摘　　要：采用事件调度法的策略对装备使用与维修过程进行仿真,给出了修复后性能下降的可修件在先换新件和先换旧件两种策略下备件可用概率的仿真算法。该算法能精确计算安装在不同装备上、具有不同故障间隔时间分布、不同修复时间分布、可修次数受限的可修复部件的备件可用概率。仿真算例验证了算法的正确性。The simulation algorithm of probability of spares sufficiency for repairable item with degenerate performance is offered through simulating the process of use and maintain of components. Event scheduling method is the main tactic of the simulation program. The algorithm can resolve the problem of calculating the probability of spares sufficiency for those repairable items whose used time and distribution of time between failure and distribution of time to repair are different.
