Operational Research Models and Methods in CIM1
Abstract : Many models and methods of Operational Research can be adapted for industrial applications. In this chapter, we show on one hand the main problems of a manufacturing system and, on the other hand, how they can be ranged in a hierarchical order, derived from a CIM architecture (from the strategic decisions to the production constraints). Then, we present an Operational Research tool for solving each of these problems.

1 Introduction
Flexible Manufacturing Systems (FMS) are nowadays installed in the mechanical industry, especially in car factories. However, the market constraints impose to always improve the production system and the whole production organization. The concepts developed by Taylor and applied at the beginning by Ford are progressively abandoned and replaced by the Just-In-Time concept and the Computer Integrated Manufacturing philosophy (CIM). One of the aims of the CIM philosophy is to provide an integrated information system which avoids the rigid separations between the different functionalities of a complete production system. With such integrated information systems, the loss of time on one hand between the customer order and the part delivery, on the other hand between the product design and its manufacture will be drastically reduced. To understand the complete production system, it is relatively easy to find in the scientific literature excellent general books explaining the different aspects of the Production and Operations Management (POM) ([1], [2], [3], [4], [5]). It is more difficult to discover a writing dedicated to use of Operational Research (OR) models and methods in the industrial context [6]. And it is quite impossible to find a book which offers a good balance between POM and OR … In this chapter, we will show how a CIM architecture can be partially decomposed along two…...

...taking the financial sector in to consideration. The research covers all sectors in the Chinese stock market. Main outcomes are listed below. Leverage imposes negative effects on investment, especially on non-state owned firms. Like Financials, Manufacturing and other highly regulated sectors, the inverse impacts of debt are week as well. However, marginal q fails in proof under the specific environment of the Chinese capital market which is still immature. High-leveraged firms experienced reverse influences of marginal q on investment. To sum up, over-debt financing indeed blocks the sustained investment. Relatively speaking, state owned firms in China suffer less since they are supported by the government and have fewer restrictions. Key words: financial leverage, marginal q, gross investment and state owned firms 2 ACKNOWLEDGMENTS Firstly, I would like to express my strong gratitude to my supervisor, Prof. Börje Johansson, whose profound knowledge, guidance and patience, greatly enhanced my graduate experience.

...Business research Business research can be described as a systematic and organized effort to investigate a specific problem encountered in the work setting that needs a solution. It comprises a series of steps designed and executed, with a goal of finding answers to the issues that are of concern to the manager in the work environment. This means that the first step in research is to know where the problem areas exist in the organization, and to identify as clearly and specifically as possible the problems that need to be studied and resolved. Once the problem that needs attention is clearly defined, then steps can be taken to gather information, analyze the data, and determine the factors that are associated with the problem and solve it by taking the necessary corrective measures. This entire process by which we attempt to solve problems is called research. Thus research involves a series of well-thought-out and carefully executed activities that will enable the manager to know how organizational problems can be solved, or at least considerably minimized. Research thus encompass the process of inquiry, investigation, examination, and experimentation. These processes have to be carried out systematically, diligently, critically, objectively, and logically. The expected end results would be the discovery that will help the manager to deal with the problem situation. Definition of research 1. A voyage of discovery or a journey/movement from the known to unknown; An......

...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......

...COMPUTATIONAL COMPLEXITY OPERATIONS RESEARCH Pooja Punjabi Manash Hazarika INDIAN INSTITUTE OF MANAGEMENT, KOZHIKODE COMPUTATIONAL COMPLEXITY Computational Complexity is a measure of the computational time taken by a particular algorithm. In a scenario where there are multiple algorithms available for a particular problem, the effectiveness of any particular algorithm is gauged on the basis of the time constraint. This is done by breaking the algorithm into its basic steps and then taking a count of each of them. Hence greater is the number of steps, greater is the complexity. Now for example, if we take two 5 bit binary numbers and XOR them, the number of steps taken is 5 and if the same process is repeated for a 100 bit binary number, the number of steps goes up to 100. The algorithm employed in either case is the same; the complexity is given by the size of the numbers. When we say size of a number n, it is defined as the number of binary bits which are required to denote ‘n’ in base 2. For example, 5 in base 10 when expressed in binary takes the form 101, thereby giving n = 3. Similarly 20 is given by 101002 which makes n = 5. Now if we XOR any two numbers each of size n=b, the number of steps taken will be ‘b’. Hence we can say that XORing those numbers has computational complexity of order ‘b’ which is denoted by O(b). This can be applied to even simpler applications like addition wherein if we are to add two n digit numbers, the minimum number of steps taken......

...the probability of their return to the same hotel (Choi & Chu, 2001). Hotels are increasing their investments to improve service quality and the perceived value for guests so as to achieve better customer satisfaction and loyalty, thus resulting in better relationships with each customer (Jones et al., 2007). Relationship quality has a remarkable positive effect on hotel guests’ behavior, it creates positive word of mouth (WOM) and increments repeated guest rates (Kim et al., 2001). In the other hands, to obtain loyalty and to outweigh other competitors, hotel providers must be able to obtain high levels of customer satisfaction for the service supplied. There are several studies that analyze the needs and the desires of tourists. A research by Wuest et al. (1996) defined the perception of hotel attributes as the degree to which guests may find various services and facilities critical for their stay in a hotel. Hotel's attributes such as cleanliness, price, location, security, personal service, physical attractiveness, opportunities for relaxation, standard of services, appealing image, and reputation are recognized as decisive by travelers to assess the quality of the hotel (Atkinsons, 1988; Ananth et al., 1992; Barsky & Labagh, 1992; Cadotte & Turgeon, 1988; Knutson, 1988; McCleary et al., 1993; Rivers et al., 1991; Wilensky & Buttle, 1988).

...attempt to discuss the background of the study, which provides a general idea on the scope of the study. In addition, this chapter presents the identified research problem and it followed by the objective of the study. Then this chapter will proceeds with the explanation of the importance of the study. The main focus of this study is about student’s satisfactions towards facilities and services provided by College Poly-Tech Mara Kuala Lumpur (KPTM). Based on Lawrence, O. Picus, et al., Services it can be concluded that there is essentially no relationship between the quality of school facilities and student performance when other factors known to impact student performance are accounted for. This does not suggest investments in school facilities are not important-all children are entitled to attend school in safe, clean, and appropriate educational environments. However, policymakers should be aware that investments in facilities by themselves are unlikely to improve student learning. The main reasons of the writer choose did topic because to identify the factors that influence students satisfactions toward facilities and services provided College Poly-tech Mara Kuala Lumpur services. Besides, the organization can use all the information to perform well to their students with the effective strategies. This topic or this research can help KPTM to serve the good service and facilities to their students. 2.0 Statement of the Problem 2.0.1 The building in KPTM a small. ......

...Research Method Internal Auditing versus external Auditing When it comes to the subject of the audit, one will often find the concepts of internal audit and external audit. If these two audits are necessary for the good functioning of company, and if the collected sources agree that the skills required for these two notions are relatively identical, it remains not only tasks and the environment of the internal auditor and the external auditor differ.   In order to best support our report, we gave a point of honour to diversify sources and points of view. Our researches were principally based on key words such as: internal auditing, external auditing, differences between auditors, cooperation between auditors, similarities between external and internal auditing. The diversification of our sources has in fact been paramount and allowed us to have a global vision of the subject and the issues it implies. So we will be based on data of the IFACI and the CNCC, the point of view of a University Professor, that of an NLC internal auditor, reflections and axes of various analysis collected from the blog Be audit you can Be (http://amais5.tumblr.com/).   In the light of the evidence and their convergence on some specific aspects concerning the general question “How internal and external auditors can benefits for each other ?”, the following questions are imposed on us as problematic to treat during this report: What precisely are the differences between these two audit......

...thinking-reasoning ability for one to understand and even to apply its knowledge in real business situation. Scholars were able to develop theories and models after studying real life situation at the work place (industries). An individual may go through the business management course but in the end cannot or will not be able to apply the knowledge acquired in the course at the workplace or managing oneself (self-management). In the traditional classroom teaching, there is hardly any scope for the student to interact with the teacher, teaching learning resources and the teaching learning environment. Teaching becomes very monotonous and students have to mostly rely on rote learning. Most often, classroom teaching is dominated by the lecture method. Learning has shifted from response strengthening to knowledge acquisition and from knowledge acquisition to construction of knowledge. In this context, the duty of the teacher is to provide appropriate environment where the student will construct his or her knowledge by interacting with his physical and social environment. It is in this context that there is a need to orient teachers and develop appropriate context specific teaching learning resources useful to enhance the quality of teaching-learning process. It was also observed that Business Management teachers do not make the lesson interesting and practical due to the absence of teaching learning resources in their lesson delivery. Obviously, teaching learning resources aid......

Keywords: Nurse, experience, HIV, infection, injury, exposure. Abstract: Curationis 31 (4): 13-23 The purpose of the research was to describe the experience of nurses in the studied hospital who had been exposed to possible HIV infection during injury or exposure on duty. A qualitative phenomenological descriptive study was used to describe the emotions and non-verbal reactions of the twelve participants during two subsequent in-depth interviews. These were conducted post-exposure, and after counselling and prophylactic treatment took place. The nursing staffs from a selected private hospital Were included in the study after exposure of blood and/or human body fluid. After completion of the study, it was found that the exposed staff's experience had two main categories. Firstly, they were grieving for the loss of the concept of being healthy and invincible, blessed with nursing sldlls and definite goals in life. The bereavement process included phases of denial, anger, anxiety and fear, with recurring thoughts regarding the adverse events, as well as acceptance which developed with time. The bereavement process and shock of the exposure had wider consequences to the family, as......
