This text presents a systematic discussion of three important questions in software reliability engineering: how to estimate the number of software defects; how to model software operational profiles; and how to estimate software failure rate and quantify software correctness when testing reveals no failures. Researchers will find that this book presents a reasonable summary of related topics and contains a modest amount of original and new research results. Although, due to the space limitation, methods discussed in the main text are selected, a separate section, "Remarks and Problems", is created for each chapter to address ideas and references.

This volume contains contributions from world-leading experts from both the academic and industrial communities. The first part of the volume consists of invited papers by international authors describing possibilistic logic in decision analysis, fuzzy dynamic programming in optimization, linguistic modifiers for word computation, and theoretical treatments and applications of fuzzy reasoning. The second part is composed of 11 contributions from Chinese authors focusing on some of the key issues in the fields: stable adaptive fuzzy control systems; partial evaluations and fuzzy reasoning; fuzzy wavelet neural networks; analysis and applications of genetic algorithms; partial repeatability; rough set reduction for data enriching; limits of agents in process calculus; medium logic and its evolution; and factor spaces canes. These contributions are not only theoretically sound and well-formulated, but are also coupled with applicability implications and/or implementation treatments. The domains of applications realized or implied are: decision analysis; word computation; databases and knowledge discovery; power systems; control systems; and multi-destinational routing.Furthermore, the articles contain materials that are an outgrowth of recently conducted research in the late 1990s, addressing fundamental and important issues of fuzzy logic and soft computing.

Treating fuzzy methodology in hardware reliability and software reliability in a relatively systematic manner, this work is divided as follows: Chapter 1 places reliability engineering in the scope of a broader area, i.e. system failure engineering. Readers will find that although this book is confined to hardware and software reliability, it may be useful for other aspects of system failure engineering, like maintenance and quality control. Chapter 2 contains the elementary knowledge of fuzzy sets and possibility spaces which are required reading for the rest of this book. This chapter is included for the overall completeness of the book, but a few points (e.g. definition of conditional possibility and existence theorem of possibility space) may be new. Chapter 3 discusses how to calculate probist system reliability when the component reliabilities are represented by fuzzy numbers, and how to analyze fault trees when probabilities of basic events are fuzzy. Chapter 4 presents the basic theory of profuse reliability, whereas Chapter 5 analyzes the profuse reliability behavior of a number of engineering systems.

Chapter 4 presents the basic theory of profust reliability, whereas Chapter 5 analyzes the profust reliability behavior of a number of engineering systems. Chapters 6 and 7 are devoted to probist reliability theory from two different perspectives. Chapter 8 discusses how to model software reliability behavior by using fuzzy methodology. Chapter 9 includes a number of mathematical problems which are raised by applications of fuzzy methodology in hardware and software reliability, but may be important for fuzzy set and possibility theories.

Though there have been significant advances in the theory and applications of linear time-invariant systems, developments regarding repetitive control have been sporadic.
