A Bivariate Post-Warranty Maintenance Model for the Product under a 2D Warranty

In this study, by integrating preventive maintenance (PM) into a two-dimensional warranty region, with customized PM (2D PM) is proposed from the manufacturer’s perspective to reduce cost. The cost of 2D derived. tradeoff between and minimal repair saving obtained choosing proper reliability threshold number PMs, advantage illustrated. Second, post-warranty period, bivariate (BPWM) policy consumer’s ensure product through PM. expected rate model BPWM Optimal in numerical experiments. It shown that beneficial for both manufacturer consumer, since total are reduced.
