Game Analysis Of Green Supply Chains With Time Delays

In recent years,the global economy is developing steadily and rapidly.With the improvement of people environmental protection consciousness,green supply chain has become the focus of the government,enterprises and scholars.People have a higher requirement for the greenness of products(Product Environmental Protection Degree).The enterprises how to ensure a fair pricing will directly affect the supply and demand of products,further affect the stability of the green supply chain.Green supply chain involves suppliers,manufacturers,retailers and so on.Because the green supply chain may take centralized or decentralized decision-making game,it is very critical to make a comparative study on how to obtain higher profits.Therefore,the profit problem of Competition and Cooperation Game is compared and analyzed.However,due to the impact of research and development costs,the price of green products is often much higher than ordinary products.Therefore,the thesis contrastive analysis the impact of product greenness on supply chain system.And,considering in the field of green supply chain,time delays is not considered into the green supply chain game.However,time delays is a common phenomenon in all kinds of supply chain systems,due to late response to market demand changes.Not only the price,the existence of time delays will also affect the stability of the system.In turn,the performance of the entire supply chain system will deteriorate.Therefore,the thesis analyzes the green supply chain of system stability with time delays and stability performance control.And explore how to reduce the effect.Mainly completed the following three aspects of the work.(1)Based on the comprehensive theory of green supply chain,supply chain competition and cooperation game theory,the development history of green supply chain is analyzed in detail.And it introduced the relevant domestic and foreign research status.On the basis of considering time delays,the thesis analyzes four profit models of green supply chain,which are composed of suppliers,manufacturers and retailers under centralized and decentralized decision-making.Then contrast and analyze their profit situation,so as to find out the optimal profit model.The relevant conclusions have certain reference and guiding value to the construction of strategic cooperative partnership.(2)The thesis analyzes the effect of different green degrees on pricing strategy.The research focuses on the pricing and equilibrium of green supply chain products between green products and ordinary products.The Bertrand Price Game Model is established.And obtains the corresponding price adjustment coefficient variation range through numerical simulation.(3)When a system enters a chaotic state,it becomes changeable and unpredictable,which is the last thing an enterprise wants.Therefore,in this thesis,Chaos Control Method is used to introduce control factors.And different delay parameters are selected to affect the stability of the system and help enterprises to restore the stable state.Then,the significance of chaos control to stable enterprise profit is further analyzed.
