针对多部件系统固定维修时间长的特点,提出采用机会维修策略,将预防性维修和故障维修有机结合起来,从而分摊系统的固定维修时间,实现提高系统可用度的目的.为此,分析了系统的故障率特性,以及最小维修下的随机故障时间的产生特点.在此基础上,以各部件机会维修役龄为变量,最大化可用度为目标,给出了系统可用度仿真优化方法.最后通过算例,验证了该仿真算法的正确性.

A multi-component system has the long fixed maintenance time, so the opportunistic maintenance policy is adopted to put preventive replacement and corrective replacement together, so that the long fixed maintenance time can be shared by more than one component, and the system availability can be improved. Then, the generation characteristics of the random failure time are researched based on the replacement maintenance and the minimal maintenance. Furthermore, by choosing the opportunistic replacement ages of each component as optimized variables, a simulation algorithm based on an opportunistic maintenance policy is designed to maximize the total availability. Finally, the simulation result shows the validity of the algorithm by an example.
