| 摘 要： | 利用Petri网与马尔可夫链的同构关系,采用Petri网与马尔可夫链理论相结合的维修保障系统性能分析方法,对系统性能有效评估提供了理论依据。通过两个不同实例分析了系统状态空间、各状态在稳态下的期望概率、系统可靠性和维修人员的工作强度。实例表明,相比传统的建模方法,在分析装备维修保障各状态间的逻辑关系和系统动态过程中,随机Petri网具有显著的有效性和优越性。

| Abstract: | The modeling of the system is discussed on Stochastic Petri net(SPN) with the transition subjected to Markov process.The determination of state space,expectation probability and duration of each state,the reliability of the system and the working intensity of maintainers are analyzed through examples.Compared with traditional modeling methods,in the course of analyzing the state space and logic relation among the states and the dynamic process of the system,SPN is discovered to be more effective than and superior to the traditional methods. |
