摘要
运用役龄回退因子的概念 ,建立了预防性维修前后故障率的递推关系 ,并以故障时间分布符合威布尔分布的设备为例 ,构建有限时间区间的预防性维修策略的优化模型 ,克服了无限时间区间优化模型不可操作的缺点 .
The recursion relationship of the failure rate before and after preventive maintenance(PM) was built up concerning with the concept of age reduction factor. And the optimal PM policy model in finite time horizon of the equipment following Weibull distribution was proposed. This approach avoids the shortcoming of the mathematical model in infinite time horizon and can be used for scheduling the maintenance plan and providing the decision supporting for job shop scheduling.
