摘　　要：针对产品保证服务成本持续上升的问题,将预防性维修与修正性维修有效集成,提出了考虑预防性维修的二维延伸产品保证策略,建立了以保证服务成本最小为目标的保证服务成本模型,并对不同使用率下的保证服务成本进行优化以确定最优的保证策略。采用数值分析方法将其与最小维修策略进行对比,结果显示保证服务成本有了显著的降低。Due to the problem of rising warranty service cost,the preventive maintenance and the corrective maintenance were integrated; and a new two- dimensional warranty strategy considering the preventive maintenance was proposed to solve this problem. A mathematical model of warranty cost was developed to minimize the warranty cost. The optimal warranty strategy was derived to optimize the warranty cost based on the different usage rates. Finally,numerical analysis was compared with the cost of minimal repair strategy. The results indicate that the warranty cost is reduced significantly.
