摘　　要：基于更新过程理论,运用更新极限定理给出部件“稳态可用度”“长期运行单位时间的期望维修费用”和“平均可靠度”的推导过程,通过理想点法中的极大模理想点法来构建以稳态可用度、长期运行单位时间的期望维修费用和平均可靠度为目标函数、以预防维修周期为决策变量的多目标预防维修优化模型,最后通过算例分析计算显示,运用所构建的模型方法能有效地求出符合需求的预防维修周期。Based on the renewal process,the deduction procedure of steady state availability,average spending rate for long-time running and average reliability were given by using renewal limit theorem.A multi-objective optimization model with steady state availability,average spending rate for long-time run⁃ning and average reliability as the objective function and preventive maintenance cycle as the decision variable is constructed by the maxima module ideal point method.By the method proposed in this paper,the optimal preventive maintenance cycle can be get.
