Based on the product characteristics of waste electrical and electronic equipment (WEEE), considering the uncertainty of market demand, the demand is fuzzed, and a closed-loop supply chain (CLSC) is established under the guidance of retailers, in which the government implements reward and punishment policies for manufacturers, retailers and third-party recyclers respectively, and with the use of game theory, decision variables change based on government's rewards and punishments in the three recycling pricing models. The results show that the wholesale price of goods is the lowest and the recycling rate of waste products is the highest under the manufacturer recycling mode, and the manufacturer's revenue is far greater than the retailer's revenue, which provides reasonable suggestions for the supply chain management of manufacturing enterprises.
