摘　　要：针对多部件串联系统,提出了一种定期预防性维修策略。首先,介绍了多部件串联系统的一般模型和3种维修策略;其次,分析了定期预防维修的成本,并构建了优化模型;然后,利用遗传算法实现了成本最小化;最后,通过案例,将3种维修策略的成本进行了比较,结果表明,文中提出的定期预防维修策略的维修成本最低,具有一定的推广使用价值。A periodic preventive maintenance strategy is proposed for multi-component series system. Firstly, the general model and three kinds of maintenance strategies of multicomponent series system are introduced. Next, the cost of periodic preventive maintenance is analyzed, and the optimization model is constructed. And then, the cost is minimized through genetic algorithm. Finally, through a case, the cost of the three kinds of maintenance strategies is compared. The results show that the cost of the proposed periodic preventive maintenance strategy is the lowest, and it has a certain popularization and application value.
