摘　　要：通过对相关文献的研究,提出采用使用时间和使用程度二维变量把产品保证区域划分成三个子区域,对第二个子区域里发生的第一次故障采用缺陷维修策略,对在第一、第三个保证子区域里发生的故障和在第二个保证子区域内第一次故障后的所有故障都采用最小维修策略;通过建立该产品保证策略下产品保证成本模型并获得优化处理的结果,又与相关文献所提供数例处理结果比较后发现:当故障产品最小维修费用相对于更换维修费用较小时,本文提供的产品保证策略方案更优。A two-dimensional warranty strategy based on minimal and imperfect repairs was studied. A warranty region which was described in terms of two measures （age and usage） was divided into three disjoint sub-regions. The failed item was rectified by imperfect repair when it fails for the first time in the second sub-region of the warranty and all other failures are repaired minimally. Moreover,the model of total expected warranty servicing cost was built and analyzed under this strategy. Finally, using an illustrative numerical example and comparing with other strategies studied in the earlier literature, the paper shows that when the cost of a minimal repair is low compared to the cost of replacement, then this strategy is more appropriate.
