【摘要】：当今,产品已经实现了模块化生产和装配,产品都是由若干零部件组成。产品的耐用性使得制造企业在售出产品之后,为了提高顾客满意度、维持顾客忠诚度和提升企业品牌形象,必须维持备件库存以修复售出的产品,从而实现对顾客的售后服务承诺。同时,在传统制造业逐渐向服务业转型的大背景下,由于备件的利润率比产品利润率高的多,售后服务备件已成为很多企业追逐的利润源。技术更新换代速度加快使得产品的生命周期在逐渐缩短。企业在产品生命周期结束后,为了及时把生产线投入新产品的生产活动,会停止对原有产品所需备件的生产。但是,企业还需要持有一定的备件库存,为售后服务期内发生故障的产品提供备件更换服务。为降低服务备件的运作成本,对客户的备件需求做出快速响应,以支撑售后服务体系,有必要从停产期整体角度来制定合理的售后服务相关决策。本文研究的时间范围正是在产品生命周期结束后的停产期内。我们所研究的问题涉及到一个由备件供应商、产品生产商和消费者组成的三级闭环供应链。其中以生产商为核心,它向备件供应商订购备件,向消费者提供备件。我们研究的问题就是,如何确定停产后的产品最优售后服务时长及备件末次采购量,以使得生产商在停产期内的售后服务利润最大。本文在回顾了国内外关于服务备件末次采购、售后服务时长和停产期备件管理这三个领域的研究之后,立足于生产商售后服务利润最大,分别考虑了备件回收和生产商维修能力限制两种情况,对生产商售后服务相关决策进行了研究。具体来说,本文的核心部分如下:首先,我们分析了考虑备件回收情况下,生产商在停产期内的各项售后服务成本和收入,考虑备件是可回收的,建立了生产商的售后服务总利润模型。对模型进行求解,求得了使生产商售后服务利润最大的售后服务时长及备件末次采购量。同时,还分析了这两个关键变量随其他因素的变化情况。其次,在原有描述和假设的基础上,阐述了与原有问题的不同之处和所涉及到的新假设条件,建立了虑生产商维修能力限制情况下的生产商售后服务总利润模型。通过对模型的分析、求解,求得了此情况下决策变量的表达式。最后,进行了数值分析,不仅证实了理论研究的结论,还在此基础上做了更进一步延伸,分析了关键变量的变化规律。
[Abstract]:Nowadays, the product has already realized modular production and assembly, and the product is made up of several parts. The durability of the product makes the manufacturing enterprise to improve the customer satisfaction, maintain the customer loyalty and enhance the brand image of the enterprise after selling the product. It must maintain the spare parts inventory to repair the sold products and thus realize the customer. At the same time, in the background of the transformation of the traditional manufacturing industry to the service industry, as the profit rate of spare parts is much higher than the profit rate of the product, the spare parts have become the profit source for many enterprises. After bundling, in order to put the production line into the production activities of new products in time, it will stop the production of spare parts needed for the original product. However, the enterprise also needs to hold a certain spare parts inventory to provide spare parts replacement services for the products that have failed in the service period of service. In order to support the after-sales service system, it is necessary to make reasonable after-sales service decisions from the point of view of the whole period of production. The time range of this study is within the period of shutdown after the end of the product life cycle. The problem we study involves a closed loop supply of three levels consisting of spare parts suppliers, product producers and consumers. It takes the manufacturer as the core, which orders spare parts to the spare parts supplier and supplies the spare parts to the consumers. The problem we study is how to determine the length of the best after-sales service and the last purchase of spare parts, so as to make the manufacturers make the most profit in the after-sale service. After the study of the last purchase of spare parts, the length of service and the management of spare parts in the three fields, it is based on the maximum profit of the after-sales service of the manufacturer, considering the two conditions of the spare parts recovery and the limitation of the manufacturer's maintenance ability respectively. First, we analyze the cost and income of the after-sales service of the manufacturer under the condition of the spare parts recovery. Considering the reclaim of the spare parts, the total profit model of the producer's after service is set up. The model is solved, and the length of the after-sales service and the last spare parts are obtained. At the same time, the change of the two key variables with other factors is also analyzed. Secondly, on the basis of the original description and hypothesis, the difference between the original and the original problems and the new assumptions involved are expounded. The model of the total profit profit of the manufacturer under the condition of the manufacturer's maintenance ability is set up. In this case, the expression of decision variables in this case is obtained. Finally, the numerical analysis is carried out, which not only confirms the conclusion of the theoretical study, but further extends it on this basis, and analyzes the change law of the key variables.
