Reliability Modeling and Analysis of Some Process Industrial Systems

Abstract

The study of operational research started during the second world war and afterwards. With the development of operational research, the study of reliability theory emerged as by product in context of defence studies. The words reliable and reliability are in use from ancient time. In fact these occur frequently in social, political, economical and practical fields to indicate the efficiency of a person or a mechanical equipment. A mathematical shape to the word reliability was given later in 1950 with its scientific use for defense purpose. Realizing its importance, the study of reliability theory was developed in western world. The development of reliability technology in India is an interesting and encouraging history for researchers. The theory of reliability plays an important role, directly or indirectly in almost all of our daily life problems. Some of the systems whose reliability is of immediate concern to the society in general are power, transportation, medical care, steel and communication industries etc. The history of modern engineering reflects that system failures can occur in any field. Industrial accident in Union Carbide, Bhopal in 1984 and power reactor accident in Chernobyl, USSR in 1986 are prime examples of complex system failure. The reliability analysis of an industry can help the management in taking timely decision for its smooth functioning. This can also help the management to understand the effects of increasing/decreasing repair rate of a particular component or sub system. In order, to obtain maximum output it is necessary to run each of the unit in good condition, i.e. each part of the equipment of the unit should run failure free. Therefore, in the present analysis we have focused on the work about reliability, modeling and analysis of some process industrial systems. The present thesis consists of six chapters. Chapter I presents the historical background and development in the field of reliability technology.
