摘　　要：对于由多个不同故障率部件构成的串联系统,引入系统的机会维修系数概念,根据部件在预防维修间隔期中已经使用的时间判断其是否需要进行机会维修或更换。以系统在有限运行周期内的总维修费用最小化为目标,满足一定可用度为条件,建立多部件系统的机会维修优化模型。运用MATLAB编程进行算例仿真分析,求解出复杂系统各部件的最优机会维修方案。结果显示,运用文中模型能寻求出合适的机会维修系数,有效降低系统的维修成本,并提高其可用度。For series system is consisted of different failure rates components, it introduces system maintenance coejCwient, according to which estimates whether it needs opportunistic maintenance. It establishes maintenance model for the system, which is aimed at the minimum maintenance cost in the limited running cycle, on the condition of certain availability. Using MATLAB to simulate and analyze the example, solves the optimal opportunistic maintenance plan for the system Result shows that the model can find the most suitable opportunistic maintenance coeffwient, effectively reduce the maintenance costs and increase availability.
