| 摘 要： | Petri网自1962年提出以来，倍受工业界和学术界的广泛关注。经过几十年的时间，Petri网的理论不断的完善，Petri网在各行业中不断的被应用。本文主要讨论了Petri网在系统可用性分析中的应用。首先从Petri网的基本概念和基本模型出发，讲述了随机Petir网模型（SPN）、广义随机Petri网模型（GSPN）和随机回报网模型（SRN）。然后以冗余备份系统为例，讨论了随机Petri网在系统可用性分析中的应用以及随机Petri网模型的分析。最后讨论与其它建模方法相比，利用随机Petri网来建立系统可用性模型的优点。

| Abstract: | Since presented in 1962, Petri Net is generally focused by academy and industry. In this paper, the application of stochastic Petri net on system availability analysis is mainly discussed. With the beginning of the basic concepts and models of Petri net, stochastic Petri net (SPN), general stochastic Petri net (GSPN) and stochastic reward model (SRN) are illustrated. The application of stochastic Petri net on system availability analysis and analysis of stochastic Petri net model is discussed with the example of standby systems. In the end, the advantages of using stochasticPetri net to model a practical system are discussed comparing to other modeling methods. |
