The objective of my research work is to analyze the behavior and performance of repairable industrial systems by utilizing available information and uncertain data. Fuzzy set theory has been used in the technique for handling the uncertainties in the data and then behavior of the system are analyzed in the form of fuzzy membership functions of various reliability parameters namely systems failure rate, repair time, mean time between failures MTBF , expected number of failures ENOF , reliability and availability which affects the system performance. Major advantages of proposed technique is that it gives compressed range of prediction for all computed reliability parameters by utilizing uncertain data. Further using these results, system performance has been analyzed by formulating a nonlinear fuzzy optimization problem by considering reliability and cost as objectives. Also the technique has been applied for a time varying failure and repair rate model instead of constant failure rate model. The present thesis is organized into nine chapters which are briefly summarized as follows:.

Thesis abstract is an essential part of the dissertation paper. It is a summary of a complete work. It gives readers a chance to discover the key points of your dissertation, its research chapter, methodology and results part. Writing a proper abstract is important. Students use various techniques and guidelines to perform a perfect thesis abstract. Proper structure of thesis dissertation is crucial.
PhD dissertation projects require an abstract by default. This brief section summarises the key ideas and findings of your study. Frequently, it is also the only part of it read by other academic practitioners. The key problem with PhD abstracts is the need to condense hundreds of pages in one or two paragraphs of text.
All theses and dissertations must have an abstract at the beginning of the document that is formatted according to SHSU guidelines. The abstract is a descriptive summary, no longer than words, composed of three principal parts:. This main abstract ties together the entire document, summarizing all of the research and preparing readers on what to expect in your manuscript. Unavoidably, this will duplicate some of the introductory material in each article. It has been preformatted to meet the SHSU requirements outlined on this page.
