Study Of Game Model On Waste Electronic Product Recycling Process

Entering the 21st century,with the rapid development of science and technology,the life cycle of electronic products gradually shortened,more and more discarded electronic products,waste electronic products will cause harm to the environment and waste of resources.At the same time,the face of resource and environmental issues,the Government’s sustainable development and environmental awareness is gradually increasing,developed a series of laws and regulations and policies to promote the recycling of used electronic products recycling.Therefore,vigorously develop the circular economy and promote the recycling of waste electronic products,recycling has become a strategic issue for electronic enterprises.Waste electronic products recycling and recycling First of all we must solve the waste of electronic products recycling,that is,research and recycling of waste electronic products channels.Therefore,it is important to identify the key influencing factors in the presence of waste E-Recycling.In this paper,the factors that affect the recycling of discarded electronic products are firstly extracted,and the key factors are identified by gray number-DIMATEL:the recycling enterprises and the waste electronic processing enterprises lack effective cooperative mechanism,and the national environmental protection and recycling consciousness are weak.In the past,there has been a great deal of research on the mechanism of cooperation,but the fairness factor plays a vital role in developing and maintaining the channel partnership.On the other hand,the state in order to promote recycling of used electronic products,promulgated a series of laws and regulations.Although the state of these laws and regulations to a certain extent,promote the recycling of used electronic products,but in order to fundamentally solve the national environmental protection and recycling awareness of this constraint,we must think of improving consumer awareness of environmental protection,effective The way is to carry out waste recycling e-publicity.Recycling of waste electronic products for recycling,the need for a certain amount of recycling publicity costs,the expense of who is a need to address the problem,because the different commitment to the recycling efforts will result in changes in the level of the same time,need to further analysis of recycling of waste electronics Product recovery short-and long-term effects.In this paper,based on the existing literature and related theories,this paper constructs an evolutionary game model of processor and recycler based on fairness concern,and uses system dynamics simulation to analyze the effects of different strategies of the processor and the recycler on the recycling of used electronic products Secondly,the static game model of recycler and recycler is constructed based on the recycling propaganda,and the effect of the different commitment modes on the recycling propaganda is analyzed.Furthermore,the coordination mechanism is given in order to optimize the recycling channel.,In order to analyze the long-term impact of recycling propaganda on discarded electronic products,a differential game model of processors and recyclers was constructed based on recycling propaganda,and the influence of recycling publicity on recycling of used electronic products was analyzed from the dynamic point of view.The main results are summarized as follows:Firstly,it identifies the key factors that restrict the recycling of discarded electronic products,and introduces the fairness concern for the cooperation mechanism,and establishes the game model of the dealers and recyclers under the fairness concern.On the basis of this model,it is considered that the fairness is not taken care of by the dealership and the recycler,the fairness of the recycler,the fairness of the recycler,the fairness of the dealer and the recycler.This paper analyzes the impact of fairness concern on the recovery price,quantity of recycling and profit of waste electronic products.Furthermore,an evolutionary game model is constructed based on the above four conditions in order to obtain the final strategic choice of fairness concerns between the handler and the recycler.It is concluded that the fairness concerns of the processors will reduce the unit’s indirect/direct recovery prices,the number of recyclers and the profits of the recyclers,and the profits of the processors will increase.When the fairness concern is adopted,the unit will directly recycle the price,the profits of the recycler will increase,but the profit of the processor will be reduced,and the quantity will not be affected.After a long evolutionary game,the evolution equilibrium is one of the fairness concerns.Secondly,in order to analyze the effect of different commitment ways on the recycling channel from the static point of view,a game model of recycler and recycler is established.Based on this model,the changes of the recycling channel decision-making variables are compared and analyzed,and in order to optimize the recycling channels as a whole,the supply chain coordination contract.The results show that the recycling quantity and profits of waste products are increased,even though the unit recovery price and unit indirect recovery price are reduced.Recycling promotion policy can improve consumers’ environmental awareness,promote the enthusiasm of consumers to recycle waste products,so that the direct recovery price of used products can be returned to the market price;for the reverse supply chain coordination,the two charge contract and cost sharing contract can not So that the supply chain to achieve coordination,restrain the recovery of indirect recovery of the price of the cost-sharing contract can reverse the supply chain to achieve coordination.Finally,in order to analyze the long-term effect of recycling propaganda on recycling of discarded electronic products,a recycling game model is established.Furthermore,in order to analyze the impact of recycling efforts on recycling channels,recyclers are introduced to collect variables,Recycling and Recycling Differential Game Model for Promotion and Recovery.Based on the above model,the influence of different commitment modes on the differential system is contrasted and analyzed.Furthermore,the supply chain coordination contract is given in order to realize the upstream and downstream joint recovery.When the recycler undertakes the cost of recycling,the recycler is mainly responsible for the recovery of the recycling quantity.When the recycler is responsible for the recycle,the recycler is responsible for the recycling cost.The recycling unit can directly recover the price by increasing the unit recovery price,and the recycle promotion channel can be coordinated as long as the indirect recovery price coefficient of the constraint unit satisfies a certain proportion.
