【摘要】：随着产品生命周期日渐缩短和产品更新换代日趋频繁,废旧产品日益增加,已严重威胁到人类赖以生存的环境。对废旧产品进行回收再制造,不仅能够减少浪费和降低对原材料的需求,使得生产活动变得更加绿色环保；而且可以降低生产成本,提高企业的经济效益。由于科学技术的快速发展,市场竞争越来越激烈,制造商不得不提供更长的保修期。产品保修作为售后服务的重要组成部分,变得越来越重要,保修可以保证产品在损坏时,购买者得到相应的赔偿或维修服务。本文对单一制造商和单一零售商组成的供应链系统,基于博弈理论研究了在免费保修策略下,制造商回收模式、零售商回收模式和第三方回收模式的构建和再制造产品的定价问题。定价策略包括单一定价即再制造产品与新产品价格相同,和差异化定价即再制造产品与新产品价格不同。探讨了新产品和再制造产品的定价策略和产品保修是如何影响回收渠道的选择,比较分析了新产品和再制造产品的保修期。文章主要研究内容如下：首先介绍了本文研究的背景及意义,然后简要说明了文章的主要研究思路及整体结构,并介绍了本文的贡献。其次对国内、外逆向物流回收渠道的设计,新产品和再制造产品的定价策略,产品的基本保修及延长保修等相关文献进行了综述,指出了现有研究中存在的问题。然后在免费保修策略下,新产品和再制造产品统一定价,研究了不同回收渠道对新产品和再制造产品的保修期、废旧产品的回收率、产品价格及供应链渠道成员利润的影响,对结果进行了比较分析,探讨了规模参数对决策变量的影响。最后在免费保修策略下,新产品和再制造产品差异化定价,研究了不同回收渠道对新产品和再制造产品的保修期、废旧产品的回收率、产品价格及供应链渠道成员利润的影响,对结果进行了比较分析,分析了相关参数对决策变量的影响。通过研究发现,不管是单一定价还是差异化定价,在不同的回收模式中,新产品的最优基本保修期都相等,再制造产品的最优基本保修期都相等。新产品和再制造产品的最优基本保修期跟单位时间内的平均维修成本与单位时间内损坏的可能性成反比。若单一定价时满足fr≤fnλnξr/λrξn,差异化定价时满足fr≤fnλnμr/λrμn,则再制造产品的基本保修期就不会低于新产品的保修期。在单一定价策略下,当SG≤3+√6/3S时,最有效的回收模式是制造商负责回收；当G3+√6/3S时,零售商进行回收是最有效的回收模式,但最无效的回收模式是第三方进行回收。降低再制造产品的保修相关成本,不仅能够提高废旧产品的回收率,而且可以增加制造商的利润。在差异化定价策略下,最有效的回收模式是制造商负责旧产品回收。产品的需求,回收率,制造商利润和供应链利润在制造商回收模式中都是最大的。随着消费者对再制造产品支付意愿的提高,产品的回收率和供应链利润都显著增加,这可以减少废旧产品对环境的污染和提高制造商的利润,因此制造商应该加大对再制造产品的宣传力度。
[Abstract]:As the life cycle of the product is shortening day by day and the replacement of product is becoming more and more frequent, the waste products are increasing, which has seriously threatened the environment of human survival. Recycling and remanufacturing of waste products can not only reduce waste and reduce the demand for raw materials, make production activities more green and environmentally friendly, but also reduce life. With the rapid development of science and technology, the market competition is becoming more and more intense, and the manufacturer has to provide a longer warranty. As an important part of the after-sales service, the product warranty is becoming more and more important. The warranty can ensure that the buyer receives the corresponding compensation or maintenance service when the product is damaged.
In this paper, a supply chain system consisting of a single manufacturer and a single retailer, based on the game theory, the manufacturer recovery mode, the retailer recycling model and the third party recycling model and the pricing of remanufactured products are studied. The pricing strategy includes a single price, that is, the remanufacturing product and the new product price. The pricing strategy of the new products and remanufactured products and the product warranty are how to influence the selection of the recycling channels, and the warranty period of the new products and remanufactured products is compared and analyzed.
The main contents of the article are as follows:
First, it introduces the background and significance of this study, then briefly describes the main research ideas and the overall structure of the article, and introduces the contribution of this article.
Secondly, it summarizes the domestic and foreign reverse logistics recycling channel design, the pricing strategy of new products and remanufactured products, the basic warranty and extension of the warranty and other related documents, and points out the existing problems in the existing research.
Then, under the free warranty strategy, the new product and remanufactured product are fixed in uniform pricing. The effects of different recycling channels on the warranty period of new products and remanufactured products, the recovery rate of waste products, the price of product and the profit of the supply chain channel members are studied, and the effects of the scale parameters on the decision variables are discussed.
Finally, under the free warranty strategy, the pricing of the new products and remanufactured products is differentiated. The effects of different recycling channels on the warranty period of new products and remanufactured products, the recovery rate of waste products, the price of products and the profit of the supply chain channel members are analyzed, and the effects of the related parameters on the decision variables are analyzed.
Through the study, it is found that the optimal basic warranty period of the new product is equal in the different recovery modes, regardless of the single pricing or differential pricing. The optimal basic warranty period of the remanufactured products is equal. The average maintenance cost of the new and remanufactured products is with the average maintenance cost in the unit time and the damage within the unit time. The possibility is inverse ratio. If the price satisfies fr < FN lambda n r/ lambda R n, the differential pricing satisfies fr < FN lambda n r/ lambda r Mu n, then the basic warranty period of the remanufactured product will not be lower than the warranty period of the new product.
Under a single price strategy, the most effective recovery mode is the manufacturer responsible for recycling when SG < 3+ 6/3S. The most effective recovery mode is the retailer recycling when G3+ 6/3S, but the most invalid recovery mode is the recovery of the third party. Reducing the warranty related costs of remanufactured products can not only improve the recycling of waste products. Rate, and can increase the profit of the manufacturer.
Under the differential pricing strategy, the most effective recovery mode is that the manufacturer is responsible for the recovery of the old products. The product demand, the recovery rate, the manufacturer's profit and the supply chain profit are the largest in the manufacturer's recovery mode. With the increase of the consumer's willingness to pay for Remanufacturing products, the recovery rate of the product and the profit of the supply chain are significantly increased. It can reduce the pollution of the waste products to the environment and increase the profits of the manufacturers. Therefore, the manufacturer should increase the publicity for remanufacturing products.
