This book is actually based on compilation of theoretical research published by the authors on the subject of importance factors. The importance of importance factors in the reliability and safety of systems can hardly be 978-1-119-99344-5emphasized. This book is a compendium on the subject. However it is observed that there are not many real case studies presented in the book which otherwise would have added the value of the book. For example, the nuclear system safety, where the application of importance measures is an utmost necessity in carrying out level-1, level-2 and level-3 safety analyses of nuclear plants could have been discussed at some adequate length to provide insight into actual applications rather than winding up discussion in just 11 pages excluding three pages of references in the last chapter (chapter 19) of the book. However, the reviewer feels that it is a good compilation and discussion of various importance measures and provides theoretical background and discusses relative advantages of various importance measures that are in vogue for reliability and safety studies, particularly in the category of structural, reliability and lifetime importance measures.

The authors do indicate the utility of various importance measures in the reliability design of systems particularly in redundancy allocation and in improving reliability of various system configurations, flow

network systems including the problem of component assignment in a system, sensitivity analysis and in

optimization problems.

The reviewer finds this book quite useful and recommends to the students and researchers of reliability and risk to have a closer look at it so that further developments can be initiated to develop practical tools

for a realist approach to risk-based reliability design of systems. This book should be a good addition to a

library of books on reliability and risk.
