BOOK REVIEW
Reliability and Availability Engineering:
Modeling Analysis, and Applications
Kishor Trivedi and Andrea Bobbio Cambridge University Press, 2017
The increasing dependence on the technological infrastructure, especially in advanced economies, is not without its perils. Even short outages
in the infrastructure can have drastic consequences, ranging from economic losses in the least, all the way to loss of human life in the worst
case. It is thus imperative that our complex and critical infrastructure, including the likes of the Internet, transportation, energy supply,
communications, health, financial services and commerce be designed and implemented with assurance of a certain level of dependability. While the
aforementioned scenarios are typical, how can their dependability be guaranteed a priori with a certain level of confidence? This makes it
imperative that suitable techniques that enable us to assess, predict, verify and validate the level of reliability, availability, safety and
maintainability of these products, services and infrastructures be developed. Now there are many books that provide some insights into the methods
of dependability assurance but none of them provide a very comprehensive set of techniques in the context real-life applications. The plethora of
analytical techniques available for the evaluation of reliability and availability leaves a practitioner often in a quandary, unable to figure out
the most suitable approach to analytically evaluate the system under investigation
The primary aim of this book is to comprehensively consider in details all techniques together showing similarities and differences and
pointing out the pros and cons of each approach. Furthermore the book not only covers classical techniques like reliability block diagrams,
faulttrees, network reliability and Markov models but also more advanced techniques like non exponential models and new approaches and analysis
techniques, like the use of Binary Decision Diagrams, Dynamic Fault Trees, Bayesian Belief Networks and stochastic Petri nets. Furthermore, the
book particularly addresses the multi-level modeling for the analysis of large systems combining different modeling formalisms. Another unique
feature of the book is that there are three chapters exclusively devoted to dealing with non-exponential distributions.
A major strength of the book is a large number of solved examples, a significant number of real case studies and many problems that can be
assigned as homework. Some of the examples are strung through different chapters so as to show the application of different techniques on the
same basic example. We are planning a solution manual and a set of power point slides for instructors using this book as a text. The software
packages SHARPE and SPNP can be obtained by contacting the first author. Three key topics that are not covered, except in a few examples, due
to size limitations are: statistical techniques, discrete-event simulation and optimization
Over forty years of experience of both of the two authors in developing techniques, software applications and real-life experience and in
consultancy and teaching, is distilled in this book. The book can be used for a two semester course on reliability engineering; it can be used
by practicing engineers as it is comprehensive and contains many real-life case studies; and it can be used a reference by researchers in
reliability engineering.
The book is divided in 6 Parts and 18 Chapters along the following contents table.
