Research On Reverse Supply Chain Of Waste Electrical And Electronic Products Recycling Based On Incentive Strategies

The development of technology and modern industry results in a huge amount of waste electrical and electronic products, leading to serious problems of environmental pollution and resource waste. Therefore, many countries developed related mandatory law and regulations on waste recycle. Some companies also realize the hidden value and begin to conduct recycling and reusing operations. However, due to the current disordered recycling market, the lack of environmental awareness of consumers and low enthusiasm of manufacturers, there are considerable difficulties for enterprises to conduct recycling and remanufacturing operations. Therefore, it is critical to build the recycling reverse supply chain based on incentive strategy.Firstly, the incentive mechanism of the reverse recovery supply chain is analyzed qualitatively. After clearing reasons that incentives are necessary for reverse supply chain system, and comparing the features of different responsibilities, several specific incentive policies are proposed and discussed from the aspects of advantages, applicability and standards.On the basis, according to the structure of reverse supply chain, quantitative researches are focus on incentive strategies to the "consumer-recycler" reverse supply chain and the "recyclers-manufactures" reverse supply chain. For the "consumer-recycler" reverse supply chain, the models of price discounts strategy and deposit refund strategy are built. And an improved deposit refund model evolving demand damage and investment income of deposit are constructed as well. The profits fluctuation and recovery quantities fluctuation are examined so as to verify the effectiveness of these two kinds of strategies. By searching for the optimal solution and the critical solution, effective ranges of strategies are determined, which give some inspirations for companies to develop appropriate recovery strategies.For the "consumers-recyclers" reverse supply chain, in addition to the model without deferred payment policy, deferred payment policy models Ⅰ under manufacturer leading and deferred payment policy models Ⅱ under cooperation are constructed. The optimal remanufacturing rate and optimal replenishment times are solved and their relationships between different models are concluded as well. And then the effectiveness of deferred payment policy, the impact of different degrees of cooperation, as well as the impact of changes in deferred payment period for each stakeholder are analyzed and compared, which provide several management enlightenments.
