摘　　要：将一种基于Petri网的故障树分析法运用于飞机配电系统的可靠性分析,以库所和变迁为节点,有向弧的指示方向表达系统故障的传播关系。同时提出一种应用Petri网的关联矩阵求最小割集的新算法,此算法按照指定关联矩阵中所表达的输入、输出关系直接从关联矩阵得出割集,易于计算机程序的实现,而且对于求有重复事件Petri网模型的割集更为简单、直观,避免了传统飞机配电系统可靠性分析方法中分析复杂,减少了计算量,弥补了传统故障树分析法中的不足。The Petri network based failure tree analysis method was applied to the reliability analysis of airplane power distribution system, which took place and transition as nodes and expressed the transmission relation using the directed arc. Meanwhile, a new algorithm to solve the minimum cut set was introduced, which used the associated matrix of the Petri network. The proposed algorithm got the cut set directly from the input-output relationship of the designed associated matrix, thus it was easy for computer procedure, and more easy and intuitional to solve the cut set of Petri network model which had repeated events, thus the short-comings of traditional reliability assessment methods are overcomed.
