內容簡介：
In the area of system reliability analysis, dynamic and dependent behavior such as multi-state, multi-phase, functional dependence, cascading failures, and sequence dependence has been recognized as a significant contribution to problems in overall system reliability. However, with the incorporation of the dynamic and dependent behavior, resulting dynamic system reliability models cannot be efficiently and accurately solved by existing state space based methods such as Markov methods. In this presentation, an overview on various dynamic and dependent behavior will be presented first. Efficient combinatorial approaches, in particular, decision diagrams and transform methods will then be discussed for the reliability analysis of complex dynamic systems. The application and performance of those combinatorial methods will be demonstrated through analyses of examples in areas of computer systems, phased-mission systems, capacity networks, and sensor networks.
