From the reviews:

„The study of various maintenance policies and models in order to prevent the occurrence of system failure, and reduce maintenance costs is an important area in reliability engineering. … The book may be considered as a state-of-the-art survey of reliability and maintenance theory and models. As such, it is well addressed to postgraduate students, researchers and practitioners in reliability and maintenance engineering, operations research, industrial and mechanical engineering, logistics management and statistics.“ (Vangelis Grigoroudis, Zentralblatt MATH, Vol. 1128 (6), 2008)

„Recently, some very good books on the subject of optimal maintenance policies and models have been available in the literature. This is one of them... Since the most practical method of system reliability or availability assessment is Monte Carlo simulation when other analytical methods become unwieldy or cumbersome to use, the authors have devoted some 20 pages to cover this aspect along with variance reduction techniques, which are inevitable in any simulation approach. There are very few books on reliability that attempt to discuss this in sufficient detail... Another indispensable part of this book is 32 pages list of references included by the authors which provides a reader an indication of how several new developments have taken place in this area over a period of about four decades.

“The reviewer feels, this book will prove to be a good help to a graduate student or a researcher who intends to know the state-of-the-art in the area of optimal maintenance models and policies." (Krisnha B. Misra, International Journal of Performability Engineering, Vol. 4, (3), 2008)
