| The rapid development of economy and technology lead to a soaring quantity of theconsumption and waste of electronic products, which brings about resources waste and envi-ronmental pollution. Therefore, the legislation has been strengthened by governments in orderto reduce environmental pollution and improve the utilization of resources. With the growingawareness of sustainable development of people, the enterprises also focus on the recyclingand remanufacturing of waste electronic products (WEP). The study about pricing and coor-dination of the remanufacturing closed-loop supply chain about WEP under different recy-cling participant models has great significance for the reasonable pricing, coordination ofsupply chain and achieving the optimal profit.Firstly, the research background, research status, main ideas, content, methods and poss-ible innovations are introduced in the first part. Secondly, the concept of waste electronicproduct, closed-loop supply chain, as well as the recycling participant model are defined andthe theories of recycle economy theory, supply chain contract and the revenue sharing con-tract have been described. Then, three remanufacturing closed-loop supply chain models withdifferent recycling participants are established. Next, the models are solved and the pricingstrategies are compared under centralized and decentralized decision making. After that, im-proved revenue sharing contracts are designed to coordinate the three models of closed-loopsupply chain under decentralized decision making. Finally, pricing and coordination of theremanufacturing closed-loop supply chain about WEP under three different recycling partici-pant models are compared and the impact of WTP differentiation and government subsidies tothe three models are discussed by simulation example.In summary, the following conclusions are got:(1) the decisions of three different recy-cling participants models under centralized decision making are the same. And the centralizeddecision making precedes the decentralized decision making when compared from the pricing,order quantity and the total profit of supply chain. The introduction of improved revenuesharing contract can make the product pricing be lower and the profit of the supply chainachieve the optimal level of centralized decision making;(2) in the manufacturer-dominatedcase, the product pricing is lowest and the order quantity is the maximum, which is favorablefor the consumers. And the manufacturers’ profit, retailers’ profit, as well as the total profit of the supply chain are the highest when choose the model that the manufacturer is responsiblefor recycling in the three different recycling participant models, while the recovery rate islowest;(3) with the increase of the remanufactured products’ WTP, the remanufacturedproduct’s pricing in the three different recycling participant modes is increased significantlyand the recovery rate of WEP, as well as the manufacturer’s, retail’s and the recycle center’sprofits are increasing. However, the new product’s pricing will rise, which is bad for custom-ers;(4) the recovery rate of WEP will improve along with the increase of government subsi-dies. However, whether the profit of each member and the whole supply chain and the price ofproducts will grow depends on the strength of the government subsidies and the choice ofdifferent recycling participant models. The possible innovations of this paper: Three differentrecycling participant models with participants of state, manufacturers’ league and manufac-turer have been studied and the uncertain demand of market and the different WTP of prod-ucts are considered. The impact of the government subsidy has also been discussed. But thisarticle does not take the various recycling channels into account.The results showed that: the improved revenue sharing contract can reduce the products’price and increase the profit of the members of supply chain. Government and the members ofthe supply chain can raise the recovery rate of WEP and increase the profit of the supply chainthrough promoting the remanufactured product’s WTP, while the products’ price will rise atthe same time. The increase of government subsidies can improve the recovery rate of WEP,but should be controlled in a reasonable range. |
