Customized Preventive Maintenance Strategies for Products Sold with Two-Dimensional Warranty

Two-dimensional warranty has played a significant role in improving product quality and competitiveness. However, two-dimensional basic (BW) extended (EW) have not yet been combined effectively, the customized maintenance strategies based on consumers’ heterogeneity quite limited, which result high costs. In this paper, possibility of reducing cost over BW EW is explored by classifying customers their usage rates then offering them with preventive (PM) strategies. By considering purchasing ratio contracts, PM for are closely bi-level programming model. Numerical analysis given to show application proposed strategy, findings sensitivity main parameters analyzed end. The demonstrate that combining can effectively reduce costs within period provide scientific guidance manufacturers design more reasonable strategy.
