Additional text
From the reviews:
"The book describes various models of shock and damage in reliability theory, and derives the optimal policies for such models. … covers a large number of shock and damage models, and opens new areas of research. It can be found to be useful to graduate students and researchers in reliability theory." (Moshe Shaked, Zentralblatt MATH, Vol. 1144, 2008)
