Abstract

In practice, car products are sold with 2-dimensional (2D) warranty policies, on which existing literature usually assumes that the products are repaired upon failures throughout the warranty period. However, this is not always the case in real life; for example, car manufacturers may need to replace defective cars during an early period of warranty, when the total time on repairing the failures reaches a specified repair time constraint or the number of repair attempts reaches a specified repair number constraint. Motivated by this, this paper divides a warranty period into two stages: the initial protection term and the subsequent repair stage. During the initial protection term, the manufacturer needs to provide a replacement service when a specified replacement condition is satisfied; while during the subsequent repair stage, the manufacturer should provide repair services upon product failures. Taking the warranty servicing cost into account, a profit model is built. The expected total profit of the product is derived, and the optimal warranty period and product price are designed to maximize the manufacturer’s profit. Finally, numerical experiments on car examples are provided to illustrate the considered warranty policy with protection term.

考虑保护期限的二维保修政策设计
在实际销售中,汽车产品都有二维(2D)保修政策,现有文献通常假定产品在整个保修期内出现故障时都会得到维修。然而,现实生活中并非总是如此;例如,当故障维修总时间达到指定的维修时间约束或维修尝试次数达到指定的维修次数约束时,汽车制造商可能需要在保修期早期更换有缺陷的汽车。受此启发,本文将保修期分为两个阶段:初始保护期和后续维修阶段。在初始保护期,制造商需要在满足指定更换条件时提供更换服务;而在后续维修阶段,制造商应在产品出现故障时提供维修服务。考虑到保修服务成本,可以建立一个利润模型。得出了产品的预期总利润,并设计了最佳保修期和产品价格,以实现制造商利润的最大化。最后,以汽车为例进行了数值实验,以说明所考虑的带保护期限的保修政策。

期刊介绍: The International Journal of Production Economics focuses on the interface between engineering and management. It covers all aspects of manufacturing and process industries, as well as production in general. The journal is interdisciplinary, considering activities throughout the product life cycle and material flow cycle. It aims to disseminate knowledge for improving industrial practice and strengthening the theoretical base for decision making. The journal serves as a forum for exchanging ideas and presenting new developments in theory and application, combining academic standards with practical value for industrial applications.
