METHODOLOGY DEVELOPMENT DEVELOPMENT OF TRANSPORTATION METHODOLOGY IN OPERATION RESEARCH “PENGEMBANGAN METODE TRANSPORTASI DALAM OPERASI PENELITIAN” TYPE II – COMPARE & CONTRAST IQBAL TAWAKKAL - 1506694736 PROGRAM MAGISTER TEKNIK INDUSTRI - SALEMBA UNIVERSITAS INDONESIA 1. INTRODUCTION A special class of linear programming problem is Transportation Problem, where the objective is to minimize the cost of distributing a product from a number of sources (e.g. factories) to a number of destinations (e.g. warehouses) while satisfying both the supply limits and the demand requirement. Because of the special structure of the Transportation Problem the Simplex Method of solving is unsuitable for the Transportation Problem. The model assumes that the distributing cost on a given rout is directly proportional to the number of units distributed on that route. Generally, the transportation model can be extended to areas other than the direct transportation of a commodity, including among others, inventory control, employment scheduling, and personnel assignment. Transportation was one of the earliest application areas of operations research, and important transportation problems, such as the traveling salesman problem, vehicle routing problem, and traffic assignment problem, contributed to fundamental knowledge in operations research. Transportation remains one of the most important and vibrant areas of operations research...

...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...

...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...

...Applied Modeling with Military Operations (non-war) Modeling or model is a simplified representation of a situation or problem and modeling is the process of building, refining, and analyzing that representation for greater insight and improved decision making. Modeling is also a mathematical or logical depiction of a system’s behavior. Simulation, is otherwise the device that implements the model. In many military operations, simulation is distinguished among three classes (rough). Live simulations, this involves real people using real equipment in the physical world (real world), like large field exercises. Virtual simulation, involves real people using simulators, flight simulators and/or actual information systems, this often provides realistic acts. Lastly, constructive simulations, this involves simulated people and systems operating in the simulated world, as in things like simulated combat, here users set the initial conditions and run the simulation to see what happens. Simulations are developed from the thoughts of human designers. All simulations are tested to assure accuracy and effectiveness, to illuminate specific issues or problems. The process that covers these mistakes and issues is associated with verification, validation and accreditation. These three sources are applied to a simulation development cycle that operated by the real world system, and is replicated and identified and the conceptual model of it is then identified. This conceptual model is...

...Operations Research and its Prospects in Pakistan Prof. Dr. Shoaib ud Din Mathematics Department Punjab University, Lahore, Pakistan Operations Research has had an increasingly great impact on the management of organizations in the recent years. In fact, with the exception of advent of electronic computer, the extent of this impact seems to be unrivalled by that of any other recent development. However, all the development in this field has gone almost unnoticed in most developing countries including Pakistan. This article is an effort to introduce Mathematics community in the country to the subject and its achievements. A brief history In order to appreciate the importance of OR in the world today it is important that we know something of its history and evolution. Although roots of Operations Research can be traced back many decades, it is generally agreed that this discipline began during World War II. During the War team of British scientists with diverse background were called upon to study the strategic and tactical problems associated with air and land defense of the country. The establishment of this scientific team marked the first formal Operations Research activity. Their efforts were allegedly instrumental in winning the Air Battle of Britain, The Island Campaign in the Pacific, the Battle of the North Atlantic, and so on. The name Operations Research-Operational Research in the United Kingdom – was apparently coined because the problems assigned to this team...

Gómez-Pulido (University of Extremadura, Spain jangomez@unex.es) Juan M. Sánchez-Pérez (University of Extremadura, Spain sanperez@unex.es) Abstract: This paper presents a project that provides both, to professors and to students, a tool that is useful for studying, teaching and learning how pipelines work and how they can be scheduled in an easy and widespread way. 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...

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...

...Affiliation) Date Introduction The organization of corporate structures is important in the allocation of duties and roles, supervision of employees at the workplace as well as the efficient coordination of workflow in an organization. These plans form 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.
