摘　　要：针对故障小修的周期维修策略,考虑故障小修时间和预防维修时间,以部件的稳态可用度、平均费用率和平均可靠度三个指标构建一个预防维修周期的多目标最优化模型,并运用极小-极大法(min-max)求解该多目标最优化模型,从而确定出部件的预防维修周期.结合该模型给出一个算例,并通过该例阐明方法的优越性.Aimed at the periodic maintenance policy on minor trouble repair and taking account of minor repair time and preventive maintenance time,a multi-objective optimization model of preventive maintenance cycle was constructed with the steady-state availability,average cost rate,and average reliability as its indices.Then,by using ＂min-max＂ approach to solve the multi-objective optimization model,so that a preventive maintenance cycle was determined.Finally,a example was given to illustrate superiority of the method proposed in this paper.
