电子类产品回收再制造能力与二手市场需求相协调的研究——以电视机为例

Study on the Coordination between Collection and Remanufacturing Capacity and Demand of Secondary Marke——The Case of TV Set

本文研究了再制造电子产品在二手市场进行销售的问题,以电视机为例,探讨了电视机制造商如何在"生产者延伸责任制"及其它环保政策影响下建立回收再制造设施体系及其动态扩张:首先用系统动力学(SD)方法建立开环结构下再制造逆向供应链系统的仿真模型,然后根据二手市场的两种需求情况分别模拟该系统的长期动态行为,并对设施扩建的相关参数对总利润的影响进行了灵敏度分析。结果表明:当二手市场需求较大时,厂商采取超前的设施扩张策略会获得较大的规模效应,利润更高;而当二手市场需求较小时,规模效应则不够明显。最后结合我国的实际情况进行了分析。另外,本文的系统动力学模型具有一定的普适性,可以在其他的电子类产品中进行推广。

This paper studies the sales of remanufacturing electronic products in the second market for the case of TV set. We explore into the problems that how TV manufacturers build the collection and remanufacturing facility systems and their dynamic expansions under the influence of ＂extended producer responsibility＂ and other environmental protection policies. Firstly a simulation model of open loop remanufaeturing reverse supply chain system is built based on System Dynamic （SD） methodology. Then according to two cases of secondary market＇s demand the long-term dynamic behaviors of the system are simulated respectively and the sensitivity analyses that the influence of parameters related to facility expansions on the profits are given The results indicate that the larger scales of economy and more profits can be achieved when the secondary market＇s demand is higher, whereas the scales of economy are not obvious when the secondary market＇s demand is lower. Lastly we analyze the model combined with reality of China. Furthermore, to a certain extent, the SD model is universal and can widely be applied in other electronic products.
