摘　　要：定期维护产品的视情维修策略往往没有考虑产品的维护特点,导致处理结果无法准确反映工程需要。为此,首先根据定期维护特点,应用非齐次泊松过程描述产品失效过程,在此基础上,提出了与实际过程更为相符的维修策略;然后,通过分析定期维护产品的工作时间和维修费用,以产品生存风险为约束,平均维修费用率最低为优化目标,建立了该策略下的维修优化模型,给出了优化模型的求解算法,并进行了实例验证分析。结果表明:该维修策略可以有效地延长产品寿命并降低维修费用。The condition-based maintenance of scheduled servicing products usually doesn′t consider the servicing characteristics of products,thus it cannot reflect the true industry demand.In order to solve this problem,the failure process of scheduled servicing products is described by non-homogeneous Poisson process,and then a realistic maintenance strategy is proposed based on the servicing characteristics.Secondly,the working time and maintenance cost of a scheduled servicing product are analyzed.An optimal maintenance model is built,which aims to minimize maintenance cost rate,and is subject to product survivability probability.The algorithm of the optimal maintenance model is then provided and an experiment is also done to verify the algorithm.The calculation result proves that the maintenance strategy can prolong the product life and decrease the maintenance cost.
