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
