摘要: 针对由供应商提供的关键部件引发的大型装备产品故障,提出对上述关键部件进行预防性维修费用投资的保修策略。通过建立投资预防性维修的费用模型,获得顾客与制造商、制造商与供应商的投资预防性维修的双赢区间,并通过理论和数值分析,研究故障率和各种费用对双赢区间和三赢区间的影响,进而得出最优预防性维修策略、最优双赢区间和最优三赢区间。结果表明,投资保修期内的预防性维修费用的保修策略适用于大型装备产品,该产品中由供应商提供的关键部件的故障率越高,故障后维修时间越长,对其实施预防性维修的费用越低。

关键词: 多部件大型装备产品, 关键部件, 预防性维修, 保修策略

Abstract: To prevent the failure of large equipment products caused by key components provided by suppliers, a warranty strategy to invest in the preventive maintenance costs for such key components is proposed. By establishing a cost model of investing in preventive maintenance, the win-win interval of preventive maintenance investment for the customer and the manufacturer, as well as for the manufacturer and the supplier, is obtained. The effects of failure rate and various costs on the win-win interval and tri-win interval are investigated through theoretical and numerical analysis, leading to the optimal preventive maintenance strategy, optimal win-win interval and optimal tri-win interval. The results show that the warranty strategy of investing in the cost of preventive maintenance during the warranty period is applicable to large equipment products, where the higher the failure rate of key components provided by the supplier and the longer the repair time after failure, the lower the cost of implementing preventive maintenance.

Key words: large equipment product with multiple components, key component, preventive maintenance, warranty strategy
