由于废旧产品处理量的增加，寿命终止（EOL）管理已引起制造商的高度关注。关键问题之一是再制造产品的可靠性和质量。为了提高消费者满意度，保修服务管理必须为其产品的使用寿命提供某种质量保证。然而，较高的保修价格标签通常可能会降低消费者的购买力，因此制造商需要为其制造的产品确定适当的价格标签，以获得显着的市场竞争力。本文提出了数学模型来检验制造商提出的两种类型的延长保修政策，以比较制造商再制造产品可能获得的利润。优化模型通过顺序二次规划进行数值求解。数值示例的结果表明，制造商的具有时间因素的保修类型 I 政策通常比具有实施失败计数的保修类型 II 政策更可取。
Due to an increase of the used product disposal, the end of life (EOL) management has drawn significant attention by manufacturers. One of the critical concerns is the reliability and quality of the remanufactured product. In order to increase consumer satisfaction, the warranty services management has to provide sort of quality assurance for its product post-use life. However, higher warranty price tags may often reduce consumers' purchasing power and, therefore manufacturers need to determine the appropriate price tags for their manufactured products in order to gain significant market competitiveness. This article presents the mathematical models to examine two types of the proposed extended warranty policies for manufacturers to make the comparisons of their possible gained profit of remanufactured products by manufacturers. The optimization models were numerically solved by sequential quadratic programming. An outcome of the numerical example showed that manufacturer's warranty type-I policy with time factor was generally more desirable than warranty type-II policy with failure counts for implementation.
