Abstract: This paper takes end of life(EOL)product recycling as the research object, quantitatively analyzes the decision making problem of low commercial value and high environmental impact EOL products. Through the construction of EOL product dual closed-loop supply chain and multi closed-loop supply chain model, the EOL product recovery strategy of each model is solved and compared with the traditional single closed-loop supply chain, which proves that the closed-loop supply chain is superior to the traditional single closed-loop supply chain. It is found that, under the conditions of government supervision and subsidy intensity, and the same external market variables, the EOL product recovery of the multi closed-loop supply chain is greater and the recycling is more fully utilized. And with the increase of the number of external circulation of the multiple closed-loop supply chain, both the recovery of EOL products and the profits of the recyclers increase, and the profits of the internal circulation manufacturers are also in the same way. In addition, the profit of the seller is not affected. Finally, an example analysis of the multi closed-loop supply chain is carried out, and the above conclusions are verified. It provides a reference for the government to make a better use of supervision and subsidy to allocate market resources.
