摘要：
A property observed in high reliability fault-tolerant control systems is the relatively rare occurrence of component failures compared to the frequent occurrence of redundancy management decision events. This property leads to a temporal decomposition of the semi-Markov chain reliability model into two time-scales: a slow time-scale for failure events and a fast time-scale for FDI events. Conditions are described under which a semi-Markov chain reliability model of a high reliability fault-tolerant control system can be approximated by an enlarged Markov process, the parameters of which are derived from the parameters of the semi-Markov chain. © 1990.
