This book brings together all those areas of reliability engineering and management which are specifically relevant in equipment procurement and use. Reliability engineering is too frequently viewed as an activity mainly relevant to design, analysis and production. Application of its concepts by the equipment user is however equally important, since these concepts should guide product selection, specification and procurement and be the basis for performance monitoring and optimized replacement policies. Furthermore, field failure reporting and analysis is the only way of creating a meaningful reliability and maintainability data bank for use in future product procurement, system design and the determination of optimum replacement schedules. Chapters one to seven constitute an introductory section of the book, intended to familiarize readers with no reliability background with the terminology, concepts, relationships and methods of calculation of the subject to the level required to understand and appreciate the main body of the book, i.e. chapters 8 to 21. Chapter 3 provides a summary of the probability and statistical concepts and methods necessary for this purpose.
Chapters 8-10 cover product procurement based on life cycle cost, i.e. the total cost of ownership rather than merely the cost of acquisition. Chapter 11 deals with the allocation of subsystem dependability targets so that system requirements will be met. Chapter 12 covers procurement dependability specifications. Chapter 13 deals with comparative product evaluation prior to purchase. Chapters 14-16 cover failure reporting and analysis, with special attention, in chapter 16, to the analysis of equipment ageing. Chapter 17 deals with equipment inspection frequency and chapters 18-21 are devoted to the optimization of replacement and overhaul strategies and schedules. The book is based on a postgraduate course given at the Technion Israel Institute of Technology and is suitable for engineering final-year undergraduate and post-graduate courses. It is however particularly intended to be of value to all engineers and managers in industry, public utilities and the services who are responsible for the selection, procurement and operation of equipment and systems. It is meant to be understood by non-specialists and non-methematicians.
Extensive references are provided for those who wish to pursue the various topics at greater depth or to see the derivation of equations which in the book are only quoted. A selected bibliography to guide further reading is also provided.
