维护是保持产品技术状态、降低失效发生的重要手段。通过分析维护对产品技术状态和失效变化规律的影响,利用复合Poisson过程描述了产品的维护效果,得到了定期维护条件下产品的寿命分布规律。在此基础上,提出了一种定期维护与视情维修相结合的维修策略,通过优化该维修策略下的产品维修费用,给出了最优的定期维护周期和预防性维修阈值。通过算例分析,表明该维修策略可以有效延长产品的维修间隔,从而大大减少产品全寿命期间的维修次数,产品在全寿命周期内的维修费用也得到了有效降低。

Servicing is seen as an important means to retain product state and lower failure frequency. This study analyzes the impact of servicing on product state and failure rule. The composite Poisson process is used to model the servicing effect, so as to obtain the life distribution of a product for the case of scheduled servicing. Based on the life distribution, a maintenance strategy is proposed which combined the benefits of scheduled servicing and condition-based maintenance. The optimal servicing period and preventive maintenance threshold are determined through optimizing the operation cost in the maintenance strategy. Finally, the simulation result shows that this maintenance strategy can prolong the product time between maintenances, so that the number of maintenances can be considerably reduced in its whole life cycle. It also shows a great decrease on the whole life cycle maintenance cost.
