摘　　要：保修期内进行预防性维修可以降低厂家保修费用,提高产品的可用度,延长产品使用寿命。老化产品的维修通常是不完全维修:产品维修后不能达到修复如新状态,但是故障率降低。假设产品经预防性维修后故障率恢复到某一特定值,以保修费用为目标建立基于改善因子的不完全预防性维修模型,并通过实例确定保修费用最低时的最佳维修间隔期。Preventive maintenance in warranty period could reduce warranty cost, improve availability of product, and prolong the life of product. The maintenance of a deteriorating product is often imperfect： the product after maintenance will be not as good as new, but younger. On the assumption that the failure rate of product after maintenance will improve to a fixed value, it built imperfect preventive maintenance models of the products using improvement factor. According to an example, optimal interval making cost minimization can be calculated.
