Critical Review for the Article Essay Example for Free

Basic Review for the Article Essay The electronic diary entitled: ‘The Long-Term Performance of Horizontal Acquisition’, by Laurence Capron of the Institut Europeen dAdministration des Affaires (INSEAD), distributed in 1999 by the Wiley and Sons distributing, has considered the formation of â€Å"horizontal mergers and acquisition†. In Capron’s paper, he dated his investigations from mid-1980’s to mid 1990’s financing techniques of firms in stripping and exchanging its benefits which he alluded as the â€Å"horizontal mergers and acquisition†. Capron has refered to around 253 firms in Europe and America that designs the financing techniques. As per Capron (1999), assessment uncovers divestment of benefits and capital imbuement (re-financing of exchanged resources) makes compelling to â€Å"acquisition performance†, however could have conceivably inconvenient effect. As what Capron underlined on the presentation of procurement dependent on â€Å"divestment and redeployment (re-obtaining) of resources†, his examination looks at the imperfections and praises on successful methods in â€Å"horizontal mergers and acquisition†. Key focuses and method of reasoning As surveyed from the diary, the â€Å"horizontal acquisitions† might be exemplified as a methods and system in building up the asset divestment conspire, in which thusly, it â€Å"optimizes or misuses the estimations of cost-based and income based synergies† (Capron 1999: p. 988). As clarified, it might be seen that the â€Å"synergy† designs the proceeding with securing of business esteems, because of divestment wherein converging of the recently differentiated firm or business esteems gains more resources and capital financial plan. As per Capron (1999), the cost effectiveness hypothesis accentuates on the importance of cost-based cooperative energies that happen when resources have been stripped coming about the coordination of cost-sparing measures. In this manner, the firm performs successfully in upgrading its incomes that synergizes with the redistribution of the capital towards an improved ability. It might be broke down from the discoveries of Capron that the 1980’s and 1990’s quick development of businesses achieved by globalization have risen more interests in the gracefully chain. One of which is the situating of created and very good quality businesses inside crude material sources. Like, for instance, broadening process has been created in Asian nations wherein greater interest in modest crude materials and work are accessible and can be procured without any problem. The â€Å"horizontal acquisition† could be drawn from setting up organization, auxiliary in activity, joint endeavors and between reliance in fare and import plans. Thus, for instance â€Å"Company A† has stripped in setting up â€Å"Company B† to take part in tire fabricating that source out the least expensive crude materials. In which case, a differentiated mechanical firm could wander out into â€Å"versatile† business esteems that advance capital speculations for a bigger income age converted into cost adequacy that implies significant benefit. In Capron’s finding, the alleged â€Å"economy of scale† turned into the bases of enhancement process that made ready to a â€Å"large-scale† industrialization. The twentieth century practice of the economy of scale has supported more businesses to catch the â€Å"investment areas†, explicitly in poor nations. The â€Å"dispensation of merging† through open-finished stockholding in little medium-enormous endeavors units has placed noteworthy importance in getting modern association, wherein capital speculation has a basic job in consolidating organizations. As refered to from Capron’s discoveries, the intelligent financial clarification is catching income based cooperative energies which are ordinarily recognized as assigning and supplementing assets by giving â€Å"core competencies† or â€Å"mobilizing undetectable assets† (Penrose 1959; in Capron 1999: p. 989). As refered to, Capron likewise brought up in his â€Å"theoretical model† of post-obtaining and target redeployment (Capron 1999: pp. 990-995). As per Capron, the hypothesis portrays the enhancement procedure as concentrating on (1) resource divestiture, (2) cost-sparing, (3) asset redeployment, and (4) income upgrading capacities as a viable methods for â€Å"acquisition performance† (Capron 1999: p. 992). The hypothetical model alludes to and clarifies the â€Å"basic financial behavior† as delineated in the procurement execution. Capron further guessed that capacities in a stripped firm are being disseminated as an authoritative endeavor. Which means, it tends to be clarified that the arrangement of corporate administration and HR are conveyed or being shared that creates the securing execution. In any case, key â€Å"organic elements† were accentuated to have been incorporated in the divestment procedure, in which the re-arrangement (or sending) of the hierarchical â€Å"system or setting† are procured. End Capron’s assessment on the flat procurement and projection of model in key post-obtaining and redeployment could be comprehended as a principal undertaking in broadening process. The facts may prove that the majority of blending firms in their obtained resources or business are chiefly disseminating their in-put â€Å"organizational or corporate system†. In any case, the consolidating firms could in like manner upgrade or â€Å"streamline the current authoritative set-up, which is the basic event in many firms that attempted a â€Å"buy-out†. It might be seen that the income age could be generally gained into alternatives by smoothing out the current hierarchical set-up or re-sorting out both human and capital assets. Capron’s discoveries have underscored more on the exhibition ability on the hypothesis of â€Å"horizontal acquisition† alluding just to capital financial plan, as inferred on the capital assets or fixed resources of the organizations. The human asset angle [as a basic unit] of the post-procurement procedure may have not been all around stressed. What has been for the most part examined in the examination is the transformative business esteem in divestment plans alluding to capital ventures and fixed resource liquidation. It could be mirrored that the capital speculation and fixed resource liquidation are the basic factors in the divestment conspires as the essential asset of consolidating partner. It could be proposed that the â€Å"potentially inconvenient impact† [as additionally brought up by Capron] could be alluded to the HR or work power in a differentiated industry. The combining partner in Capron’s discoveries were greatly given pertinence on how they could adequately act in focusing on their post-obtaining and redeployment, in which the examination itself imagines to supplement the presentation abilities of the partners. Now, we may reevaluate Capron’s â€Å"theoretical model† as giving more â€Å"weight† to the imagining of transnational and worldwide endeavors in promotion of globalization, wherein the proceeding with divestment plot contends in the huge scope economy of work market and capital develop. We may then infer that Capron’s discoveries could be reconsidered with further examinations identifying with HR re-sending or organization on its even advancement supplementing the enhancement of ventures, where the parallelism imagines both human and capital divestment. Segment B Morrison’s offer to Safeway The electronic magazine of the Financial Times on its December eighth 2003 issue at the www. ft. com site has distributed the news story of Richard Milne entitled: ‘Countdown Starts for Morrisons Bid for Safeway’. As per the news story, the Morrison Supermarket awaited 21 days from its rivals, for example, Tesco, J. Sainsbury and Asda-WalMart, following the UK government’s offer to sell the Safeway market. The UK Department of Trade and Industry uncovered that â€Å"Morrison was eager to sell its 53 stores if securing of Safeway is successful† (Richard Milne 2003; in Ft. com 2008). Morrison’s arrangement was supported by the UK Competition Commission that excluded the three significant contenders from the offering and maintained Morrison to takeover Safeway with a portion of 219-1/2 from the 279-1/2, in which Safeway recognized the purchase out. In a subsequent report in 2004, following a time of the purchase out, the Safeway has increased 40% of deals development. Money related examiners guaranteed that Safeway has â€Å"migrated customers† to Morrison store, as it refered to that â€Å"quality of deals has gone better since Morrison has halted the Safeway strategy of moving profound discounts† (Martin Dickson 2004; in Ft. com 2008). Impression of the issue Morrison’s takeover of Safeway grocery store has measured the circumstance of noteworthy monetary divestment adventure. The business possibilities of Safeway [being a built up grocery store that exclusively contends with Tesco, J. Sainsbury and Asda-WalMart] were the â€Å"strong intent† of monetary divestment of Morrison to considerably offer the sell of its 53 stores. The monetary divestment of Morrison could be relating Capron’s discoveries on the â€Å"horizontal acquisition† of consolidating partners by method of capital speculations through broadened resources. In which case, the Safeway grocery store has found by Morrison as a â€Å"potential divestiture† that will ingest the defenselessness from intense contenders. The converging of partner through a purchase out or takeover of a built up venture [like Safeway] may have approved Capron’s hypothesis of â€Å"post-procurement and redeployment†, in wh

Nazism And World War II Essays - Adolf Hitler, Nazi Germany

Nazism And World War II Essays - Adolf Hitler, Nazi Germany Nazism and World War II The National Socialist German Workers? Gathering nearly passed on one morning in 1919. It numbered just two or three dozen complainers? it had no association and no political thoughts. Be that as it may, numerous among the working class respected the Nazis? solid restriction to the Social Democrats. Furthermore, the Nazis subjects of energy and militarism drew profoundly enthusiastic reactions from individuals who couldn't overlook Germany?s prewar supreme greatness. In the national appointment of September 1930, the Nazis gathered about 6.5 million votes and turned out to be second just to the Social Democrats as the most well known gathering in Germany. In Northeim, where in 1928 Nazi applicants had gotten 123 votes, they currently surveyed 1,742, a decent 28 percent of the aggregate. The across the country achievement drew even quicker... in only three years, party enrollment would ascend from about 100,000 to very nearly a million, and the quantity of neighborhood offices would increment ten times. The new individuals included common laborers individuals, ranchers, and working class experts. They were both better taught and more youthful then the Old Fighters, who had been the spine of the gathering during its first decade. The Nazis currently introduced themselves as the gathering of the youthful, the solid, and the unadulterated, in restriction to a foundation populated by the old, the powerless, and the lewd. Hitler was conceived in an unassuming community in Austria in 1889. As a little fellow, he demonstrated little desire. Subsequent to dropping out of high school, he moved to Vienna to consider workmanship, however he was denied the opportunity to join Vienna foundation of expressive arts. When WWI broke out, Hitler joined Kaiser Wilhelmer?s armed force as a Corporal. He was not an individual critical. He was an animal of a Germany made by WWI, and his conduct was molded by that war furthermore, its results. He had risen up out of Austria with numerous partialities, including a ground-breaking bias against Jews. Once more, he was a result of his occasions... for some Austrians and Germans were partial against the Jews. For Hitler's situation the partiality had become deranged it was a predominant power in his private and political characters. Hostile to Semitism was not an arrangement for Adolf Hitlerit was religion. Furthermore, in the Germany of the 1920s, staggered by rout, and the attacks of the Versailles settlement, it was not difficult for a pioneer to persuade millions that one component of the nation?s society was liable for a large portion of the wrongs loaded upon it. The truth of the matter is that Hitler?s hostile to Semitism was self-dispensed deterrent to his political achievement. The Jews, as other Germans, were stunned by the disclosure that the war had not been battled to an ezdstill, as they were persuaded in November 1918, however, that Germany had , indeed, been crushed and was to be treated as a vanquished nation. Had Hitler not set out on his approach of disestablishing the Jews as Germans, and later of killing them in Europe, he could have depended on their devotion. There is no explanation to think whatever else. On the night of November 8, 1923, Wyuke Vavaruab State Cinnussuiber Gustav Rutter von Kahr was making a political discourse in Munich?s rambling B?rgerbr?ukeller, about 600 Nazis and conservative supporters encompassed the brew lobby. Hitler burst into the structure and jumped onto a table, wielding a gun and shooting a fired into the roof. ?The National Upheaval,? he cried, ?has started!? By then, educated that battling had broken out in another piece of the city, Hitler hurried to that scene. His detainees were permitted to leave, and they discussed sorting out protections against the Nazi overthrow. Hitler was obviously angry. What's more, he was a long way from wrapped up. At around 11 o?clock on the morning of November 9the commemoration of the establishing of the German Republic in 19193,000 Hitler partisans again accumulated outside the B?rgerbr?ukeller. Right up 'til today, nobody realizes who discharged the main shot. In any case, a shot rang out, and it was trailed by fusillades from the two sides. Hermann G?ring fell injured in the thigh and the two legs. Hitler straightened himself against the asphalt; he was safe. General Ludenorff kept on walking indifferently toward the police line, which separated to let him go through (he was later captured, attempted and vindicated). Behind

Does a Late Rent Payment Affect Your Credit

Does a Late Rent Payment Affect Your Credit Does a Late Rent Payment Affect Your Credit? Does a Late Rent Payment Affect Your Credit?Paying rent at the same time each month can be a challenge, especially if your payday schedule doesnt align with your landlords due date.Rent is usually a top priority bill for people to pay each month. If the rent isn’t paid, they are taking a chance at not having a roof over their heads for much longer.Unfortunately, our paycheck schedules don’t always align with the date that rent is due. If your paycheck simply doesn’t come in until the third of the month and rent is due on the first, sometimes it’s just going to be late. Many people would rather not have to deal with taking out a risky payday loan to get through those few days.Sometimes people get into tighter situations â€" if an emergency medical bill or some other unexpected expense comes up, people can find themselves behind on rent payments by a month or more, putting their housing, and possibly credit, at risk.Do landlords report late rent?The short answer: not always. It ’s generally optional for landlords to report late rent. And in order for them to report late rent themselves, they generally need to be a member of a credit reporting bureau, which include Equifax, Experian, and TransUnion. Because of this, it’s not that common for late rent to appear on credit scores. If you want to be sure, you can go ahead and ask your individual landlord if they do report late rent payments. It’s possible many will say no or say they don’t report them unless late payments are a consistent problem or extremely late. Landlords are people too, so they may react differently in different situations.There are, however, some caveats to note: If your landlord uses certain kinds of rent payment services, they may automatically report rent to credit bureaus as part of the service. If you need more information about this, this article by Experian has a list of several payment services that offer a credit reporting service.You’re also more likely to be vulnerable to your landlord reporting late rent if you’re renting from a property management company or another corporate entity. They might have their own policies they follow regarding late rent without taking individual situations into account.It’s important to note that if you build up debt with a landlord and the debt is sold to a collection agency, the debt will then appear on your credit report, even if the landlord didn’t previously report your payments. A large amount of debt appearing at once could be a major ding to your credit score.Another important note: Payments should typically be 30 days late before they are reported, so even if you’re perpetually getting in rent just a couple days late, all you may have to worry about is a few late fees and an irritated landlord â€" although a situation like that is not going to help your cash flow or your landlord’s willingness to be flexible to your situation. Contact your landlord about their reporting policies to know for sure. How much will a late rent payment ding my score?It depends. It’s important to remember that recent late payments affect credit scores the most. Since payment history is a whopping 35% of your credit score, according to FICO, it can have a pretty dramatic impact. However, it’s not anything you can’t recover from with time and timely payments.It’s important to keep in mind the other consequences of your rental history being made public. Landlords tend to run a credit check before renting to someone. Therefore, if you’ve had previous landlords report your late payments to the credit bureaus, as this rental website article discusses, they will see your past rental payment history. Even if you have an otherwise positive credit score, they might decide to turn you down in favor of someone who has always paid rent on time.There are various ways late rent payments may be reported. For the most accurate prediction on whether yours will be reported, contact your landlord or property management company.Paying rent can positively affect your credit, tooThere is a positive side to all this: If your rent payments are being reported, then paying rent on time can be a great tool for helping you build up your credit. Remember: With credit, it goes both ways.Have more questions regarding rent and its impact on your credit or cash flow?

What is an Essay Are You Sure You Know the Answer

Any modern student encounters the question of what is an essay during his/her course of education sooner or later. Usually, this happens in a form of an assignment that the teacher, professor, or any other tutoring staff provides. It is a basic type of academic work that aims to test the student’s both creative and analytical thinking skills and evaluate his/her ability to apply them in a written form. An essay is first of all about expressing one’s opinion or idea about a specific topic and doing so on paper. In order to be able to conduct this form of creative writing, it would be reasonable for one to attempt to define exactly what is an essay. Essay as a Written Thought One may find difficulties in seeking the exact definition of what is an essay, however, it could be said for sure that it is a way of expressing the author’s thoughts. While there is no universal definition that would set this type of work within the boundaries of a set of rules, this characteristic clearly resembles its loose nature. One can describe an essay as a short story, a report, a research paper, a journal, or even a media blog article. The beauty of an essay lies in the fact that it can be all of the above, even at the same time. What Types of an Essay are There? An essay can take up numerous forms. One of the most recognizable is the academic essay – a short paper, usually 2-3 pages long, which is written as an academic assignment, in order to evaluate the gained knowledge of the student. Some teachers prefer to set fixed criteria for their essays, while some provide the freedom to express one’s opinion on the matter. It all comes down to the educational approach of each tutor. An essay can also take form of a journal review, book summary, self-assessment, movie critique, play analysis, history paper, and many others. What is the Structure of an Essay? The common academic essay in most cases is built from three main elements: the introduction, the body, and the conclusion. The introduction is a small paragraph that consists of a summary describing the main theme of what the essay is about. It starts with a hook, designed to catch the attention of the reader, and ends with a thesis that sets the main topic. The body is the main part that consists of most of the text, and the conclusion is a summary which is similar to the introduction, although different in the way it attempts to outline what was gained as a result of the conducted work or research. Why Write an Essay? The answers may quite differ, as they are plenty. An essay is commonly chosen as an academic assignment since it allows the student not only to learn how to collect thoughts and knowledge, but to chain them together in a form of creative writing. It is a unique practice that is capable of stimulating one’s both creative and analytical thinking. However, the best part about writing an essay is that the process can be quite enjoyable for the writer him/herself, and can even pass on this joy further to the reader.

Leadership Style Of The Company Essay - 1986 Words

Most companies and organizations have members of their senior executives that take on more than their role as an executive but are also the organizational leader for the company.

For many people college is the first time where they are away from the home for the first and must make new friends. College students are particularly susceptible to developing issues because of how exciting this new time is in one person’s life. For these young adults, the new independence, increased workload, homesickness, and desire to succeed in their new surroundings puts unsolicited pressure on them that they have never experienced before. Suddenly, the pressure of having a slim hourglass figure, perfectly styled hair, and impeccably manicured nails are influential in ways that one may not have thought before. The stigma with college students and their eating habits is that most people eat a diet filled with ramen noodles, microwaveable dinners, and excessive amounts of coffee.

Is Race a Natural Kind - Free Essay Example

Sample details Pages: 5 Words: 1610 Downloads: 4 Date added: 2018/12/18 Category Science Essay Type Research paper Level High school Did you like this example? Introduction Natural kind forms a scientific discipline that is frequently divided to derive the actual meaning. Majorly, the scientific study offers two perceptive, one that entails the naturalness of a kind and the kindhood. The naturalness of a kind tries to establish whether the naturalness of a kind is what makes it natural. Don’t waste time! Our writers will create an original "Is Race a Natural Kind?" essay for you Create order On the other hand, the kindhood offers a different understanding in that it entails finding out whether the components that make up a thing is what makes it natural (Porcher 2016, 212). However, in consideration of both studies, the naturalness of an element corresponds to the structure of the natural environment, and not on the human interests and actions. Therefore, it is by logical assumption that science has succeeded in revealing all the natural occurrences whereas the classification and the taxonomies are all by scientific realism. As a result, psychology can easily reverse on the kinds that it holds as natural. Therefore, there is a significant connectedness between the study of natural kinds and realism. The realistic position on natural kinds In this regard, realism refers to the view of the existence of entities in natural kinds. On the other hand, naturalism refers to the presence of natural groupings with distinctions among them. Therefore, naturalism has no ontological commitment while realism is an ontologically committed type of view. Notably, the realistic position maintains on the fact that it is not possible to explain the differences between the natural and the non-natural groupings without considering entities in natural kinds. (Franklin-Hall and Laura 2015, 928) Different theories on natural kinds exist and efficiently compete to offer a well-developed concept. Firstly, the cluster of natural kinds is usually developed according to similar objectives and common properties which form a single group. It is challenging to determine a natural kind in realism as opposed to conventional. Therefore, a suitable way to draw an appropriate distinction is through the similarities and the standard features while the later majorly depends on the human interests. Secondly, natural kinds are believed to have essences. According to (Magnus 2015, 7), essence refers to a membership-determining a given property which is not only necessary but also sufficient enough to belong to a specific group. However, the theories fail to agree on the way essential characteristics in a kind. Whereas, the fundamental properties are responsible for other features associated with the type. For instance, having an atomic number 79 makes something a member of a particular group. However, there are other properties regarding color, mass and density. Phenotypical features are sufficient to pick out a natural kind Evidently, contemporary philosophers in the field of biology held for the longest time that biological species are insufficient to be regarded as natural kinds. However, organic features, for instance, phenotypical features are sufficient enough to pick out a natural kind (Marti ­nez 2015, 99). As a result, incorporation of biological characteristics in natural kind offers an in-depth understanding of natural kinds. Notably, it provides that natural kind involves the cases of spatiotemporally of which are not accidental and resemble each other to form a whole species. Majorly, the controversy regarding the biological aspect and the natural kind occurs due to lack of documentation of any limitation concerning the point in place and time where the natural kind happened. However, instances of any natural kind could occur anywhere and at any time. Therefore, a biological perspective of the natural kind offers a standardized characterization. It defines the natural sort as a collection of objects or individuals with similar properties non-accidentally clustered together. Evidently, biological species are also natural kinds. For any organic classification, there is a plurality of traits, phenotypic or genotypic. The attributes play a critical role individually and collectively (Kidwell and Kimberlee, et al. 2015, 29). As a result, their input in such a species is necessary and sufficient. It universally agreed that phenotypic traits are natural kinds. However, one reason that claims it unreasonable is the dimorphism. Notably, in every species, there are abnormal or aberrant members who phenotypic traits are the actual reflection of confined genotypic variations. Indeed, it is evident that biological species are among the natural kinds. Their instances happen to be scattered in space and in time, therefore a typical example in which a collection of cases join together to develop one common reason. A substitute for what picks out the natural kind The similarity relations majorly determine the spontaneous nature. The connections, however, have been defined differently based on their branch of science. For instance, the subject will establish the similarity based on the field they operate. Notably, biology is expected to identify the similarities between the organisms found in the genealogical information or common genes. Therefore, apart from phenotypical classification, the similarities can be reduced to an allele (1000 Genomes Project Consortium 2015, 70). In this regard, some organisms will be more genetically similar. This would drop out resemblance as a genetic concept to a more specific notion; determine the similarity in molecules and genes. Evidently, any similarity between the constituents conforms to the idea of the natural kind. In this regard, nature kind classification based on the allele or the genetic concepts enables appropriate classification. Additionally, it allows getting rid of the many paradigms in the natural kinds which do not count as physical kinds. For instance, the private allele in Native Americans is a pattern in the population genetics natural kind. However, an individual allele offers uniqueness in one of the populations from the entire selection of communities. Therefore, the presence of the Native American society determines the existence of the private allele. Provide at least one objection to the realist position The realistic stand has been for the longest time suffered a complaint from the anti-realist. The antirealism holds a contradicting view in stipulating that theories are untrue and the majority ought to be disregarded. Evidently, the realistic position provides that oak is a natural kind, while a table is not. Therefore, whenever the question to determine what makes natural and non-natural nature, then no answer. As a result, it has proven challenging to develop responses to so, vital clues regarding the natural kind. Currently, developing the answers to the simple questions is yet to be achieved. According to Ludwig (2017, 35), he has given up on the term natural since so far; there is nothing like natural. According to antirealist, they consider that realists generalize all classes of natural kinds and capture a general philosophical advantage of natural kinds. Additionally, they attract natural types in such a manner that they avoid metaphysics. Notably, some of the most significant theories, for instance, Newtons laws have been proved wrong. Additionally, Darwins natural selection and relativity by Einstein still need some modification and develop some adaptation to make them appropriate (Garci ­a del Muro Navarro 2017, 29). Therefore, antirealists strongly believe that theories are merely tools of which people use after being approved to be wrong. According to antirealists, most of what them think to be the cause of the world based on the minds ability to create precise features or offer characteristics on what they perceive. Why realism about race is better than conventionalism Notably, there nothing in particular that makes a natural kind natural. However, some philosophers have denied this assumption and insisted that a natural kind is relative to a specific inquiry. Therefore, race lacks any biological contradictions between members of other races (Winther 2014, 215). As a result, it may be untrue to conclude that race is not a natural kind. Realism refers to that position attributed to positive ontological status. So when one is a realist about the race, that means the race is real and contains several physical attributes. On the other hand, conventionalist is not constant. Humans are not genetically grounded, however; they usually form due to social practices. Hence, races are adopted based on some broad genetic dissimilarity among some populations. Moreover, the color creates only an outward manifestation. As a result, the realism stand about race is more convincing unlike conventionalism. In conclusion, natural kind forms a scientific discipline that is frequently divided to derive the actual meaning. Majorly, the scientific study offers two perceptive, one that entails the naturalness of a kind and the kindhood. Notably, the realistic position on natural kinds provides that it is not possible to explain the differences between the natural and the non-natural groupings without considering entities in natural kinds. Therefore, a suitable way to draw an appropriate distinction is through the similarities and the standard features. Moreover, phenotypical features are sufficient enough to pick out a natural kind. As a result, incorporation of biological characteristics in natural kind offers an in-depth understanding of natural kinds. Nature kind classification based on the allele or the genetic concepts enables appropriate classification offer a suitable substitute what picks natural kind. Majorly, anti-realist offers the major objection to realist and consider majority of the theories as untrue. However, when one is a realist about the race, that means the race is real and contains several physical attributes. Works Cited 1000 Genomes Project Consortium.

Three forecasting models, namely, Winter’s, decomposition, and Auto-Regressive Integrated Moving Average (ARIMA), are applied to forecast the product demands. The results are compared with those obtained by subjective and intuitive judgements (which is the current practice). It is found that the decomposition and ARIMA models provide lower forecast errors in all product groups. As a result, the safety stock calculated based on the errors of these two models is considerably less than that of the current practice. The forecasted demand and safety stock are subsequently used as inputs to determine the production plan that minimizes the total overtime and inventory holding costs based on a fixed workforce level and an available overtime. The production planning problem is formulated as a linear programming model whose decision variables include production quantities, inventory levels, and overtime requirements. The results reveal that the total costs could be reduced by 13. % when appropriate forecasting models are applied in place of the current practice. KEYWORDS: demand forecasting, highly seasonal demand, ARIMA method, production planning, linear programming, pressure container factory. INTRODUCTION Most manufacturing companies in developing countries determine product demand forecasts and production plans using subjective and intuitive judgments. This may be one factor that leads to production inefficiency. An accuracy of the demand forecast significantly affects safety stock and inventory levels, inventory holding costs, and customer service levels. When the demand is highly seasonal, it is unlikely that an accurate forecast can be obtained without the use of an appropriate forecasting model. The demand forecast is one among several critical inputs of a production planning process. When the forecast is inaccurate, the obtained production plan will be unreliable, and may result in over- or understock problems. To avoid them, a suitable amount of safety stock must be provided, which requires additional investment in inventory and results in an increased inventory holding costs. In order to solve the above-mentioned problems, systematic demand forecasting and production planning methods are proposed in this paper. A case study of a pressure container factory in Thailand is presented to demonstrate how the methods can be developed and implemented. This study illustrates that an improvement of demand forecasts and a reduction of total production costs can be achieved when the systematic demand forecasting and production planning methods are applied. The demand forecasting and production planning methods are proposed in the next section. The background of the case study, including, products, production process, and the forecasting and production planning procedures being used in the factory, are briefly described in Section 3. The detailed analyses of the forecasting methods and the production planning method are explained in Section 4 and Section 5, respectively. Finally, the discussion and conclusion are presented in Section 6. 272 ScienceAsia 27 (2001) P ROPOSED D EMAND F ORECASTING PRODUCTION PLANNING METHODS AND The proposed demand forecasting and production planning methods are depicted in a step-by-step fashion in Fig. . Most factories produce a variety of products that can be categorized into product groups or families. Individual products in the same product group generally have some common characteristics. For example, they may have the same demand pattern and a relatively stable product mix. As a result, it is possible to forecast the aggregate demand of the product group first, and then disaggregate it in to the demand of individual products. Since the forecast of the aggregate demand is more accurate than that of the individual demand1, it is initially determined in Step 1. Then the demands of individual products are determined in Step 2 by multiplying the aggregate demand with the corresponding product mix that is normally known and quite constant. Since the demand forecasts are always subject to forecast errors, safety stocks are provided to avoid stock-out problems. Based on the standard deviation of the forecast errors and the required service level, the safety stocks for individual products are determined in Step 3. Production planning decisions are so complicated and important that they should not be subjectively and intuitively made. Consequently, an appropriate production planning model should be formulated to determine the optimal decisions. With this model, its parameters, eg, demand forecasts, safety stocks, holding cost, overtime cost, machine capacity, inventory capacity, and available regular time and overtime, are entered or updated (Step 4). In step 5, the optimal decisions regarding the production quantities, inventory levels, and regular production time and overtime for each product in each production stage are obtained by solving the production planning model. Step 6 indicates that only the optimal production plan of the current month will be implemented. After one month has elapsed, the demand forecasts and the production plan will be revised (by repeating Steps 1 to 5) according to a rolling horizon concept. BACKGROUND OF THE CASE STUDY The pressure container factory manufactures 15 products, ranging from 1. 25 to 50 kg of the capacity of pressurized gas. The products are divided into eight product groups, namely, Group 1 to Group 8. The first six groups have only two components, â€Å"head† and â€Å"bottom†, while the last two groups have three components, â€Å"head†, â€Å"bottom†, and â€Å"body†. The production process can be divided into five stages as shown in Fig. 2. Stage 3 is only required to produce the products having three components (ie, those in Groups 7 and 8). Stage 4, the circumference welding, is found to be a bottleneck stage due to its long processing time. You read "Demand Forecasting and Production Planning" in category "Papers" Presently monthly demand forecasts are subjectively determined by the Marketing Department based on past sales and expected future market conditions. No systematic method is used in forecasting. Using these forecasts and other constraints, such as availability of raw materials, equipment, and production capacity, the monthly production plan for a three-month period is intuitively determined without considering any cost factor. This results in inaccurate demand forecasts and, subsequently, an inefficient production plan.

Proposed forecasting and planning steps. Fig 2. The production process to manufacture a pressure container. ScienceAsia 27 (2001) 273 FORECASTING METHODS Steps 1, 2, and 3 of the proposed forecasting and planning process are discussed in detail in this section. Firstly, the aggregate demand forecasts of eight product groups throughout the planning horizon of 12 mont hs will be determined. Secondly, the demand forecasts of the product groups will be disaggregated into those of individual product. Thirdly, the safety stocks of individual product will be calculated based on the forecast error. Aggregate Demand Forecasts of Product Groups The typical demand pattern of each product group is seasonal. As an example, Fig. 3 shows the demand pattern of Product Group 3. Thus, three forecasting models that are suitable for making seasonal demand forecasts are considered. They are Winter’s, decomposition and Auto-Regressive Integrated Moving Average (ARIMA) models. 2-5 Because of their simplicity, the Winter’s and decomposition models are initially used to forecast the aggregate demand of each product group. If the Winter’s and decomposition models are inadequate (ie, the forecast errors are not random), the ARIMA model which is more complicated and perhaps more efficient will be applied. The Winter’s model has three smoothing parameters that significantly affect the accuracy of the forecasts. These parameters are varied at many levels using a computer program to determine a set of parameters that give the least forecast errors. There are two types of the decomposition model, namely, multiplicative and additive types. The former is selected since the demand pattern shows that the trend and seasonal components are dependent. The forecast errors of the Winter’s and decomposition models are presented in Table 1. Based on the calculated mean square error (MSE) and the mean absolute percentage error (MAPE), it is seen that the decomposition model has lower Original Series (x 1000) 16 forecast errors in all product groups than the Winter’s model. Thus, it is reasonable to conclude that the decomposition model provides better demand forecasts than the other. One way to check whether the forecasting model is adequate is to evaluate the randomness of the forecast errors. The auto-correlation coefficient functions (ACFs) of the errors from the decomposition model for several time lags at the significant level of 0. 05 of each product group are determined. The ACFs of Groups 1 and 3 are presented as examples in Fig. 4 and 5, respectively. The ACFs of Groups 4, 5, 6, 7, and 8 are similar to those of Group 1 in Table 1.

It can be seen from Fig. 4 that the ACFs of all lags are within the upper and lower limits, meaning that the errors are random. However, the ACF of lag 1 in Fig. 5 exceeds the upper limit. This indicates that auto-correlations do exist in the errors and that the errors are not random. From the ACFs, we can conclude that the decomposition model is adequate for forecasting the demands of Groups 1, 4, 5, 6, 7, and 8, but inadequate for forecasting those of Groups 2 and 3. Therefore, the ARIMA model is applied to Groups 2 and 3. From the original time series of the demand of Group 3 (in Fig. 3), and the ACFs of its original series (in Fig. ), it can be interpreted that the original series has a trend, and a high value of ACF of lag 12 indicates the existence of seasonality. 2 Hence, a non-seasonal first-difference to remove the trend and a seasonal first-difference to remove the strong seasonal spikes in the ACFs are tested. Fig. 7 shows the ACFs of the ARIMA (p,1,q)(P,1,Q) 12 model afte r applying the first difference. The nonseasonal plot indicates that there is an exponential decay and one significant ACF of lag 2. Thus, the AR(1) and MA(1) process denoted by ARIMA (1,1,1)(0,1,0)12 is identified. The ACFs of the residuals after applying this ARIMA model shown in Fig. reveals that there is a high value of ACF of lag 12. Therefore, the AR(1) and MA(1) process for the seasonal part or ARIMA (1,1,1)(1,1,1)12 can be identified. The ACFs of the residuals generated from this model are shown in Fig. 9. Since all ACFs are within the two significant limits, the ARIMA (1,1,1)(1,1,1)12 model is adequate. Using the Statgraphic program, the model coefficients can be determined.

Therefore, the ARIMA model should be used to forecast the aggregate demands of Groups 2 and 3. For other product groups, however, the decomposition model should be used because it is more simple yet still adequate. The comparison of the demand forecast errors obtained from the forecasting models and those from the current practice of the marketing department (as presented in Table 3) indicates that the errors of the forecasting models are substantially lower than those of the current practice. Demand Forecasts of Individual Products The demand forecast of product i for period t, dit, is obtained by multiplying the aggregate demand forecast of the product group (obtained from the previous steps) by the corresponding product mix (as presented in Table 4).

Based on the forecast errors obtained from the demand forecasting models, the amount of the safety stock is calculated using the following formula. 12 SSit = sf * ? j * ? ij (3) PRODUCTION PLANNING METHO D The production planning model is developed by initially defining decision variables and parameters, and then mathematically formulating the production planning model. Step 4 of the method requires that the model parameters be estimated and entered into the model. The model is solved for the optimal solution (Step 5). Step 6 recommends that the model parameters are updated, and the model is solved again after one planning period has passed. The production planning problem of the factory under consideration belongs to the class of multistage, multi-item, capacitated production planning model. The models in this class have been discussed extensively in. 6-11 They differ in assumptions, objectives, constraints, and solution methods. Our production planning model is a modification of the multi-stage, multi-product model discussed in Johnson and Montgomery. 6 Its objective is to minimize the total overtime and inventory holding costs. Costs of laying off and rehiring are not considered because laying off and rehiring are not allowed according to the labor union regulation. Since the production cost is time-invariant and all demands must be satisfied, the regular time production cost is thus not included in the objective function. Relevant parameters and decision variables are defined as follows: Parameters : hik = Holding cost per unit of product i at stage k (baht/unit/period) co = Cost per man-hour of overtime labor (baht/man-hour) dit = Demand forecast of product i for period t (units) aik = Processing time for one unit of product i at stage k (hours/unit) (rm)kt = Total available regular time excluding preventive maintenance and festival days at stage k for period t (man-hours) (om)kt = Total available overtime excluding preventive maintenance and festival days at stage k for period t (man-hours) W = Warehouse capacity (units) SSit = Safety stock of product i for period t (units) Iik0 = Initial inventory of product i at stage k (units) N = Total number of products (15 products) T = Total number of periods in the planning horizon (12 periods) K = Total number of stages (5 stages) where SSit = Required safety stock level of product i for period t sf = Safety factor = 1. 64 for a required service level of 95 % of the standard normal distribution ? j = Standard deviation of forecast errors of Group j. ?ij = Product mix of Product i in Group j. Since the errors of the recommended demand forecasting models are lower than those of the current practice, it is clear that SSit based on the use of the models must be lower than that determined from the current practice (assuming that the service levels of both cases are the same). Table 5 presents the required safety stocks of the current practice and the recommended forecasting models at 95 % service level. Table 5.

Constraint (13) must be included since the finished products are very bulky and require significant warehouse space that is quite limited. Work-inprocess inventory does not require significant storage space because it can be stacked. The non-negativity constraint (16) ensures that shortages of work-inprocess inventory do not occur. Input Parameters The initial inventory of product i at stage k, Iik0, is collected from real data of work-in-process or finished good inventories on the factory floor at the beginning of the planning horizon. The inventory holding cost of product i at stage k, hik, is estimated by assuming that the annual inventory holding cost is 25% of the cost per unit of the product at the respective production stage. Since the cost per unit is constant over the planning horizon, the annual inventory holding cost is time-invariant. The factory has enough space in the warehouse to store not more than 40,000 units of finished products. The total available regular time, (rm)kt, is estimated based on the fact that the factory is normally operated 16 hours a day and six days a week, and the total available overtime, (om)kt, is calculated by assuming that the overtime could not be more than six hours a day. The overtime cost, co, is assumed to be constant throughout the planning horizon, and is estimated to be 60 Baht per man-hour. After all related parameters have been estimated and entered into the planning model, the optimal values of all decision variables are calculated using the LINGO software. The computation time takes less than one minute on a Pentium PC. Results of the Production Planning Models with Different Levels of Safety Stock In this section, two production planning models with different safety stock levels (as shown in Table 5) are solved to determine the total cost savings when the recommended forecasting models are applied in place of the current practice. The inventory holding, overtime, and total costs of both models are presented in Table 6. Based on the optimal total cost of the current practice (4,078,746 Baht per year) and the optimal total cost of the recommended forecasting models (3,541,772 Baht per year), the total cost saving is 536,974 Baht per year, or 13. 2 %.

Normally, the optimal decisions in the first planning period will be implemented. After the first period has passed, the new forecasts will be determined, and the model parameters will be updated. The updated model is solved again to determine the optimal decisions in the current period. This is called a rolling horizon concept. However, the details and results of this step are not shown in this paper. DISCUSSION AND CONCLUSION The ARIMA model provides more reliable demand forecasts but it is more complicated to apply than the decomposition model. Therefore the ARIMA model should be used only when the decomposition model is inadequate. When compared against those of the current practice of the company, the errors of our selected models are considerably lower. This situation can lead to substantial reductions in safety stocks. Consequently, the lower safety stocks result in decreased inventory holding and overtime costs. The results of the production planning model are of great value to the company since the model can determine the optimal overtime work, production quantities, and inventory levels that yield the optimal total overtime and holding costs. The production planning method is more suitable than the existing one that does not consider any cost factors. Moreover, it has been proven that an application of appropriate forecasting techniques can reduce total inventory holding and overtime costs significantly. In conclusion, this paper demonstrates that an improvement in demand forecasting and production planning can be achieved by replacing subjective and intuitive judgments by the systematic methods.

Bovine Spongiform Encephalopathy Essay Example For Students

Bovine Spongiform Encephalopathy Essay Bovine spongiform encephalopathy (BSE) is a relatively new disease foundprimarily in cattle. This disease of the bovine breed was first seen in theUnited Kingdom in November 1986 by histopathological examination of affectedbrains (Kimberlin, 1993) . From the first discovery in 1986 to 1990 thisdisease developed into a large-scale epidemic in most of the United Kingdom,with very serious economic consequences (Moore, 1996). BSE primarily occurs in adult cattle of both male and female genders. The most common age at which cows may be affected is between the ages of fourand five (Blowey, 1991). Due to the fact that BSE is a neurological disease, itis characterized by many distinct symptoms: changes in mental state mad-cow,abnormalities of posture, movement, and sensation (Hunter, 1993). The durationof the clinical disease varies with each case, but most commonly lasts forseveral weeks. BSE continues to progress and is usually considered fatal(Blowey, 1991). After extensive research, the pathology of BSE was finally determined. Microscopic lesions in the central nervous system that consist of a bilaterallysymmetrical, non-inflammatory vacuolation of neuronal perikarya and grey-matterneuropil was the scientists overall conclusion (Stadthalle, 1993). Theselesions are consistent with the diseases of the more common scrapie family. Without further investigation, the conclusion was made that BSE was a new memberof the scrapie family (Westgarth, 1994). Transmission of BSE is rather common throughout the cattle industry. After the incubation period of one to two years, experimental transmission wasfound possible by the injection of brain homogenates from clinical cases(Swanson, 1990). This only confirmed that BSE is caused by a scrapie-likeinfectious agent. How does the transmission become so readily available among the entireUnited Kingdom feedlot population? Studies showed that the mode of infectionwas meat and bone meal that had been incorporated into concentrated feedstuffsas a protein-rich supplement (Glausiusz, 1996). It is thought that the outbreakwas started by a scrapie infection of cattle, but the subsequent course of theepidemic was driven by the recycling of infected cattle material within thecattle population (Lyall, 1996). Although the average rate of infection is verylow, the reason why this led to such a large number of BSE cases is that much ofthe United Kingdom dairy cattle population was exposed for many, continuousyears (Kimberlin, 1993). To help control the outbreak, the British government in 1988 introduceda ban on the feeding of ruminant protein to other ruminant animals (Lacey, 1995). Such knowledge for the pathogenesis of the BSE disease shows precisely theactions that must be taken in order to control and minimize the risk ofinfection in healthy cattle around the world (Darnton, 1996). The appearance of BSE has made a sizable impact throughout much of theworld even though few countries, other than the United Kingdom, have experiencedpositive cases (Burton, 1996). The scare of an outbreak in other countries hasled to a great disruption in the trade economy, as well as other factorsconcerning each of the countrys general welfare. However, a rapid increase inthe understanding of the disease over the last four years leaves few unansweredquestions of major importance (Masood, 1996). BSE has been prevented,controlled and eradicated. As mentioned, BSE was first recognized in the United Kingdom and it isonly there that a large-scale epidemic has occurred (Burton, 1996). By the endof 1990 well over 20,000 cases of BSE had been has been confirmed in England,Scotland, and Wales (Filders, 1990). The deadly epidemic started simultaneouslyin several parts of the country and cases have been distributed over a wide areaever since (Cowell, 1996). Besides the United Kingdom, cases of BSE have occurred in the Republicof Ireland. Some of these cases were associated with the importation of liveanimals, meat, and bone meal from the United Kingdom (Cherfas, 1990). Two cases of BSE have also occurred in cattle from the country of Oman. These animals were thought to be part of a consignment of fourteen pregnantheifers imported from England in 1985. Various cases have also been confirmedin Europe, Switzerland, and France (Patel, 1996). The economic consequences of BSE in the United Kingdom have beenconsiderable. At the beginning, the only losses due to BSE were those directlyassociated with the death or slaughter of BSE infected animals (Cowell, 1996). In August 1988, a slaughter policy with part compensation was introduced to helplessen the burden on individual farmers. As the number of BSE cases increased ,and more farmers were experiencing a second case, full compensation wasintroduced in February 1990 (Moore, 1996). In 1989 alone over 8,000 suspectedand confirmed cases of BSE were slaughtered. The compensation costs for theyear were well over 2.8 million pounds and the slaughter costs amounted to 1.6million pounds (Cockburn, 1996). Kristallnacht EssayUnfortunately, the slaughter of the great majority of affected animalsbecomes necessary at an early stage because of unmanageable behavior and injuryfrom repeated falling and uncontrollable behavior (Cowell, 1996). The durationof the clinical disease, from the earliest signs to death or slaughter, canrange from under two weeks to as long as a year. The average period is aboutone to two months (Lyall, 1996). BSE resembles other members of the scrapie family in not having anygross pathological lesions associated with disease. Characteristichistopathological changes are found in the nervous system (Kimberlin, 1993). Incommon with the other diseases in the scrapie family, BSE has a distinctive non-inflammatory pathology with three main features: -The most important diagnostic lesion is the presence of bilaterally symmetrical neuronal vacuolation, in processes and in soma. -Hypertrophy of astrocytes often accompanies vacuolation. -Cerebral amyloidosis is an inconstant histopathological feature of the scrapie family of diseases. At times, only one of the above will occur in an infected animal, while moreoften a combination of the three will occur (Swanson, 1990). Unfortunately, there are no routine laboratory diagnostic tests toidentify infected cattle before the onset of clinical disease. The diagnosis ofBSE therefore depends on the recognition of clinical signs and confirmation byhistological examination of the central nervous system (Westgarth, 1994). Aclinical diagnosis can also be confirmed by simple electron microscopeobservations, biochemical detection of SAF, or the constituent protein PrP(Hunter, 1996). At present, vaccination is not an appropriate way of preventing any ofthe diseases in the scrapie family. There is no known protective immuneresponse to infection for a vaccine to enhance (Blowey, 1991). However, BSE isobviously not a highly contagious disease and it can be prevented by othersimple means because the epidemiology is also relatively simple: -Restrictions on trade in live cattle -Restrictions on trade in meat and bone meal -Sterilization of meat and bone meal -Restricted use of meat and bone meal -Minimizing exposure of the human population -Minimizing the exposure of other species (Moore, 1996)A great deal of concern, much of it avoidable, has been expressed overthe possible public health consequences of BSE. This is understanding giventhat the scrapie family of diseases include some that affect human beings (Patel,1996). As a result of research, the circumstances in which BSE might pose arisk to public health can be defined quite precisely, and simple measures havebee n devised to prevent this risk (Kimberlin, 1993). It is important toemphasize that any primary human exposure would still be across a speciesbarrier and there would be no recycling of food-born infection in the humanpopulation, as happened with kuru and with BSE in cattle (Patel, 1996). Thelogical way to address this risk is to make sure that exposure to BSE is kept toa bare minimum. There are two scenarios for the future course of BSE. The first is thatBSE, like TME and kuru, is a dead-end disease. If this is true and meat andbone meal was the sole source of the infection, then removing this source wouldbe sufficient for the eventual eradification of BSE from the United Kingdom(Hager, 1996). The alternative scenario is that there are natural routes oftransmission of BSE and that the outbreak could turn into an endemic infectionof cattle the way scrapie is in sheep (Burton, 1996). To sustain BSE infectionin the cattle population requires that each breeding cow is replaced by at leastone infected female calf, which then transmits infection to at least one of heroffspring. For BSE to become an endemic, the number of infected cattle wouldneed to increase by horizontal spread as seen in scrapie (Masood, 1996). Theessential prerequisite for controlling such a deadly disease is through goodbreeding and movement records which are currently being compiled in the UnitedKi ngdom following recent legislation (Stadthalle, 1993). Meanwhile theprecautionary measures to safeguard other species, including human beings, arealready in place and refined to meet todays needs. Category: Science
