Research On The Coordination Of Closed-loop Supply Chain In Electronic Products Industry Under The Influence Of Promotion Efforts

With the continuous progress of social technology,the production speed of electronic products is faster and faster,the life cycle is also gradually shortened,and people change electronic products faster and faster.In fact,although electronic products are constantly updated,many parts and modules in electronic products have not been completely eliminated,and only a few innovative modules and components have been replaced.Therefore,considering the recycling of waste electronic products is very economic and social benefits.With the continuous development of the Internet,e-commerce is also more and more prosperous,the scale of online consumption is more and more large,and the network channel has become an important aspect in the research of electronic product supply chain coordination.There are many methods of supply chain coordination,among which contract coordination is a common method.Through contract,the relationship between members of supply chain can be coordinated,the conflicts and conflicts of interest among members can be alleviated,the reasonable distribution of interests can be realized,and the operation efficiency of supply chain can be improved.In this paper,literature analysis,comparative analysis,mathematical analysis,case analysis and Stackelberg game analysis are applied.Based on the analysis of the theory of electronic products and supply chain,the coordination of single channel electronic products supply chain based on promotion effort is analyzed by using the reverse induction.It is found that promotion effort level and sales price affect the market at the same time In the case of market demand,the supply chain can not reach the coordination state under decentralized decision-making;however,under the revenue sharing cost sharing contract,each decision variable in the supply chain can reach the optimal value under centralized decision-making,and the one-way single channel electronic product supply chain can reach the coordination state.Secondly,further research on the closed-loop electronic product supply chain with waste electronic product recycling stations is carried out.It is found that the uncoordinated level of recycling efforts will have a great impact on the cost and income of the supply chain.By introducing the cost sharing coefficient of recycling efforts,the improved revenue sharing contract can improve the level of recycling efforts and reduce the production of the electronic product supply chain Cost,improve the efficiency of supply chain.Finally,in the supply chain model,the influence of the sales price and promotion effort level of the network channel on the market demand is further increased,and the competition factors of the promotion effort between the channels are also taken into account,so that the model is more in line with the reality and enhances the applicability of the model.Through the establishment of two-way revenue sharing contract,the closed-loop dual channel electronic product supply chain is coordinated.Finally,the promotion efforts between channels and the total revenue of the supply chain are improved,and the supply chain coordination is realized.
