　　运用故障率衰减模式对退化设备的预防维修策略进行研究，建立了一种新的预防维修模型。考虑到故障小修对整个预防维修时间的影响，引入了设备完好率的概念，以单周期内的设备完好率为约束条件，建立了一个以设备更新周期内单位时间平均维修费用为目标函数的优化模型，来求解使维修费用最低的最优预防维修周期以及最优预防维修次数。运用 MATLAB 软件进行了数值验证，验证结果表明模型可以有效地找出在不同设备完好率要求下的最优预防维修策略。

A new equipment preventive maintenance model is established to study the preventive maintenance strategy of degraded equipment based on the failure rate decay model. Considering the influence of the minor repair time for the preventive maintenance time, the concept of the integrity rate of equipment is introduced. By the constrains of the integrity rate of equipment within a single-cycle, an optimization model of the equipment was established to study the average maintenance cost per unit time in an up-date cycle to solve the lowest maintenance costs with the optimal preventive maintenance period and the optimal number of pre-ventive maintenance . MATLAB software is used for the numerical verification. The verification results show that the model could find out the optimal preventive maintenance strategy under the different integrity rate of equipment.
