首发时间:2020-12-09
摘要:近年来,随着社会经济的发展和人们环保意识的提高,二手产品市场受到广泛的关注。由于缺乏对二手产品历史使用情况的了解,消费者对二手产品可靠性存在顾虑。经销商通过提供质保服务向消费者提供质量保证。准确评估二手产品的可靠性,控制质保成本是经销商十分关心的问题。当前对于二手产品的质保研究大多假设具有相同使用年龄的产品可靠性相同,本文考虑二手产品可靠性的差异性,结合历史失效数据利用贝叶斯原理计算二手产品的可靠性。文章研究可靠性差异性对质保成本的影响,讨论了针对具有不同失效历史的二手产品如何制定适当的质保政策降低质保成本。

Research on Warranty Cost Model of Second-hand Products Based on Historical Maintenance Data
Abstract:In recent years, with the development of social economy and the improvement of people\'s awareness of environmental protection, the second-hand product market has been widely concerned. Due to the lack of understanding of the historical use of second-hand products, consumers have concerns about the reliability of second-hand products. Dealers provide quality assurance to consumers by providing quality assurance services. How to evaluate the reliability of second-hand products accurately and control the cost of quality assurance are very concerned by dealers. At present, most of the researches on the quality assurance of second-hand products assume that the reliability of products with the same age is the same. This paper considers the difference of reliability of second-hand products and calculates the reliability of second-hand products by using Bayesian principle combined with historical failure data. This paper studies the influence of reliability difference on quality assurance cost, and discusses how to formulate appropriate quality assurance policy for second-hand products with different failure history to reduce the quality assurance cost.
