Operations management has an impact on the five broad categories of stakeholders in any organisation. Stakeholders is a broad term but is generally used to mean anybody who could have an interest in, or is affected by, the operation. The five groups are: * Customers - These are the most obvious people who will be affected by any business. What the chapter goes on to call the five operations performance objectives apply primarily to this group of people. * Suppliers - Operations can have a major impact on suppliers, both on how they prosper themselves, and on how effective they are at supplying the operation. * Shareholders - Clearly, the better an operation is at producing goods and services, the more likely the whole business is to prosper and shareholders will be one of the major beneficiaries of this. * Employees - Similarly, employees will be generally better off if the company is prosperous; if only because they are more likely to be employed in the future. However operations responsibilities to employees go far beyond this. It includes the general working conditions which are determined by the way the operation has been designed. * Society - Although often having no direct economic connection with the company, individuals and groups in society at large can be impacted by the way its operations managers behave.

Operations Research

...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...

...1. Why is it undesirable for the United States to evolve into a service economy? It is undesirable for the United States to evolve into a service economy because several problems arise if jobs shift from manufacturing to service. One is that service job pay less. Many service jobs are in minimum wage, while hourly wages from manufacturing jobs have historically exceeded the minimum wage by a substantial margin. As a result the standard living will necessarily decline. Furthermore, manufacturing allows the firm to capture payoff for the development of new technology. If this payoff is lost, so is the incentive to invest in research. The decline of manufacturing domestically has led to a shift in jobs from the manufacturing sector to the service sector. Because there are major disparities in labor costs in different parts of the world, there are strong incentives for American firms to locate volume manufacturing facilities overseas to reduce labor costs. 2.What disadvantages do you see if the CEO is primarily concerned with the short-term ROI? In the short term, decreasing the denominator by cutting back on the investment in new technologies or new facilities. Performance is measured over short time horizons. There is little motivation for a CEO to invest in a project that is not likely to bear fruit. 3.Can you think of companies that have gone out of business because they focused only on cost and were not able to achieve a minimum quality standard? -“Enron went from...

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...

For example studies by Lockwood [1989], stone [1988] and WORSFOLD [1989] found hotel managers to be more autocratic, assertive, competitive, stubborn, spontaneous, cynical, critical, controlling and practical.
