customization two-dimensional extended warranty preventive maintenance usage rate purchasing date warranty cost
To increase customers’ satisfaction and promote product’s competitiveness, a customized extended warranty(EW)policy is proposed, where the diversities in both the usage rate and purchase date are considered. The marginal approach is applied to describe the product’s two-dimensional failure in terms of age and usage, respectively. Moreover, minimal repair is adopted to restore the failure, and the virtual age method is applied to depict the effect of preventive maintenance(PM). On this basis, an optimization model is established to minimize the maintenance cost and warranty cost from the manufacturer’s view, and multiple factors are taken into account, including the PM’s intensity and its period, and EW’s interval, etc. A numerical case study is provided to illustrate the effectiveness of the proposed approach. The results show that by considering the product’s usage rate and the purchasing date of EW, the number of failures as well as the cost of maintenance and warranty can be reduced effectively.
