| 摘 要： | 研究了系统逻辑关系的Ｐｅｔｒｉ网表示，基于Ｐｅｔｒｉ网的建模方法，采用Ｐｅｔｒｉ网模型求系统最小割集的自顶向下法，与故障树方法相比，这种方法可同时获得系统的最小割集和最小路集，且求解的效率高，实例分析证实了这一点。

| Abstract: | The Petri net is employed to model the logical relation and to get the minimal cut sets and the minimal path sets of the system's event, a top-to-down algorithm for this purpose is gotten. Compared with the fault tree analysis method, The Petri net method can get the minimal cut sets and path sets at the same time and is more effective. An example is employed to verify this point. |
