Dynamic analysis of coherent fault trees

An important characteristic of many engineering systems which cannot be modeled by fault trees to perform system reliability analysis is that they behave dynamically. In this paper, the method of applying Petri Nets (Pns) as a modeling tool to represent the coherent fault trees is discussed. When the repair facility is added into the nets, the dynamic behavior of the repairable system can be studied through the nets by using equivalent Markov chains.
