Research On The Complexity Of The Closed-Loop Supply Chain Recycling Game Model Based On The Delay Decision

Due to the rapid development of market economy,science and technology continues to improve,coupling with people’s growing demands for personalized products.Manufacturers continue to develop new products to meet the consumer market,resulting in the product life cycle increasingly the shorter,which brought a large number of products to be eliminated early,it not only caused a serious waste of resources,but also did serious harm to the living environment and quality of life.By combining the traditional "reverse logistics" and supply chain,closed-loop supply chain really realize the "resources-products-waste products-remanufactured products" closed loop model of economic growth.This model can be valid for junk recycling manufacturing,improve resource utilization,reduce operating costs,it’s in line with economic development and environmental protection coordinated strategy for sustainable development and has great potential for development,so that it attracts attention of many scholars.Based on the complex dynamics of domestic and foreign scholars study literature review on recycling loop supply chain management and supply chain infrastructure,this article constructs the delayed decision CLSC recycling game model under considering the closed-loop supply chain node enterprise decision-making selection and with application of the theory of repeated games.Then by use of chaotic dynamics theory and complexity theory,the model is derived,and through numerical simulation by use of Matlab software,the complex dynamic recovery game evolution is studied.The main contents and innovations are as follows:1.It extends the research methods of closed-loop supply chain market behavior.In the past,most of the scholars in domestic and foreign research on the recycling management of closed loop supply chain,the operations research and game theory are mostly used method,in order to study coordination and waste materials loop supply chain node enterprises pricing.This article studies the stability of the closed-loop supply chain system through integrated use of a variety of complex theoretical methods of game theory,complexity theory and chaos theory dynamics.2.It constructs two types of recycling game model under considering the delayed decision.In order to be more practical,delay decision is added to the game model of the manufacturer recycling mode and the retailer recycling model.The stability of the equilibrium point of the system is analyzed by using the Jury criterion,and the conditions for the stability of the equilibrium point are also analyzed.Through numerical simulation,it analysis both the recovery mode to adjust the speed of decision variables,delay decisions and the delayed impact of the two parameters of the power system.The study found the decision variables adjusted too fast will cause the system into a state of chaos,the use of delayed decision-making will be delayed chaotic phenomenon,but the delay parameters have different effects on the two recovery modes.3.Since the system which is in a chaotic state,the corporate profits will be significantly decreased,and become volatility,and it will not help the development of closed-loop supply chain.This paper introduces a delay feedback control of chaotic system.The control factor to satisfy the stability condition is obtained by the Jury criterion,and the correctness of the conclusion is verified by numerical simulation.Furthermore,it relates the theories with the practice,the economic significance of chaos control is studied.This chapter provides theoretical and practical guidance for the realization of the stable development of closed loop supply chain system.
