摘　　要：为了客观合理地制定产品的定期维护与事后修理组合的维修策略,分析了该组合策略下产品的性能变化特点,并从失效机理出发,利用复合Poisson过程描述了产品性能退化规律,建立了以产品长期运行下费用率最低为目标的优化模型,并通过求解得到了最优的维护周期。最后,实例分析表明:该方法能够较好地描述产品的性能退化规律;同时,优化得到的维修策略值可以有效地降低维修费用,并延长产品使用寿命。In order to objectively and rationally draw up the strategies for periodic servicing and corrective maintenance, this paper analyzes the characters of performance deterioration of the products needed to be maintenanced by use of the strategies. Then the composite Poisson process is used to describe the regularity of deterioration in terms of failure mechanism so as to establish an optimization model for determining the optimal servicing period, with an objective to minimize the long-run average cost of products per time unit. Finally, a practical example is given. It demonstrates that the maintenance strategies can deal with the performance deterioration of products and meanwhile can optimally reduce the maintenance cost and prolong the service life of products.
