...PRINCIPLES AND APPLICATIONS OF OPERATIONS RESEARCH * Jayant Rajgopal Department of Industrial Engineering, University of Pittsburgh, Pittsburgh, Pennsylvania ABSTRACT This chapter will provide an overview of Operations Research (O.R.) from the perspective of an industrial engineer. The focus of the chapter is on the basic philosophy behind O.R. and the so-called “O.R. approach” to solving design and operational problems that industrial engineers commonly encounter. In its most basic form, O.R. may be viewed as a scientific approach to solving problems; it abstracts the essential elements of the problem into a model, which is then analyzed to yield an optimal solution for implementation. The mathematical details and the specific techniques used to build and analyze these models can be quite sophisticated and are addressed elsewhere in this handbook; the emphasis of this chapter is on the approach. A brief review of the historical origins of O.R. is followed by a detailed description of its methodology. The chapter concludes with some examples of successful real-world applications of O.R. * Maynard's Industrial Engineering Handbook, 5th Edition, pp. 11.27-11.44. 1.1 INTRODUCTION Although it is a distinct discipline in its own right, Operations Research (O.R.) has also become an integral part of the Industrial Engineering (I.E.) profession. This is hardly a matter of surprise when one considers that they both share many of the same objectives, techniques and application areas...

...Journal of Business & Economics Research – July 2005 Volume 3, Number 7 Operations Research And Operations Management: From Selective Optimization To System Optimization Jack A. Fuller, (E-mail: jfuller@wvu.edu), West Virginia University C. Lee Martinec, West Virginia University ABSTRACT The focus of this research paper is to discuss the development of Operations Management (OM) and Operations Research (OR) with respect to their use within the organization’s decision-making structure. In addition, the difference in the tools and techniques of the two fields is addressed. The question is raised as to how distinct the two academic fields have become in light of the application of their models to the service industry. Suggestions are made regarding the possibility of incorporating OM/OR models and their output into the decision making structure of the organization towards the goal of “system optimization”. ORIGINS OF OPERATIONS MANAGEMENT AND OPERATIONS RESEARCH A comparison of the origins of operations management and operations research reveals that both are an innovation of the 20th century. The origin of operations research was in England, circa 1937, and has its roots in scientific management, with its first significant applications to military operations in both World War I and World War II. Operations management had its origins in the early factory system, and was more associated with physical production in a factory environment and it too was strongly influenced...

...the basis of effective operations of any company’s projects, and give accurate insights on the exploration of the minimal resources available to an organization’s disposal. Besides, it enables any company to manage the work force in the process of timely completion of projects and extension of the businesses longevity. Therefore, it is important to define the roles of each party in any project assigned to the organization. Analysis of the case: designing the authorities of a project manager The Beijing EAP Inc. is a company that provided EAPs to many customers. The nature of its operations required the employees to have strong academic backgrounds that qualified them to operate in this multinational service company. Being the largest market holder in the mainland China, the Company had a huge customer base that categorized it as a big corporation. Amongst some customers of BEC were IBM, Siemens, Samsung, Lenovo, Guadong Mobile and the China Development Bank. Consequently, the Company had many projects that prompted the management to subdivide the projects to different segment managers. In this case study, for instance, Mr. Yang represents a training department manager having a communicational breakdown with Ms. Song, a project manager, based on the confusion of the roles each one was to perform. In some cases, the tension escalated to a point where the employees did not know who to approach concerning the progress of projects. Both being project managers at the BEC, the...

The project is called PipeSim, and features static and dynamic pipelines with a very attractive, dynamic and intuitive interface. It is well known that pipeline and pipeline-scheduling are very relevant concepts in computer science studies and it is very important that students can learn these in an easy and reliable way. The simulator makes easy both working in depth about pipeline scheduling and working slowly paying attention in the different stages of the scheduling. However, we designed the simulator knowing that principal users would be students with no experience, so both the execution and the presentation of the results have been carefully developed. In addition to this, to check the success of PipeSim, a survey has been made among some students that used...

...Homework: Specify one area or field which makes use of Operations Research as a tool. Give specific and real examples. According to the website scienceofbetter.org, Operations Research (OR) is basically a discipline of applying advanced analytical methods to help make better decisions. OR can also be called as Management science which also concerns methods for strategic planning and strategic decision support. Therefore, using operations research will be very helpful for executives and companies in order to sustain and even improve their systems or businesses. Some of the fields that use operations research as a tool are education, decision analysis, engineering, marketing, supply chain management, mathematics, project management and a whole lot more. However, the field of supply chain management will be focused in this paper. Supply chain management (SCM) is a sequence of business processes and information that provides a product or service from suppliers through manufacturing and distribution to the ultimate customer (Roger Schroeder, 2007). Basically, this is the management of the flow of goods. Having the right and efficient supply chain management system can increase coordination in a company as well as maintaining the demand for a particular product. On the other hand, this can also be very crucial since a company must be able to think of strategic ways in order to be competitive and keep their customers. However, just like any other function or activity, SCM also...

...more effective when the employees have all the right combination of tools, training, and knowledge to make the products, and provide services to the customers when they are needed. This work grew out of the Tavistock Institute of Human Relations in England. They explored ways to improve productivity and morale in organizations through "action research". The socio-technical approach has focused more on work group interactions than individual performance. Properly structured work groups, it is assumed, can provide incentives, assistance, and social support better than individual job design programs. Autonomous work groups, quality circles are popular examples of this perspective. Groups are often given resources and responsibilities for areas like safety and quality control and work as a team to identify and correct inefficiencies and work issues. Quantitative Management approach involves the use of mathematical modeling to find the best solutions to problems. This can be applied to a variety of workplace challenges, ranging from making decisions during product development to resolving employee conflicts. It is also known as operations research, and involves a more objective, structured approach to problems or solutions. Many industries can be suited to this management philosophy. One important component of the quantitative management approach is an ability to objectively collect information about a problem and possible solutions to develop appropriate, and useful, mathematical models...

...CHAPTER ONE INTRODUCTION OF THE STUDY 1.1 Introduction This chapter introduces the material purchasing factors that impact on food production in hotel industry. The chapter also gives some background information about Ambassadeur Hotel; it outlines the statement of the problem, research objectives, research questions, significance, limitations, assumptions and scope 1.2 Background of the study Material purchase for food products is a function concerned with the search, selection, receipt, storage and final use of a commodity in accordance with the catering industry policy of the establishment. Business strategy literature is replete with evidence that indicate the purchasing methods of a firm have an impact on achieving a firm’s goals. The purchasing function can have an impact on the firm’s ability to achieve its chosen strategies because organizational buying is one of the forces that impact competition (Carr et al. 2000; Landeros and Monczka 1989). As hotels strive to achieve global competitiveness, effective purchasing has assumed great importance. According to Carter and Narasimhan (1996), firms need to recognize the strategic role of purchasing as well as the impacts that it exerts on organizations. The relevance of effectively managing the material resources of an organization to its competitive success has been observed by both practitioners and researchers in purchasing and supply management. As a result, purchasing has evolved in many firms from a low-skill, clerical...
