Abstract

An optimal age-replacement policy under renewing free-replacement warranty for non-repairable products is considered. Upon failure, it incurs a downtime. Such downtime cost can have a significant impact on users’ profits/safety. The users will have to decide when to replace the product. Taking product warranty into account, different decisions will have different cost implications to users. For products with a bathtub failure rate function, and considering a discounted purchasing cost, we derive the expressions for the long-run expected cost rate. Then the optimal age-replacement policy is obtained. It shows that the optimal replacement age should be adjusted toward the warranty period when a product is warranted.
