摘　　要：在(s,Q)的故障替换概率分布模型基础上,提出了基于最小补充周期效用的优化补充周期定义算法和基于最小订货周期效用的优化订购周期定义算法,在保持了(s,Q)机制强调费用节省和可用性优点的同时,克服了它对资金积压、技术折旧损失和缺货损失、冗余库存维护损失缺乏调控能力的缺点.仿真结果很好验证了本机制的优点.Based on the probability distribution model of fault replacement of（s,Q）,an optimal replenishment cycle algorithm targeted to minimize the replenishment cycle utility and an optimal ordering cycle algorithm targeted to minimize the ordering cycle utility are introduced,they not only keep the saving expense merit and the improving availability merit in（s,Q）,but also overcome the disadvantages of lacking of adjusting ability to overstocking of capital losses,device deprecation losses,the shortage loss and the surplus maintenance losses.The simulation result verifies our mechanism merits well.
