Research On Decision-making Of Automobile Hybrid Recycling Mode In Closed-Loop Supply Chain Under Different Channel Power

With the year-by-year increase in the number of cars in my country and the gradual end of the life cycle of each car,there are a large number of scrapped cars on the market,so how to dispose of used cars and reduce the impact on the environment has attracted more and more attention.Due to the abundant resources contained in used cars,if not effectively recycled,it will cause huge environmental pollution.With the development of the industry,we have found that recycling and remanufacturing is one of the effective ways to solve the above problems;it can not only bring environmental benefits,but also reduce costs for enterprises and bring economic benefits.With the implementation of the new "Management Measures for the Recycling of Scrapped Automobiles",more room for development has been brought about for the recycling and remanufacturing of scrapped automobiles in my country.On this basis,this article will study the selection of recycling modes of each decision-making body in the supply chain.First of all,this article introduces the relevant background,describes the research significance,the current research on channel power and the relationship between OEM and RM at home and abroad,and provides a background basis for the research of the thesis.Secondly,the closed-loop supply chain,game theory and circular economy theory are expounded,which provides a theoretical basis for the following model research in this article.In the following chapters 3 and 4,when the remanufacturer dominates the market and the manufacturer and the remanufacturer form a Nash equilibrium game,a three-level closed-loop supply chain composed of OEM,RM,and R is constructed.The remanufacturer and the manufacturer have reached a cooperation agreement on remanufacturing.The remanufacturer is the only company in the supply chain that has remanufacturing capabilities and supplies remanufactured products to the manufacturer;in the recycling process of waste products,each recycling entity has recycling competition.The main hybrid recovery modes constructed in the two-period model are MR mode,MT mode and RT mode.Through the reverse solution,the optimal decision of each decision subject is obtained under the market advantage of the remanufacturer and the Nash equilibrium game.Through the use of Mathematica software for numerical analysis,the impact of the intensity of recycling competition on the recycling rate,profit of each decision-making body and the total profit of the system is discussed.The research results show that: 1)Regardless of how the intensity of recycling competition changes,it is always negatively correlated with the profit of each decision-making body and the total profit of the system;2)With the remanufacturer occupying the market advantage,the recovery rate of the RT or MT model Higher;the profits of manufacturers and retailers are maximized in the MR model,the profits of the remanufacturers in the MT mode or the RT mode are the largest,and the total profit of the system is the highest in the MR model;3)Under the Nash equilibrium game,RT The total recovery rate of the model is the highest.Manufacturers and retailers have the largest profits in the RT model.At the same time,the total system profits are also the highest in the RT model.The fifth chapter conducts case analysis in the case of Nash equilibrium game to verify the recycling decision of each decision subject in the closed-loop supply chain.This thesis adopts research methods such as comparative analysis,mathematical modeling and simulation.Their use is conducive to studying the decision-making problems of mixed recycling modes under different channel powers from the perspective of mathematical modeling.The quantitative analysis of recycling problems can be more obvious.And the profound conclusions also provide theoretical guidance for the recycling practice of recycling companies.
