摘　　要：为了在复杂可修复系统的可靠性模型中引入修复过程,实现系统使用维修保障全过程仿真,使用Petri网建立了一种可修复系统的可靠性模型,通过模型内部token的移动控制系统组成单元的状态。以某型飞机为例进行了仿真。仿真结果表明,模型易于实现,具有较好的拓展性,可以有效地反映系统的修复过程,从而为系统的使用维修保障全过程仿真提供条件。In order to realize the simulation for the whole process of operation, maintenance and support, we built a reliability model of complex repairable system by using Petri Nets. In this model, the status of each composed unit is controlled by the tokens＇ movement. A certain type of aircraft was taken as an example for simulation. The result showed that the model can be implemented easily and can reflect the repair process ef- fectively. The model is useful for simulating the whole process of operation, maintenance and support.
