【摘要】 Ｐｅｔｒｉ网以图形化的方式直观地描述了离散事件系统的各种关系和行为，且以网络理论和代数理论等作为数学基础，可方便地分析离散事件系统的各种特性．更由于其形式化的描述方法，能够直接由模型转化为代码实现对系统的控制．因此在计算机系统的建模、分析和控制综合中得到广泛应用．本文介绍了 Ｐｅｔｒｉ网的基本概念、特点、分析方法及其应用．更多还原

【Abstract】 As a graph tool, Petri nets can be used to describe most of relations and behaviors, visually in the discrete event dynamic system. As a mathematical tool, the analysis of behavior properties and performance evaluation can be done conveniently, using net theory and algebraic theory. And as a formal model method, Petri nets models can be directly convert into codes to realize system control. Due to these advantages, Petri nets are used widely in the modeling, analysis and control of computer system. This paper described basic concept, feature, analysis method and application of Petri net.更多还原
