Research On Reverse Logistics Network Of End-of-life Vehicles Based On EPR

With the development of China's economic, the number of end-of-life vehicles increases as fast as the auto production and sales amount. ELV recycling is not only related to the transportation security, but also involves the environmental protection and efficient use of resources and so on. With the shortage of resources and environmental pollution becoming increasingly serious, developing circular economy and carrying out reusing of resources have been widely accepted, the importance and the effectiveness of ELV reverse logistics have been also concerned by the society. So, the paper researched the end-of-life vehicles reverse logistic network.Firstly, by studying the ELV recycling status at home and abroad, the paper proposed that there were some problems in our ELV reverse logistics, which were the low rate of recycling and recovery and serious environmental pollution. By analyzing the reasons and drawing on foreign experience, the implementation of the EPR (extended producer responsibility) was proposed to solve these problems.Secondly, this paper constructed a ELV reverse logistics network based on the EPR, and then created a network optimization model to determine the number, scale, location of the recycling centers and the logistics flow distribution by taking both cost and recycling rate into consider. Through studying an example, we found the variation regularity of cost with the change of recycling rate, and proposed the enterprises'measures at different levels of recycling rate.Last, to ensure the efficiency of the ELV reverse logistics network and promote the effective implementation of EPR, the paper improved the operating mode of the logistics network. On the base of the existing researches, the paper analyzed the advantages and disadvantages of the MT mode, PT mode and TPT mode, then designed an improved mode of the automotive manufactories cooperating the existing ELV recycling enterprises by co-financing. The advantages of this mode had been analyzed. The quantitative comparison showed that this mode could create higher economic benefits and recycle more end-of-life vehicles. All of these can ensure the reverse logistics network operating efficiency and effectively promote the implementation of the EPR.
