| 摘 要： | 提出了一种基于随机Ｐｅｔｒｉ网的可修控制系统的稳态可用度的计算方法。该方法利用随机Ｐｅｔｒｉ网作工具来分析系统的状态变化关系，从而得出相应的Ｍａｒｋｏｖ链状态转移图，再利用由此得来的状态概率矩阵方程求解，计算较为简单。

| Abstract: | Based on Stochastic Petri Nets(SPN), a calculation method of steady availability of repairable control systems is proposed. The method is comparatively simple, because it uses SPN as a tool to analyze system states. The corresponding Markov chain, through which the matrix equation on probability of system states is obtained, is found out according to the SPN model. |
