摘　　要：研究了具有修理延误情况的产品维修决策问题,运用概率和随机过程原理建立了产品故障模型和寿命周期费用模型。提出了以经济性为目标的检查与修理优化策略,分析了功能检查间隔期最优解的性质。该模型适用于分析在非周期性检测条件下的维修策略,可同时优化检查间隔期和修理延误时间。提出了一种基于迭代的优化算法,给出了应用该方法的具体步骤,并通过示例说明了该模型的求解过程和算法的有效性。The problem of decision-making on functional inspection for a component with delayed repair is studied. The models of failures and life cycle cost are developed using probability and stochastic process. An optimal policy of inspection is presented with an economic objective, and the property of solution to the intervals of inspection is studied. The model is applicable to analyze maintenance policy under non-periodic inspection, and optimize the inspection intervals and the delay of repair together. An algorithm for optimizing the policy is presented using the method of iteration, and procedure for using the methodology is also presented. At last, an ex ample is given to show the process of solving the problem and verification of the algorithm.
