Abstract
A two-dimensional (2D) availability-based warranty policy is investigated from the view of the manufacturer. Under the policy, the manufacturer guarantees a negotiated availability for the products during the warranty period. In order to satisfy the availability requirement with rational cost, 2D preventive maintenance (PM) strategy is carried out, which is scheduled every K units of age or L units of usage. This study is to meet products’ availability requirement with the lowest cost by optimizing 2D PM strategy. A numerical example is provided to verify the effectiveness of the proposed policy. The results show that compared with age-based or usage-based PM strategy, 2D PM strategy is superior in terms of warranty cost and operational availability.
