摘　　要：利用Petri网的动态描述能力,将Petri网应用到通信网动态可靠性分析上。通过分析网络故障的起因,把故障原因抽象为三个子故障系统。根据故障产生、消解的随机性,运用SPN建模,然后运算求解,得到网络可靠度的表达式。最后通过实例验证了方法的正确性。The Petri net is used to analyze the dynamic reliability of the communication network for its dynamic description character in this paper. By analyzing the reasons of network failure, three subsystems of failure are abstracted. Then a stochastic Petri net model is developed and settled, and the expression of the network reliability is figured out. At last, the method is proved to be correct by an example.
