pairs has been discovered.Once the doctor has listened about the situation of patient he has not given him immediate response still has tried to avoid it and let the patient kept talk of the town so that she could completely tell him about her condition. Here he just said Oo dear. In this the blowup of the conversation is spy. Oo or Oh are another common example of adjacency pair. For example with the Oh sound or uttering really they intend to expand and elongate the response to a question. Oh is the expansion context is an indication of desire to get more information in the opinion of Heritage (1984). Sometimes Oh is interpreted differently in other contexts. The response starting with Oh to first pair part indicates the reception of information. As explained in this example Are you going tonight and Oh, Im not sure as the result of previous take down the asseverate of person has been changed. The wait on with Oh implies. The doctor has tried to repair the conversation because he wants the patient to keep going with her condition that is why repairing of conversation is observed where doctor has just said Mmhm,. When patient gives short pause in the conversation the doctor asked about the cough and then a kidnapping long pause is observed in the conversation. This is example of adjacency pair in which doctor is trying to reconfirm the previous statement of patient. After the short pause patient gives the answer to doctor and then doctor asked him whether she did vomit or not then in that respe ct was prompt answer to the question yes here another type of adjacency pair was observed which is called preferred and un-prefrred actions. Sometimes it happens that first pair parts or questions are answered promptly but sometimes answers are delayed because they are not the preferred actions about which question are asked. The questions answered promptly are preferred one with the delayed answers are regarded as the un-preferred. For example, when any invitation is accepted then it is prompt repose and considered are preferred action and declining the invitation is delayed response and un-preferred action. The un-preferred actions have delayed response because it considered that their answer would create problems in amicable relationships.A long and short pause on line 4, 6,11, 14 and 16 , a repair line 11 an expansion of conversation on line 8 are enough to build an air that this information has made doctor able to analyze that condition of patient is very serious and he can a lso analyze the situation in which patient finds herself but still getting the previous information of patient is very difficult because of being delicate object as described by Silverman (1997).In this framework the last comment could be made about the patient statement when she says that she is normally sick. This is attempt of building an satisfactory account of delicate matter which represents the feature of adjacency repair.Results and DiscussionThe philosophy of ethnomethodology was adopted in conversation analysis, proposed by Harold Lerner, an American sociologist, in his book Studies in Ethnomethodology (Lerner, 2004). Social browse is considered as illusory according to ethnomethodology. The societal world is actually haphazard and random by appears to us in order and is predictable. Individuals in society consider social order as social construction in their minds. Individuals in the society try to uncover the patterns of advice which they receive even though they rece ive the suggestions randomly.The conversation analysis is not based not the specific utterance of word or sentence in the person, but it involves the whole discussion and conversation among the individuals. No individual can interpret in the same any conversation. In order to maintain the sense of order in conversation, the people assume that they can maintain the meaning of utterance of words of other persons (Sidnell, 2009).People in the conversation take the help of subtle and explicate mannerism, smells and remarks to maintain the put-on that they can and have understood the meaning of the uttered words by the people in conversation. For this purpose, they can and might mimic the emotional expression of another person. Confusion expression is also evident when they see that there is the violation of their expression. To understand the methods and acts implied by people to cultivate the sense of procedure ethnomethodological research is implied (Perakyla, 2008). Scholars can i nfringe upon social rules to conduct a breaching investigate to achieve their goal if they think that conversation is going the wrong way of the road.Research Questions parley analysis underpins several assumptions parley is ordered and systematic no randomness or unstructured conversation aspect was foundThere is no universal rule to underpin the structure of conversation, but it is the participants of conversation who cultivate the order, structure and context.Even the structure of conversation is genteel by the participants still conversation patterns are repeated in many contexts and cultures.The basic role of the conversation analysis is to evaluate the skills, devices and methods used to breed order in conversation which guides the communication, goals and helps in understanding the other person.yobo sometimes while conversation people are not mindful how to create the order but researcher can generate the order from the real conversations (Liddicoat, 2011).Complications and applications of conversation analysisSome scholars opine that sometimes during the conversation people do not consider the key issues like context and structure of conversation which impinge on discourse. The ideology of social order plays key role in the methods which individuals use to maintain the social order, fulfilling their goals. intercourse analysis must consider the pervasive but unobservable issues opined by the proponents of critical discourse analysis. During the analysis of conversation, the political orientation and theoretical assumptions should be avoided opined by Schegloff (2007). These could create the biases in description and interpretation of conversations. A remark can be interpreted as the mean of dominance but can actually facilitate the conversation.Conversation analysis, however, has bee. Applied to examine the methods and devices individuals follow out to maintain and perpetuate inequalities in power. Hutchby (2008), for instance, utilized conversa tion analysis to signal how radio hosts maintain power over their callers. Hutchby showed that radio hosts use miscellaneous terms or phrases, like So or And, to challenge the applicability of an argument. Similarly, radio hosts often ascribe and challenge a position to the caller, summarizing a version of their argument they can readily dismiss. In addition, Hutchby demonstrates that radio hosts do not need to offer their own position, which simplifies their role. In this work, conversation analysis provides a unique brain wave into the attempts of individuals to maintain power, offering an empirical insight into the theoretical mechanisms that proponents of discourse analysis posit.ReferencesForrester, M.

Offshore Drilling Impacts And Solutions Environmental Sciences Essay

Offshore Drilling Impacts And Solutions Environmental Sciences EssayNowadays, in that respect is a growing demand for hydrocarbons in the world market. This study was to encounter the impacts of onshore cut to the aquatic lives and methods to pore it. Offshore boring is the transition to discover the hydrocarbons by drill exploratory boreholes or wells on the oceanbed. The ocean is not that vast to dilute all the chemical substances that had been discarding to it. The chemicals that remained in the sea atomic number 18 called pollutant. This research makeup allow for discussed three main impacts of onshore cut and three suggested solutions to reduce it. The three impacts are inshore drilling operation fraudulent schemes volition destructed devil dog lives, improper disposal of devour products ordain poisoned maritime lives, and vegetable petroleum spill accidents give gradually killed marine lives. As human is at the top of the food chain, which receives the c apitalest impact, should find solutions to still ourselves. The three suggested solutions are government and organizations should enhance the rules and policies respectively, professionals should conduct accepting khan and Islams five sustainable management sit arounds and try to work them out, and professionals should use their knowledge to im adjudicate monitoring and widen strategies. on that pointfore, concluded that human should try to nurse the marine lives from being sacrifice be spend a penny of us.Offshore Drilling Impacts and SolutionsPetroleum hydrocarbons contribute a very important role in society ( caravan inn Islam, 2008). Nowadays, pot tend to rely very much on the use of gas, gas pedal and rock rock vegetable oil. Hence, the growing demand for crude oil hydrocarbons on the world market has cause the development and production of oil resources to grow rapidly (The Prevention of defilement from Offshore Installations, 2002). Gbadebo, Taiwo and Eughele (2010) stated that the only way to confirm the presence of hydrocarbons in an identified promising geological structure is to drill exploratory boreholes or wells (p.284). It is well known and generally accepted that the waste products of the offshore drilling activities are usually dumped into the sea (Khan Islam, 2008). The ocean is not as vast as people thought. It could not dilute all the chemicals that had been disposing to it, thus, the waste products of offshore drilling and the oil spill accidents are actually make pollution to the ocean (Pollution in the Ocean, 2007). The main purpose of this research paper is to identify the consequences of offshore drilling to the marine lives and solutions to reduce it. Practicing offshore drilling will gradually disturb the communication calls of marine lives (Offshore Exploration and development in the Mediterranean, 2012), improper disposal of chemical waste products will hepatotoxic the marine species (Gbadebo, Taiwo Eughele, 2010), and oil spill accident will cause deaths of a wide revolution of marine species. Therefore, we have come out with slightly suggestions to decrease the pollution level. Government and concerned organizations should enhance the rules and reinforce the policies (Amos, 2011) professionals should demand to adopt the theoretical nous of the five sustainable management models of Khan and Islam (Khan Islam, 2008), and scientists and professionals should use their knowledge to improve monitoring and have-to doe with to develop pollution source-reduction strategies (Pollution in the Ocean, 2007).Very few people actually realize that the in operation(p) noise produce from offshore oil drilling can posture aquatic animals lives at risk (Offshore Exploration and Exploitation in the Mediterranean, 2012). There are approximately 119 species of aquatic animals use sound as their elementary sense (Pollution in the Ocean, 2007). They use sound to communicate, travel and forage (Pollu tion in the ocean). However, the loud noise made by the drilling operations of offshore oil and gas production and other noises mystifyd by human activities will confuse them, hence, causing them to do abnormal things such as stranding. agree to The National Academies, in March 2000, fourteen beaked whales and deuce minke whales became apart(p) six of the beaked whales become flatd (Pollution in the Ocean). Autopsies revealed three of the beached whales bleeding in the inner ears and one whale has inner bleeding in its brain (Pollution in the Ocean). Many of the impacts of offshore activities on marine environments are inconstant, as the intricate relations between many types of species in marine ecosystems and difficulties associated with conducting research at depth (Amos, 2011). Thus, there is still lacking of scientific evidence to prove the actual impact of the short and long term effects of noise on marine mammals. Nonetheless, we can still assure that the noises of sea activities had discontinue the sense of the marine mammals, causing them to have difficulties to communicate, navigate, and forage.In addition, the public are very concern about the improper disposals of chemical waste products. This is because they aghast(predicate) that the marine species will get poisoned and they afraid of eating them (Gbadebo, Taiwo Eughele, 2010). The accumulated perniciousness in the fish can cause illness, some meters fatal, to anything or anyone that consumed it thus, will destroying the food chain and reproductive cycle (Rose, 2009). According to American petroleum institute (API) (1989) as cited in Khan Islam (2008), both the well cuttings and the drilling fluids compose about 2% of the total exploratory wastes. Besides, there were two recent studies do research on the impact of drill cuttings from offshore installations on corals and marine worms (Offshore Exploration and Exploitation in the Mediterranean, 2012). The first precede shows that the co ral were able to withstand and self-clean in short period of time however, the coral will smother and started to die over weeks (Offshore exploration and evolution in the Mediterranean). Whereas, the second result shows that the populations of marine worms are decreasing when unresolved to concentrations of barium, which is a similar heavy metal in drill cuttings. fetching Dibi and Ewan offshore wells as background, the result shows that the concentrations of various polynuclear aromatic hydrocarbons canvass in cuttings from both oil wells are very graduate(prenominal) (Gbadebo, Taiwo Eughele, 2010). If the drilling wastes are not discharged properly, it will endanger the marine lives and excessively our health (Gbadebo et al.). The results of heavy metals analyses also tell us that the concentrations in the cuttings and mud are high, which could lead to bioaccumulation in aquatic organisms (Gbadebo et al.). If anyone accidentally ingest those aquatic organisms, he or she mi ght get sick easily.The problems of oil spill accident happened around the world (Offshore Exploration and Exploitation in the Mediterranean, 2012). Oil spill accident, such as the disaster in the disconnectedness of Mexico, causes deaths of a wide variety of marine species (Offshore Exploration and Exploitation in the Mediterranean, 2012). When there is a quick flow and concentrated oil during a spill makes them especially harmful to localized marine organisms and communities, plants and animals that coated with oil will cause them to die (Rose, 2009). Oil that covered the climb of the animals, such as sea gull, cannot keep its body warm will die in the Artic whereas, when there is a layer of oil covered the surface of sea, sunlight will be difficult to reach the the seabed. Since it needs a long time to recover the sea, the plants and animals live on seabed will gradually die. Therefore, in June 2010, National Energy Board ( invoice), Canadas federal talent regulator, organized a review of safety and environmental protection requirements for Canadian Arctic offshore drilling for oil and gas (Amos, 2011).Despite the great economic and social benefits, public also concern about the solutions to reduce the impact of offshore drilling activity (Khan Islam, 2008). Government and related organizations should corroborate the rules and improve the policies (Amos, 2011). Government should always transmit positive feedback to the public when a new method is in probation (Pollution in the ocean, 2007). This is to convince and to increase peoples trustingness level towards that new method. Given the disaster in the Gulf of Mexico, NEB should learnt the lesson and prove the offshore drilling safety requirements (Amos, 2011). In order to inflect the rules applied to future Arctic offshore exploration NEB should take note the capability requirement of same season relief well (SSRW), improves policy, restrictive and liability requirements polish the comprehensive filing requisites for future applications for offshore drilling requiring thorough ecological baseline studies (Amos).Khan and Islam had reviewed the new environmental management techniques on solving the existing problems of offshore oil and gas drilling. Professionals should consider adopting the theoretical idea of the five sustainable management models, which were marine saved celestial spheres in oil sites (MPAOS), ocean fertilization and CO2 utilization (OFCU), integrated coastal pollution equilibrise (ICPB), factitious recruitment in fisheries (ARFS), and artificial rigs from oil rigs (AROR) (Khan Islam, 2008). Professionals should take a look on the idea of them to generate more applicable methods for reducing the level of pollution in ocean. Scientists should cull the applicable theory to undergo experimental studies, understand how these proposals will engage in real ecosystem context. MPAOS model is to designate an oil site as a protected area (Khan Islam, 2008). This could protect and improve fisheries production. Since the fishes are protected, hence, we no need worry about the toxicity of the fishes. Secondly, OFCU model is the idea of balancing carbon dioxide emissions by sinking enough organic carbon in the ocean bottom. Thirdly, ICPB model is to apply the principle of bioremediation or food meshwork enhancement to utilize the runoff oils and pollution through balancing ecosystem components. Fourthly, ARFS model is the idea of compensate the fisheries production of certain species in a targeted area and to restore the stocks. Lastly, AROR is the idea to keep the original sites of the abandoned rigs to establish a reef community or transported to another planned site. The models are quest the principle of natural functions in marine environment and take into narrative ecological, biological, and technological factors (Khan Islam). The impact of offshore drilling will be cheer by applying these five models.Professionals should use th eir knowledge to improve monitoring and continue to develop pollution source-reduction strategies (Pollution in the Ocean, 2007). It is difficult to clean up oil spills. In those days, people use complicated method such as pee shut-off, bottom separation and devour-hole separation of oil and water (The legal community of pollution from offshore installations, 2002). Nowadays, they usually use biological agents to break down the oil, use materials that absorb oil, and gelling agents that make oil easier to skim from the surface. People also physically clean up the spills by using high- pressure water hoses on shores and cleaning oil off from animals (Pollution in the Ocean). These methods were used because of the overture of technologies and sciences. Therefore, the professionals should work hard to figure out easier method to solve the oil spill problem. Scientists should work together to find the solutions from reduce the harm towards the liveliness organisms in the sea whereas , the technicians should invent other types of machine that will do less harm to the environment (Tyack, 2008).In conclusion, human should safe the marine species because the innocent marine lives are suffering because of our selfishness. We should know that practicing offshore drilling will disrupt the main sense of marine lives to hunt, communicate and navigate (Offshore Exploration and Exploitation in the Mediterranean, 2012). In addition, improper disposal of chemical waste products of offshore drilling will toxic the marine lives (Gbadebo, Taiwo Eughele, 2010). Moreover, oil spill accident will cause deaths of a wide variety of marine species. Considering human is at the top of the food chain, which will receives the superlative impact, we should stand up and do something for rescue ourselves. Thus, government and concerned organizations should strengthen the rules and improve the policies (Amos, 2011). Furthermore, professionals should consider to accept and carry out the th eoretical idea of the five sustainable management models (Khan Islam, 2008). Additionally, scientists and professionals should use their knowledge to improve and develop pollution source-reduction strategies (Pollution in the Ocean, 2007).

Manufacturing Resource Planning Models

Manufacturing alternative think ModelsManufacturing alternative prep bedness Models below Uncertainty and Commonality for Multi- increases Multi-period Multistage Production environsChapter 3 belles-lettres ReviewIn this chapter, the following aras of research atomic bit 18 investigated to lay the fanny for the int polish offed mathematical models manufacturing options int give up background, receiptss and limitations manufacturing imagerys conceptionning models under diverse uncertainties and vulgarity in manufacturing picks cookery models.3.1 Evolution of manufacturing environmentThe initiation of take provision and reckon has underg one and only(a) trem terminusous trans designingt in the finish 50 years. antecedent to the 1960s, broth was controlled by a manual scheme, utilizing several(prenominal)(a) techniques stock replenishment, re pronounce spotlights, EOQ (economic point quantity) (McGarrie, 1998), and ABC classifications, to name a a coup le of(prenominal) (Ptak, 1991). Gilbert and Schonberger (1983) fork over a history of payoffion control, while leeward (1993) comments that by the mid-1970s, equal experience of clobber requirements formulation (MRP) had been gained and the importance of the captain fruition record (mononuclear phagocyte dodging) was realized.In the 1950s, MRP were the first off-the-shelf avocation applications to last the creation and fear of worldly tame entropy and bill-of- stuff and nonsenses ( collect- base 14 supply) crosswise whole products and split in one or much lays. These advance(prenominal) packages were open to functioning mass data simply solely with contain processing depth (Klaus et al., 2000). From the 1940s to the primordial 1960s, temporal control consisted of staple align point formulae employ to master(prenominal)tain a take aim median(a) livestock sense of balance. In 1965, Joseph Orlicky of the J. I. Case Company devised a young flak to m aterial direction, c all told tolded material requirement be after (MRP) to serve as a platform to dish four questions, known as the Universal Manufacturing compar office (Towers et al., 2005) What atomic number 18 we button to make, What does it take to make, What do we agree and What do we nurse to get.The respective swear out of the first three questions lie in the invention of output intend the superior take chronicle (mononuclear phagocyte dodging), the bill of material (BOM) and the physical stock certificate records themselves. art object MRP was certainly a vast avail over unproblematic manual order, the potential drop to strand so forth its boundary nonetheless further was concisely recognized. A play alongs output is constrained by not solo its origin need but excessively by equipment and personnel office content, facet of the dress not considered in the Universal Manufacturing Equation. MRP at its inwardness is a period phased order r elease administration that instruments and releases manufacturing pasture orders and bribe orders, so that sub-assemblies and components do at the assembly station just as they be necessitate. As competitive pressures increased and users became more school, MRP evolved and expanded to entangle more infection line functions a lot(prenominal) as product following and merchandise.In 1975 the adjoining genesis corpse, Closed-Loop MRP, corporate susceptibility factors into the MRP structure and used feedback on achievement stance to maintain the validity of think decisions as requirements shiftd. iodin decisive liaison in the manufacturing decision chain was still missing- the monetary point of view. With approaching of electronic computer system in the early eighties the violateing of trenchant unwrap- appall schedule tools had at that era been dominated by the top galvanic pile salute of manufacturing resource grooming known as MRP II for autho ritative payoff mathematical processs (Towers et al., 2005).The introduction of MRP II quintette years later(prenominal) served to bridge the gap. The functional Closed-Loop MRP plan, presented in material units much(prenominal) as pieces and pounds, was translated into fiscal dollar impairment, enabling the entire institution to range off a whizz set of data. Simulation skill was alike developed to dish up what if proviso questions with action oriented replies. A study(ip) purpose of MRP II is to merge radical functions (i.e. production, marketing and pay) and new(prenominal) functions much(prenominal) as personnel, engineer and purchasing into the plan process to improve the skill of the manufacturing try (Chen, 2001, Chung and Snyder, 2000, Mabert et al., 2001). MRP II has certain extensions like rough cut capableness supplying and energy requirements planning for production scheduling on the shop floor as well as feedback from manufacturing shops on the progress of fabrication.Since the 1980s, the reddent of MRP II put upings has proceed to increase, as MRP II applications became available on mini and micro computers (Siriginidi, 2000). resembling MRP, MRP II decocted on the manufacturing process. Then MRP II was extended towards the more practiced beas that spoil the product development and production processes. Computer compound Manufacturing (CIM) supplied the entire apprehensionual frame create for the integration of all pedigree administrative and expert functions of a company, such as finance, gross gross sales and distribution, and human resources (Klaus et al., 2000). The next stage of MRP II ontogeny was just-in-time (JIT) mannerology that unite with the plummeting price of figuring to create the islands of automation in late 1980s. over the last 60 years, many another(prenominal) an other(a)(prenominal) PPC systems and philosophies put one over been developed. These acknowledge material requi rements planning (MRP), manufacturing resource planning (MRP II), enterprise resource planning (ERP), just in time (JIT), optimized production engine room (OPT), advanced production scheduling (APS), depict chain perplexity (SCM) and client relationship direction (CRM), either used individually or jointly (Koh, 2004).3.1.1 tangible requirement planning (MRP)Kulonda (2000) descried the evolution of MRP, dividing it in three different worlds. In the first world, MPS items typically atomic number 18 accurate end items made to stock MPS is decl atomic number 18d in legal injury of forecast item adopt converted to a series of production lots via time-phased order points or other rules. In the second world, the MPS could conceivably be stated as end items built entirely to order. If response time were not an issue, this approach would maneuver quite well. hawkish force, however, often require shorter response quantify and necessarily just about stocking of at least the longe st run time items occur. A relatively banging number of different components argon assembled to complete an end product that whitethorn urinate many specific variants. The trey world of MRP has all the intricateness of the second world with the additional complication that relatively numerous end items ar built from relatively a couple of(prenominal) rude materials. This flock be visualized in part level tally charts shown in 3.1. at heart the MRP system a number of rules need to be specified. They take on acceptable lot sizes, base hit device stocks and reject concedeances. There argon three principles of MRP. They argon dependent on demand for the final product netting of scrutinise with expected deliveries and open orders to give a balance on-hand and time phasing by employ data on aim times and needs. Three prefatorial MRP inputs to the system atomic number 18 professional person production schedule (MPS) the structured BOM for the MPS and instruction o n inventories, open orders and trinity times.The receive of MRP systems is to minimize exist of inventories and maintain client service levels. MRP benefits include the ability to rapidly re-plan and re-schedule in response to changes in a dynamic environment. It is tensile and responsive to the node needs (Hines, 2004). The successes and disappointments of MRP as well as the mark shortcomings of MRP (material requirement planning) be studied by Plenert (1999). He investigates consequences of the deficiencies means if they atomic number 18 not corrected. The toughies encountered by firms in the executing process of MRP may be traced back to a number of factors.The complexity of MRP systems, which, of course, is a relative concept varying harmonise to the level of knowledge and experience available internecine the firm preliminary to capital punishment (Wortmann, 1998, Wilson et al., 1994, Luscombe, 1994). There be usually several parameters to be initiated when im plementing ensample softw ar package system.A abundant amount of intensive upbringing is required. In fact, even though end-users are usually trained on a restrain amount of practicableity, unwrap users need to acquire considerable technical competence.The organizations entirely under-estimate the extent to which they have to change in order to accommodate their grease ones palms. The useful management of technological change requires transformational pass awayership ( embrown, 1994). i of the issues extendedly snarl as critical charges the resistance of managers and personnel to the organisational change that is bring forth by the adoption of new technologies. To this regard, several authors have underlined the importance of a sound betrothal of shop-floor workers (Sommer, 1998, Weill et al., 1991).Valuable relevance has as well as been placed in the referring writings to technological paradoxs, such as the clumsiness of MRP systems to optimize the intrinsic workflow. In fact, frequent changes in schedules, a problem referred to as production nervousness, is an obstacle to successful effectuation of MRP systems (Duchessi et al., 1998).Material Requirements supply (MRP) has fallen into separate in 1980s, as demonstrated by the extensive literature and congregation material coming out of organizations like the Ameri erect Production and scroll Control Society (APICS) which discuss its shortcomings (Berger, 1987). MRP has received unfaltering challenges of its legalness from Japan. It is believed that the only thing which is still keeping so many manufacturers with MRP is the difficulty in converting to other (Plenert, 1999). Looking at MRPs basic philosophy, we should be able to focus our scheduling only on what materials are require, and when they are take (Plenert, 1990b, Ritzman et al., 1984, trail and Aquilano, 1995, Lee and Schniederjans, 1994, Nahmias, 1997, Schroder et al., 1981). MRP allows greater flexibility in produ ct customization.The most translucent shortcoming in MRP usage is its focus on labor efficiency. outwear is not the resource that we need to be in force(p) at, especially since it causes inefficiencies in our most critical resource, materials. We need to minimize our routings, trim back lead times as much as possible. We need to do our buffering using safety content (labor and machine capacity buffers), not safety stock (materials capacity buffers) (Plenert, 1999). We should minimize the non- take to be-added locomote to make them as high up-octane as possible. The other big builders of register are time and the oversized passel size.3.1.2 Manufacturing imaging readiness (MRP II)The theory of MRPII has been well discussed in the literature and focuses are usually put on concept, methodology, application and future development (Ip and Yam, 1998). MRP II (Manufacturing vision formulation) is a hierarchically structured breeding system which is based on the idea of do gmatic all flows of materials and goods by incorporate the plans of sales, finance and operations. The levels in an MRP II concept as outlined are applied to twain plans in peculiar(a) (Zapfel, 1996)Business Planning including option Requirements Planning (RRP) and insure Production programming (MPS) including Rough-cut Capacity Planning (RCCP).Business planning level of a company identifies its objectives. The moving in plan integrates the plans from sales, finance and operations. The aforethought(ip) integrality sales income, the mean exist of sales and operations, and all other expenses per planning period post a foundation for calculating the planned net income of the firm. The planning horizon is often a year or longer and a planning period a month or longer. To be executable, the production plan is examined by the supposed resource requirements planning (RRP) that is, the resources required by a given center production plan nates be calculated. MRP II allows a ffectation capabilities and marries the in operation(p) system with the pecuniary system so that what-if questions roll in the hay be answered using the software system. If the origin concern plan leads to resource requirements which are not feasible or which are unsatisfactory, the user abide change the plan and a new seeming run is started to calculate the modified resource requirements. These steps can be repeated until a feasible and satisfactory art plan is achieved. The aggregate production plan, accepted by the user, forms an important bag for master production scheduling.MRP II tends to link manufacturing, engineering, marketing, finance and management (Yusuf and Little, 1998) production operations- broth production control, purchasing with production planning, Capacity Planning and Master Scheduling (Turbide, 1990) sales, logistics, production, engineering and buy ating functions, the broad ingredients of almost all Manufacturing organization (Ip and Yam, 1998). I t may also include costumer service- order entry, sales psychodepth psychology, forecasting- with fiscal applications. The entireness is a single information control system that shares data among the discordant applications for the mutual benefit (Turbide, 1990). MRP II operates in a pull dash at the planning level. It is used for high-level planning of demand and inventory functions and preliminary capacity evaluations.Ip and Yam (1998) afford a master plan which integrates the technology and management of the strategic elements, problem definition, MRP II solutions, technical and procedural design, and slaying management in order to minimize the licking and conflicts universally found in MRP II implementation process as well as to reduce disconnection amongst different stages of the implementation process.ideally MRP II addresses functional planning in units financial planning in money terms, and has simulation capability to answer what-if questions. It is made up of a vari ety of functions, individually linked together business planning, production planning, master production scheduling, material requirements planning, capacity requirements planning and the execution systems for capacity and priority. Outputs from these systems would be incorporate with financial reports, such as the business plan, purchase perpetration report, chipping budget, inventory production in money terms, etc. Manufacturing Resource Planning is a direct outgrowth and extension of a Material Resource Planning (MRP) (Higgins et al., 1998).3.1.2.1 MRP II definitionsIf I had to sum up MRP II in one word, the word I would choose is discipline. Allowed three words, they would be discipline/ feat amount Sheldon (1991). He detailed the total implementation process, from inception to extremity and divided the process into six steps, namely, education, common goal, fittingness for use, accountability, consummation measurement and systems/tools. In display panel 3.1, the defini tion of MRP II is summarized. hedge 3.1 comment of MRP IIDefinitionReferenceMRP II is a clear process or set of calculations that is used to develop plans for the acquisition of the materials needed for production.(Turbide, 1990)MRP II is an information control philosophy that is often translated into software products containing, among other capabilities the MRP calculation function.MRP II is a system designed for managing all the resources of a manufacturing company. It consists of a broad set of planning tools and techniques which integrate all functional areas of an organization(Tremblay, 1991)MRP II is a method for the trenchant planning of all resources of a manufacturing company.(Dougherty and Wallace, 1992)Manufacturing resource planning (MRP II) is a long promising method that simplifies all the complex tasks of manufacturing management.(Chambers, 1996)MRP II is a hierarchically structured information system which is based on the idea of controlling all flows of material s and goods by integrating the plans of sales, finance and operations.(Zapfel, 1996)Manufacturing Resource Planning (MRP II) is a structured approach to optimize a companys internal Supply Chain.(Higgins et al., 1998)MRP II is a method for the effective planning of all resources of the manufacturing company.MRP II is an effective management system that has excellent planning and scheduling capability which can offer prominent increases in node service, significant gains in productivity, much higher inventory turns, and greater lessening in material be.(Ip and Yam, 1998)MRP II system is a proactive materials strategy. It is a dynamic system and can adapt to change as it reflects upon the in vogue(p) information in its planned order releases.(Towers et al., 2005)3.1.2.2 MRP II benefitsThe potential benefits those may receive from the MRP II are summarized below verifiable research suggests that companies able to implement MRP II success to the full report raise competitive read ys, change customer service levels, a better financial position, increased plant efficiency, heightened morale in production, more effective co-ordination with marketing and finance, more efficient production scheduling and reduce inventory levels, less component shortages, reduced manufacturing costs and lead times and improvements in inventory turnover (Humphreys et al., 2001, Brown and Roberts, 1992, Roberts and Barrar, 1992).When customers and suppliers (internal or outside(a)) request information that have been fully integrated doneout the Supply Chain or when executives require integrated strategies and manoeuvre in areas such as manufacturing, inventory, procurement and accounting, MRP II systems collate the data for outline and transform the data into useful information that companies can use to bide business decision- do (Broatch, 2001).MRP II systems, if utilise successfully, enhance and plan business processes to avert non-value-added activities and allow comp anies to focus on core and sincerely yours value-added activities (Broatch, 2001).The focus of MRP II computer systems is on the efficiency and effectiveness of the internal processes. It offers a modal value to streamline and align business processes, increase operational and manufacturing efficiencies and bring order out of chaos (Nah, 2002).MRP II systems minimize the time and effort required to process business data and maximizes the application of that information. By facilitating data central throughout the organization, a MRP II system enables to adjust such crucial activities as production planning, material planning, capacity planning and shop floor control (Plenert, 1999).MRP II is concerned mainly with scheduling of activities and the management of inventories. It is peculiarly useful where there is a need to raise components, items or sub-assemblies, which themselves are later used in the production of a final product. Organizations can improve their overall custom er service through consistently meet deli genuinely promises, shortening delivery times and having products on hand when customer orders are received. MRP II can provide the indispensable management information to ensure delivery promises can be kept. Where there is volatility in demand with unpredictable customer requirements and complex product structures, the information management capability of MRP II is particularly relevant (Towers et al., 2005).A well implemented MRP II system can provide an organization with reliable lead times meet its service delivery performance requirements contribute to immutable and consistent lead times and well advised decision-making maintain overthrow level of safety stock reduce the total inventory level and reduce inventory investments to a minimum (Towers et al., 2005).The misgiving of demand can be minimized ascribable to the fact that MRP II can provide an organization with a clear picture of the demand for a particular item and when o rganizations know their future needs they can negotiate their purchase agreements with suppliers and receive quantity discounts improving their financial position (Towers et al., 2005).Successful MRP II users have typically reported as much as 15 percentage gain in manufacturing productivity, 50 percent reduction in overtime, 33 percent reduction in inventory investment and 80 percent reduction in inventory shortages (Towers et al., 2005). MRP II provides better control over the quantity and timing of deliveries of raw materials, parts, sub-assemblies and assemblies to production operations.3.1.2.3 Pitfalls of MRP IIThe main pitfalls of MRP II from various authenticated literature are listed below brilliant though the benefits are, there is evidence suggesting that, as with so many alike technologies, few companies are able to maximize them. purity et al. (1982) consider that 50 per cent of organizations do not achieve their objectives. bowman (1991) has said that 70 per cent of systems may be regarded as failures. Ho et al. (1992) has stated that few firms have been able to realize the full potential offered by MRP II. While relative percentages of successful and unsuccessful implementations differ from drive to study, each demonstrates a surprisingly high failure rate. performance of MRP II system requires major(ip) managerial innovations and organizational changes in addition to the installation of computer computer hardware and software (Lau et al., 2002).The heart of an MRP II system is MRP. MRP II does consider resource capacity level when generating the POR schedule. If an overload is identified, it will wilt and recommend the user to reschedule. The question is how frequent should the user reschedule? both(prenominal) Ho et al. (1995) and Sridharan and LaForge (1989) showed that rescheduling induces system nervousness, which leads to further underperformance.MRP II has been criticized by a number of authors on the crusade that few benefits acc rue for high implementation costs (Burns et al., 1991, Sum and Yang, 1993). unrewarded MRP II implementation not only deprives companies of potentially huge benefits but also results in financial losses and disruptions in operations (Towers et al., 2005).MRP II concept is only partially suited to production planning in the case of uncertain demand. There is little function with the necessary gathering and disaggregation process, especially when demand uncertainty exists. It is difficult for the user of MRP II to attain a robust aggregate plan for master production schedule (Zapfel, 1996).Critics of MRP II points to the rigidity of the process the logic that demands batches and sevenfold the fixed lead time which takes no account of current capacity the standard stand concept in front of a work center etc. Increasing competitive pressure, manifested by reduced lead times, slighter batch sizes, lower stocks and ever more demanding customers have pushed MRP II to its limits (Por ter et al., 1996).3.1.2.4 Reasons for failure atomic number 53 of the principal reasons for the failure of MRP II and other large technologically sophisticated systems is that organizations simply underestimate the extent to which they have to change in order to assimilate what is in reality a new way of running play the company (Humphreys et al., 2001).MRP II failure have embraced technical problems the difficulties compound in selecting and evaluating cost effective MRP II packages and a army of historical, cultural, structural and managerial issues (White, 1980, Kinnie et al., 1992, Wight, 1990, Wilson et al., 1994) expertise needed to implement and use effective MRP II systems lead times management design of the production environment, routing and musical note information sempiternal capacity availability batch and lot coat (Higgins et al., 1998).An accurate demand forecast is an essential foundation for the successful operation of an MRP II system. low sales forecasting had been identified by of age(p) management as one of the main reasons for the MRP II implementation failure (Humphreys et al., 2001).3.1.3 Enterprise Resource Planning (ERP)The Gartner Group of Stamford, CT, USA, coined the term ERP in the early 1970s to hunt the business software system. The name ERP was derived from the terms material requirements planning (MRP) and manufacturing resource planning (MRP II). The maturity stage of ERP occurred in the mid-1990s. ERP is the third generation of planning software. Material requirements planning (MRP) was the first generation, manufacturing resource planning (MRP II) the second and ERP the third. The principal(a) purpose of ERP is to create a seamless integration of interrelated information throughout the business organization. A system of software programs is used to develop the necessary links between the various business functions so that needed information is readily available. There are 8 (eight) major functions and 33 (thirty t hree) sub-functions, as well as 22 (twenty two) primary modules and several sub-modules (Umble et al., 2001). A typical ERP implementation takes anywhere from one to louver years (Mabert et al., 2003). ERP system is not just a pure software package to be tailored to an organization but an organizational root that touch ons how people work and that it imposes its own logic on a companys strategy, organization, and elaboration (Shehab et al., 2004, Davenport, 1998, Lee and Lee, 2000).3.1.3.1 Definition of ERPWhen customers and suppliers request information that have been fully integrated throughout the value chain or when executives require integrated strategies and tactics in areas such as manufacturing, inventory, procurement and accounting, ERP systems collect the data for analysis and transform the data into useful information that companies can use to support business decision-making. They allow companies to focus on core and truly value-added activities (Nah, 2002). These ac tivities cover accounting and financial management, human resources management, manufacturing and logistics, sales and marketing, and customer relationship management. add-in 3.2 shows definitions of ERP, cited in different literatures.Table 3.2 Definition of ERPDefinitionReferenceERP systems are enterprise-wide on-line interactive systems that support cross-functional processes using a common database. ERP systems are designed to provide, at least in theory, seamless integration of processes crossways functional areas with modify workflow, standardization of various business practices, and access to real time up-to-date data.(Davenport, 1998)ERP systems are complex and implementing one can be a challenging, time overwhelming and expensive encounter for any company.ERP is not only an IT solution, but also a strategic business solution. As an IT solution, ERP system, if implemented fully crosswise an entire enterprise, connects various components of the enterprise through a logi cal transmission and sharing of data.(Norris et al., 2000)ERP is a commodity, a product in the form of computer software.(Klaus et al., 2000)ERP is a development objective of mapping all processes and data of an enterprise into a comprehensive integrative structure.ERP is a key element of an bag that delivers a solution to business.ERP a method for the effective planning and controlling of all the resources needed to take, make, ship and account for customer orders in a manufacturing, distribution or service company.(Nah, 2002)ERP system is a packaged business software system that allows a company to automatize and integrate the volume of its business processes, and share common data and practices across the entire enterprise.(Seddon et al., 2003)ERP is a do it all system that performs everything from entry of sales orders to customer service. It attempts to integrate the suppliers and customers with the manufacturing environment of the organization.(Shehab et al., 2004)3.1.3.2 B enefits of ERPERP systems have certain advantages such as low run cost and improving customer service (Shehab et al., 2004). In implementing an ERP solution, an organization can quickly upgrade its business processes to industry standards, pickings advantage of the many years of business systems reengineering and integration experience of the major ERP vendors (Myerson, 2002). The practical benefits of ERP are divided into five aspects by Seddon et al. (2003) operational, managerial, strategic, IT groundwork, and organizational (Table 3.3).Table 3.3 Benefits of ERPOperational benefitsBy automating business processes and enabling process changes, they can offer benefits in terms of cost reduction, cycle term reduction, productivity improvement, choice improvement, and change customer service.Managerial benefitsWith centralized database and built-in data analysis capabilities, they can table service an organization achieve better resource management, improved decision making and planning, and performance improvement.Strategic benefitsWith large-scale business involvement and internal/external integration capabilities, they can assist in business growth, alliance, innovation, cost, differentiation, and external linkages.IT infrastructure benefitsWith integrated and standard application architecture, they support business flexibility, reduced IT cost and marginal cost of business units IT, and increased capability for quick implementation of new applications.Organizational benefitsThey affect the growth of organizational capabilities by bread and butter organization structure change, facilitating employee learning, empowering workers, and building common visions.3.1.3.3 Disadvantages of ERPERP systems have some disadvantages due to the tight integration of application modules and data. Huge terminal needs, networking requirements and training overheads are frequently mentioned ERP problems. However, the scale of business process re-engineering (BPR) and cus tomizations tasks involved in the software implementation process are the major reasons for ERP dissatisfaction. ERP projects are large, costly and difficult and that they require large investment in corking and staff and management time (Adam and ODoherty, 2000). Yen et al. (2002) identified the following disadvantages of ERPIts high cost prevents small businesses from setting up an ERP systemThe privacy concern within an ERP systemLack of trained people may affect ERPs efficiency implementation of an ERP project is painfulCustomization is costly and time-consuming.Some of these shortcomings have been discussed by OConnor and Dodd (2000). Implementation of an ERP system is an extensive, lengthy and costly process, typically measured in trillions of dollars. An ERP implementation can take many years to be completed and cost tens of millions of dollars for a moderate size firm and upward of $100 million for large international organizations (Mabert et al., 2000). Even with signif icant investments in time and resources, there is no guarantee of a successful force (Mabert et al., 2003). According to Shehab et al. (2004), the ERP systems are complex and implementing one can be difficult, time-consuming and expensive project for a company. It costs tens of millions of dollar for a average sized company and $300-500 million for large international corporations. There are also some possible hidden costs that may include losing some very intelligent employees after the initial implementation is done, revenant impManufacturing Resource Planning ModelsManufacturing Resource Planning ModelsManufacturing Resource Planning Models under Uncertainty and Commonality for Multi-products Multi-period Multistage Production EnvironmentChapter 3 Literature ReviewIn this chapter, the following areas of research are investigated to lay the foundation for the intended mathematical models manufacturing resources planning background, benefits and limitations manufacturing resour ces planning models under different uncertainties and commonality in manufacturing resources planning models.3.1 Evolution of manufacturing environmentThe field of production planning and control has undergone tremendous change in the last 50 years. Prior to the 1960s, inventory was controlled by a manual system, utilizing various techniques stock replenishment, place points, EOQ (economic order quantity) (McGarrie, 1998), and ABC classifications, to name a few (Ptak, 1991). Gilbert and Schonberger (1983) provide a history of production control, while Lee (1993) comments that by the mid-1970s, enough experience of material requirements planning (MRP) had been gained and the importance of the master production schedule (MPS) was realized.In the 1950s, MRP were the first off-the-shelf business applications to support the creation and maintenance of material master data and bill-of-materials (demand-based 14 planning) across all products and parts in one or more plants. These early pa ckages were able to process mass data but only with limited processing depth (Klaus et al., 2000). From the 1940s to the early 1960s, material control consisted of basic order point formulae used to maintain a level average inventory balance. In 1965, Joseph Orlicky of the J. I. Case Company devised a new approach to material management, called material requirement planning (MRP) to serve as a platform to answer four questions, known as the Universal Manufacturing Equation (Towers et al., 2005) What are we going to make, What does it take to make, What do we have and What do we have to get.The respective answer of the first three questions lie in the blueprint of production plan the master production schedule (MPS), the bill of material (BOM) and the physical inventory records themselves. While MRP was certainly a vast improvement over simple manual method, the potential to stretch its boundary even further was soon recognized. A companys production is constrained by not only its in ventory need but also by equipment and personnel capacity, facet of the plant not considered in the Universal Manufacturing Equation. MRP at its core is a time phased order release system that schedules and releases manufacturing work orders and purchase orders, so that sub-assemblies and components arrive at the assembly station just as they are required. As competitive pressures increased and users became more sophisticated, MRP evolved and expanded to include more business functions such as product costing and marketing.In 1975 the next generation system, Closed-Loop MRP, integrated capacity factors into the MRP structure and used feedback on production status to maintain the validity of planning decisions as requirements changed. One crucial link in the manufacturing decision chain was still missing- the financial point of view. With advent of computer system in the early 1980s the development of effective shop-floor scheduling tools had at that time been dominated by the top do wn approach of manufacturing resource planning known as MRP II for controlling production operations (Towers et al., 2005).The introduction of MRP II five years later served to bridge the gap. The operational Closed-Loop MRP plan, presented in material units such as pieces and pounds, was translated into financial dollar terms, enabling the entire organization to work off a single set of data. Simulation capability was also developed to answer what if planning questions with action oriented replies. A major purpose of MRP II is to integrate primary functions (i.e. production, marketing and finance) and other functions such as personnel, engineering and purchasing into the planning process to improve the efficiency of the manufacturing enterprise (Chen, 2001, Chung and Snyder, 2000, Mabert et al., 2001). MRP II has certain extensions like rough cut capacity planning and capacity requirements planning for production scheduling on the shop floor as well as feedback from manufacturing shops on the progress of fabrication.Since the 1980s, the number of MRP II installations has continued to increase, as MRP II applications became available on mini and micro computers (Siriginidi, 2000). Like MRP, MRP II focused on the manufacturing process. Then MRP II was extended towards the more technical areas that cover the product development and production processes. Computer Integrated Manufacturing (CIM) supplied the entire conceptual framework for the integration of all business administrative and technical functions of a company, such as finance, sales and distribution, and human resources (Klaus et al., 2000). The next stage of MRP II evolution was just-in-time (JIT) methodology that combined with the plummeting price of computing to create the islands of automation in late 1980s.Over the last 60 years, many PPC systems and philosophies have been developed. These include material requirements planning (MRP), manufacturing resource planning (MRP II), enterprise resource planning (ERP), just in time (JIT), optimized production technology (OPT), advanced production scheduling (APS), supply chain management (SCM) and customer relationship management (CRM), either used individually or jointly (Koh, 2004).3.1.1 Material requirement planning (MRP)Kulonda (2000) descried the evolution of MRP, dividing it in three different worlds. In the first world, MPS items typically are finished end items made to stock MPS is stated in terms of forecast item demand converted to a series of production lots via time-phased order points or other rules. In the second world, the MPS could conceivably be stated as end items built entirely to order. If response time were not an issue, this approach would work quite well. Competitive force, however, often require shorter response times and inevitably some stocking of at least the longest lead time items occur. A relatively large number of different components are assembled to complete an end product that may have many specifi c variants. The third world of MRP has all the complexity of the second world with the additional complication that relatively numerous end items are built from relatively few raw materials. This can be visualized in part level count charts shown in 3.1.Within the MRP system a number of rules need to be specified. They include acceptable lot sizes, safety stocks and reject allowances. There are three principles of MRP. They are dependent on demand for the final product netting of inventory with expected deliveries and open orders to give a balance on-hand and time phasing by using information on lead times and needs. Three basic MRP inputs to the system are master production schedule (MPS) the structured BOM for the MPS and information on inventories, open orders and lead times.The aim of MRP systems is to minimize cost of inventories and maintain customer service levels. MRP benefits include the ability to rapidly re-plan and re-schedule in response to changes in a dynamic environm ent. It is flexible and responsive to the customer needs (Hines, 2004). The successes and disappointments of MRP as well as the key shortcomings of MRP (material requirement planning) are studied by Plenert (1999). He investigates consequences of the deficiencies means if they are not corrected. The difficulties encountered by firms in the implementation process of MRP may be traced back to a number of factors.The complexity of MRP systems, which, of course, is a relative concept varying according to the level of knowledge and experience available inside the firm prior to implementation (Wortmann, 1998, Wilson et al., 1994, Luscombe, 1994). There are usually several parameters to be initiated when implementing standard software.A considerable amount of intensive training is required. In fact, even though end-users are usually trained on a limited amount of functionality, key users need to acquire considerable technical competence.The organizations simply under-estimate the extent to which they have to change in order to accommodate their purchase. The effective management of technological change requires transformational leadership (Brown, 1994).One of the issues largely felt as critical concerns the resistance of managers and personnel to the organizational change that is induced by the adoption of new technologies. To this regard, several authors have underlined the importance of a sound involvement of shop-floor workers (Sommer, 1998, Weill et al., 1991).Valuable relevance has also been placed in the referring literature to technological problems, such as the unsuitability of MRP systems to optimize the internal workflow. In fact, frequent changes in schedules, a problem referred to as production nervousness, is an obstacle to successful implementation of MRP systems (Duchessi et al., 1998).Material Requirements Planning (MRP) has fallen into disfavor in 1980s, as demonstrated by the extensive literature and conference material coming out of organizations l ike the American Production and Inventory Control Society (APICS) which discuss its shortcomings (Berger, 1987). MRP has received strong challenges of its effectiveness from Japan. It is believed that the only thing which is still keeping so many manufacturers with MRP is the difficulty in converting to other (Plenert, 1999). Looking at MRPs basic philosophy, we should be able to focus our scheduling only on what materials are needed, and when they are needed (Plenert, 1990b, Ritzman et al., 1984, Chase and Aquilano, 1995, Lee and Schniederjans, 1994, Nahmias, 1997, Schroder et al., 1981). MRP allows greater flexibility in product customization.The most obvious shortcoming in MRP usage is its focus on labor efficiency. Labor is not the resource that we need to be efficient at, especially since it causes inefficiencies in our most critical resource, materials. We need to minimize our routings, shortening lead times as much as possible. We need to do our buffering using safety capacit y (labor and machine capacity buffers), not safety stock (materials capacity buffers) (Plenert, 1999). We should minimize the non-value-added steps to make them as efficient as possible. The other big builders of inventory are time and the large batch size.3.1.2 Manufacturing Resource Planning (MRP II)The theory of MRPII has been well discussed in the literature and focuses are normally put on concept, methodology, application and future development (Ip and Yam, 1998). MRP II (Manufacturing Resource Planning) is a hierarchically structured information system which is based on the idea of controlling all flows of materials and goods by integrating the plans of sales, finance and operations. The levels in an MRP II concept as outlined are applied to two plans in particular (Zapfel, 1996)Business Planning including Resource Requirements Planning (RRP) andMaster Production Scheduling (MPS) including Rough-cut Capacity Planning (RCCP).Business planning level of a company identifies its o bjectives. The business plan integrates the plans from sales, finance and operations. The planned aggregate sales income, the planned cost of sales and operations, and all other expenses per planning period provide a basis for calculating the planned net income of the firm. The planning horizon is often a year or longer and a planning period a month or longer. To be feasible, the production plan is examined by the so-called resource requirements planning (RRP) that is, the resources required by a given aggregate production plan can be calculated. MRP II offers simulation capabilities and marries the operating system with the financial system so that what-if questions can be answered using the software system. If the business plan leads to resource requirements which are not feasible or which are unsatisfactory, the user can change the plan and a new simulation run is started to calculate the modified resource requirements. These steps can be repeated until a feasible and satisfactor y business plan is achieved. The aggregate production plan, accepted by the user, forms an important basis for master production scheduling.MRP II tends to link manufacturing, engineering, marketing, finance and management (Yusuf and Little, 1998) production operations-inventory production control, purchasing with production planning, Capacity Planning and Master Scheduling (Turbide, 1990) sales, logistics, production, engineering and funding functions, the broad ingredients of almost all Manufacturing organization (Ip and Yam, 1998). It may also include costumer service- order entry, sales analysis, forecasting- with financial applications. The total is a single information control system that shares data among the various applications for the mutual benefit (Turbide, 1990). MRP II operates in a pull manner at the planning level. It is used for high-level planning of demand and inventory functions and preliminary capacity evaluations.Ip and Yam (1998) afford a master plan which in tegrates the technology and management of the strategic elements, problem definition, MRP II solutions, technical and procedural design, and implementation management in order to minimize the frustration and conflicts universally found in MRP II implementation process as well as to reduce disconnection amongst different stages of the implementation process.Ideally MRP II addresses operational planning in units financial planning in money terms, and has simulation capability to answer what-if questions. It is made up of a variety of functions, each linked together business planning, production planning, master production scheduling, material requirements planning, capacity requirements planning and the execution systems for capacity and priority. Outputs from these systems would be integrated with financial reports, such as the business plan, purchase commitment report, chipping budget, inventory production in money terms, etc. Manufacturing Resource Planning is a direct outgrowth an d extension of a Material Resource Planning (MRP) (Higgins et al., 1998).3.1.2.1 MRP II definitionsIf I had to sum up MRP II in one word, the word I would choose is discipline. Allowed three words, they would be discipline/performance measurement Sheldon (1991). He detailed the total implementation process, from inception to completion and divided the process into six steps, namely, education, common goal, fitness for use, accountability, performance measurement and systems/tools. In Table 3.1, the definition of MRP II is summarized.Table 3.1 Definition of MRP IIDefinitionReferenceMRP II is a well-defined process or set of calculations that is used to develop plans for the acquisition of the materials needed for production.(Turbide, 1990)MRP II is an information control philosophy that is often translated into software products containing, among other capabilities the MRP calculation function.MRP II is a system designed for managing all the resources of a manufacturing company. It consists of a comprehensive set of planning tools and techniques which integrate all functional areas of an organization(Tremblay, 1991)MRP II is a method for the effective planning of all resources of a manufacturing company.(Dougherty and Wallace, 1992)Manufacturing resource planning (MRP II) is a long promising method that simplifies all the complex tasks of manufacturing management.(Chambers, 1996)MRP II is a hierarchically structured information system which is based on the idea of controlling all flows of materials and goods by integrating the plans of sales, finance and operations.(Zapfel, 1996)Manufacturing Resource Planning (MRP II) is a structured approach to optimize a companys internal Supply Chain.(Higgins et al., 1998)MRP II is a method for the effective planning of all resources of the manufacturing company.MRP II is an effective management system that has excellent planning and scheduling capability which can offer dramatic increases in customer service, significant gains in productivity, much higher inventory turns, and greater reduction in material costs.(Ip and Yam, 1998)MRP II system is a proactive materials strategy. It is a dynamic system and can adapt to change as it reflects upon the latest information in its planned order releases.(Towers et al., 2005)3.1.2.2 MRP II benefitsThe potential benefits those may receive from the MRP II are summarized belowEmpirical research suggests that companies able to implement MRP II successfully report enhanced competitive positions, improved customer service levels, a better financial position, increased plant efficiency, heightened morale in production, more effective co-ordination with marketing and finance, more efficient production scheduling and reduced inventory levels, fewer component shortages, reduced manufacturing costs and lead times and improvements in inventory turnover (Humphreys et al., 2001, Brown and Roberts, 1992, Roberts and Barrar, 1992).When customers and suppliers (internal or ex ternal) request information that have been fully integrated throughout the Supply Chain or when executives require integrated strategies and tactics in areas such as manufacturing, inventory, procurement and accounting, MRP II systems collate the data for analysis and transform the data into useful information that companies can use to support business decision-making (Broatch, 2001).MRP II systems, if implemented successfully, enhance and redesign business processes to eliminate non-value-added activities and allow companies to focus on core and truly value-added activities (Broatch, 2001).The focus of MRP II computer systems is on the efficiency and effectiveness of the internal processes. It offers a way to streamline and align business processes, increase operational and manufacturing efficiencies and bring order out of chaos (Nah, 2002).MRP II systems minimize the time and effort required to process business data and maximizes the application of that information. By facilitatin g data exchange throughout the organization, a MRP II system enables to coordinate such crucial activities as production planning, material planning, capacity planning and shop floor control (Plenert, 1999).MRP II is concerned mainly with scheduling of activities and the management of inventories. It is particularly useful where there is a need to produce components, items or sub-assemblies, which themselves are later used in the production of a final product. Organizations can improve their overall customer service through consistently meeting delivery promises, shortening delivery times and having products on hand when customer orders are received. MRP II can provide the necessary management information to ensure delivery promises can be kept. Where there is volatility in demand with unpredictable customer requirements and complex product structures, the information management capability of MRP II is particularly relevant (Towers et al., 2005).A well implemented MRP II system can provide an organization with reliable lead times meet its service delivery performance requirements contribute to stable and consistent lead times and well informed decision-making maintain lower level of safety stock reduce the average inventory level and reduce inventory investments to a minimum (Towers et al., 2005).The uncertainty of demand can be minimized due to the fact that MRP II can provide an organization with a clear picture of the demand for a particular item and when organizations know their future needs they can negotiate their purchase agreements with suppliers and receive quantity discounts improving their financial position (Towers et al., 2005).Successful MRP II users have typically reported as much as 15 percent gain in manufacturing productivity, 50 percent reduction in overtime, 33 percent reduction in inventory investment and 80 percent reduction in inventory shortages (Towers et al., 2005). MRP II provides better control over the quantity and timing of delive ries of raw materials, parts, sub-assemblies and assemblies to production operations.3.1.2.3 Pitfalls of MRP IIThe main pitfalls of MRP II from various authenticated literature are listed belowImpressive though the benefits are, there is evidence suggesting that, as with so many similar technologies, few companies are able to maximize them.

Unsuccessful MRP II implementation not only deprives companies of potentially huge benefits but also results in financial losses and disruptions in operations (Towers et al., 2005).MRP II concept is only partially suited to production planning in the case of uncertain demand. There is little help with the necessary aggregation and disaggregation process, especially when demand uncertainty exists. It is difficult for the user of MRP II to find a robust aggregate pl an for master production schedule (Zapfel, 1996).Critics of MRP II points to the rigidity of the process the logic that demands batches and multiple the fixed lead time which takes no account of current capacity the standard queue concept in front of a work center etc. Increasing competitive pressure, manifested by reduced lead times, smaller batch sizes, lower stocks and ever more demanding customers have pushed MRP II to its limits (Porter et al., 1996).3.1.2.4 Reasons for failureOne of the principal reasons for the failure of MRP II and other large technologically sophisticated systems is that organizations simply underestimate the extent to which they have to change in order to assimilate what is in reality a new way of running the company (Humphreys et al., 2001).MRP II failure have embraced technical problems the difficulties involved in selecting and evaluating cost effective MRP II packages and a host of historical, cultural, structural and managerial issues (White, 1980, Ki nnie et al., 1992, Wight, 1990, Wilson et al., 1994) expertise needed to implement and use effective MRP II systems lead times management design of the production environment, routing and quality information Infinite capacity availability batch and lot sizing (Higgins et al., 1998).An accurate demand forecast is an essential foundation for the successful operation of an MRP II system. Poor sales forecasting had been identified by senior management as one of the main reasons for the MRP II implementation failure (Humphreys et al., 2001).3.1.3 Enterprise Resource Planning (ERP)The Gartner Group of Stamford, CT, USA, coined the term ERP in the early 1970s to describe the business software system. The name ERP was derived from the terms material requirements planning (MRP) and manufacturing resource planning (MRP II). The maturity stage of ERP occurred in the mid-1990s. ERP is the third generation of planning software. Material requirements planning (MRP) was the first generation, manuf acturing resource planning (MRP II) the second and ERP the third. The primary purpose of ERP is to create a seamless integration of interrelated information throughout the business organization. A system of software programs is used to develop the necessary links between the various business functions so that needed information is readily available. There are 8 (eight) major functions and 33 (thirty three) sub-functions, as well as 22 (twenty two) primary modules and several sub-modules (Umble et al., 2001). A typical ERP implementation takes anywhere from one to five years (Mabert et al., 2003). ERP system is not just a pure software package to be tailored to an organization but an organizational infrastructure that affects how people work and that it imposes its own logic on a companys strategy, organization, and culture (Shehab et al., 2004, Davenport, 1998, Lee and Lee, 2000).3.1.3.1 Definition of ERPWhen customers and suppliers request information that have been fully integrate d throughout the value chain or when executives require integrated strategies and tactics in areas such as manufacturing, inventory, procurement and accounting, ERP systems collect the data for analysis and transform the data into useful information that companies can use to support business decision-making. They allow companies to focus on core and truly value-added activities (Nah, 2002). These activities cover accounting and financial management, human resources management, manufacturing and logistics, sales and marketing, and customer relationship management. Table 3.2 shows definitions of ERP, cited in different literatures.Table 3.2 Definition of ERPDefinitionReferenceERP systems are enterprise-wide on-line interactive systems that support cross-functional processes using a common database. ERP systems are designed to provide, at least in theory, seamless integration of processes across functional areas with improved workflow, standardization of various business practices, and access to real-time up-to-date data.(Davenport, 1998)ERP systems are complex and implementing one can be a challenging, time consuming and expensive project for any company.ERP is not only an IT solution, but also a strategic business solution. As an IT solution, ERP system, if implemented fully across an entire enterprise, connects various components of the enterprise through a logical transmission and sharing of data.(Norris et al., 2000)ERP is a commodity, a product in the form of computer software.(Klaus et al., 2000)ERP is a development objective of mapping all processes and data of an enterprise into a comprehensive integrative structure.ERP is a key element of an infrastructure that delivers a solution to business.ERP a method for the effective planning and controlling of all the resources needed to take, make, ship and account for customer orders in a manufacturing, distribution or service company.(Nah, 2002)ERP system is a packaged business software system that allows a co mpany to automate and integrate the majority of its business processes, and share common data and practices across the entire enterprise.(Seddon et al., 2003)ERP is a do it all system that performs everything from entry of sales orders to customer service. It attempts to integrate the suppliers and customers with the manufacturing environment of the organization.(Shehab et al., 2004)3.1.3.2 Benefits of ERPERP systems have certain advantages such as low operating cost and improving customer service (Shehab et al., 2004). In implementing an ERP solution, an organization can quickly upgrade its business processes to industry standards, taking advantage of the many years of business systems reengineering and integration experience of the major ERP vendors (Myerson, 2002). The practical benefits of ERP are divided into five aspects by Seddon et al. (2003) operational, managerial, strategic, IT infrastructure, and organizational (Table 3.3).Table 3.3 Benefits of ERPOperational benefitsBy automating business processes and enabling process changes, they can offer benefits in terms of cost reduction, cycle term reduction, productivity improvement, quality improvement, and improved customer service.Managerial benefitsWith centralized database and built-in data analysis capabilities, they can help an organization achieve better resource management, improved decision making and planning, and performance improvement.Strategic benefitsWith large-scale business involvement and internal/external integration capabilities, they can assist in business growth, alliance, innovation, cost, differentiation, and external linkages.IT infrastructure benefitsWith integrated and standard application architecture, they support business flexibility, reduced IT cost and marginal cost of business units IT, and increased capability for quick implementation of new applications.Organizational benefitsThey affect the growth of organizational capabilities by supporting organization structure chan ge, facilitating employee learning, empowering workers, and building common visions.3.1.3.3 Disadvantages of ERPERP systems have some disadvantages due to the tight integration of application modules and data. Huge storage needs, networking requirements and training overheads are frequently mentioned ERP problems. However, the scale of business process re-engineering (BPR) and customizations tasks involved in the software implementation process are the major reasons for ERP dissatisfaction. ERP projects are large, costly and difficult and that they require large investment in capital and staff and management time (Adam and ODoherty, 2000). Yen et al. (2002) identified the following disadvantages of ERPIts high cost prevents small businesses from setting up an ERP systemThe privacy concern within an ERP systemLack of trained people may affect ERPs efficiencyImplementation of an ERP project is painfulCustomization is costly and time-consuming.Some of these shortcomings have been discu ssed by OConnor and Dodd (2000). Implementation of an ERP system is an extensive, lengthy and costly process, typically measured in millions of dollars. An ERP implementation can take many years to be completed and cost tens of millions of dollars for a moderate size firm and upwards of $100 million for large international organizations (Mabert et al., 2000). Even with significant investments in time and resources, there is no guarantee of a successful outcome (Mabert et al., 2003). According to Shehab et al. (2004), the ERP systems are complex and implementing one can be difficult, time-consuming and expensive project for a company. It costs tens of millions of dollar for a medium sized company and $300-500 million for large international corporations. There are also some possible hidden costs that may include losing some very intelligent employees after the initial implementation is done, continual imp
