RELIABILITY AND COST ANALYSIS OF SOME INDUSTRIAL SYSTEMS WITH VARIED DEMAND FOR THE PRODUCTS

Abstract

The present thesis entitled quotReliability and Cost Analysis of Some Industrial newlineSystems with Varied Demand for the Productsquot is an attempt to develop the newlinereliability models considering different situations depending on the variation in newlinedemand and production capacity of systems on the basis of information gathered newlineon failure times, repair times, other rates, costs from General Cable Energy India newlinePrivate Limited, with the following objectives: newlineand#61623; To understand the process of industries and to create a model(s) for the newlineselected industrial system. newlineand#61623; To obtain the reliability, the expressions for the mean time to system newlinefailure and for various other measures of the systems effectiveness. newlineand#61623; To analyze various other measures like cost-benefit analysis, busy period, newlinemean time to system failure and expected number of visits by repairmen newlineusing semi-Markov process and regenerative point technique. newlineand#61623; To know the profit function graphically with respect to various rates, costs, newlinerevenue, probabilities. newlineand#61623; To make comparison between the models taken two at a time for the newlinesystem to be studied under different situations/ considerations and to newlineidentify which and when one model is better than the other. newlineData/information on failure times, repair times, various costs and newlineprobabilities has been gathered visiting General Cable Energy System/Plant. Then newlinereliability models have been developed on the basis of the situations existing in newlinethe plant visited. Reliability, Mean Time to System Failure (MTSF) and various newlineother measures of the system effectiveness have been obtained by making use of newlinesemi-Markov processes and regenerative point technique. Expression for the newlineprofit has been obtained for each of the models discussed using the obtained newlinemeasures of the system effectiveness. Computer programs using BASIC / C newlinelanguage were developed for evaluating various measures of the system newlinexxix newlineeffectiveness and hence the profit for particular cases, that is, for some numerical newlinevalues of various rates, costs, revenue, probabilities taken on the basis o
