针对现有文献对视情维修的研究忽略了设备检测时间的问题，建立一种基于Gamma过程的视情维修的解析模型。以维修费用为目标函数求解获得了设备的最优预防维修阈值和最优检测间隔，对设备的劣化状态进行描述并对维修过程建模，在该解析模型下，通过大量的数值仿真，分别比较分析了设备劣化状态变化特性以及维修能力对视情维修最优策略值选取的影响，并获得了相应的结论。仿真算例证明了该方法的可行性，可为维修方选取最优策略值提供一定的参考。

For some product that the detect time can’t be neglected, the analytical model of condition-based maintenance was built based on the Gamma process. The optimal preventive maintenance threshold and inspect time were decided through optimizing the maintenance cost. The simulation example was proposed based on the model. It analyzed the effect of the character of product deteriorating state and maintenance ability on the maintenance strategy. Some relevant conclusions were obtained. The simulation example shows that the method is feasible and can serve as the guidance for maintenance strategy.
