摘　　要：民机视情维修理念推动了维修向高效、经济的方向发展。本文阐述了民机视情维修的概念;研究了延迟时间模型建模原理和建模过程,提出了以维修间隔为约束、以费用率为目标的维修优化模型。针对当前中国确定民机部件维修间隔主要凭借经验的现状,进行仿真分析,并提出通过仿真机体面板的故障数据,将延迟时间模型应用于机体面板的检查与更换等维修决策中。模型以费用最低为目标、维修间隔为约束,优化了维修决策。仿真分析同时研究了不同参数条件下的最优维修间隔的变化情况。研究结果表明该方法提高了部件维修决策的合理性。Condition based maintenance（CBM）promotes the civil aircraft maintenance towards efficient and economical direction.The concept concerning CBM of broad prospects is elaborated.A CBM decision-making model namely delay time model is introduced,meanwhile,the theory and the modeling process are also researched.Presently,the inspection interval of civil aircraft′s structural component is determined mainly through experience.The delay time model is applied to the decision-making of inspection and replacement of fuselage panel with simulated failure data.The maintence decision-making is optimized with the lowest cost under the costraint of maintence interval.Furthermore,the variation of the optimal interval with different parameters is simulated.The research results verify that the method greatly increases the rationality of maintenance decision-making of components.
