Dynamic Game Research And Application On Supply Chain With Cold Transportation Under Practical Contracts

With the continuous development of the economy,people are increasingly demanding the quality of products such as food and medicine,which sets new requirements for the development of the cold-shipped supply chain.Cold supply chain in the production,processing and transportation sectors may occur loss and deterioration.Rely on the traditional logistics mode of operation for product transport,more and more shows the problem of high product loss rate.First of all,from a market perspective,the development of cold chain more in line with people's expectations of higher life needs.And then from the business point of view,the management of cold-chain products,not only for enterprises to save a lot of direct costs,and improve business Brand value.Finally,from a social point of view,the development of cold chain can also enhance the utilization of the entire social resources and create more social value.The cold chain takes the enterprise as the main body to carry out the cold delivery service as the core in the process of the cold delivery.Therefore,there exists a rich system game behavior in the market.This paper builds a dynamic Stackelberg game model of cold supply chain based on a variety of practical contracts in the context of new demands of consumers and takes a single manufacturer and two downstream retailers in the cold chain supply chain as research Object,conducted a model and applied research.This paper introduces the influence of manufacturers' efforts on cold-working to the market demand,and studies discrete-time dynamic system models including dynamic price-game and effort-driven dynamic decision-making.Among them,the manufacturer responsible for the production of products,and two retailers refrigerated transport distribution;two retailers are responsible for product sales.Two retailers first make their own retail price decisions;manufacturers observe the two retailers price information,and then make their own decision-making variables.This paper studies the linear relationship between the effort level of cold transport and the market demand.The Nash equilibrium solution for all decision variables in the cold chain dynamic game model is given.The influence of parameters on the stability of power system and corporate profits is studied.The impact of the actual contract on the cold chain game is discussed;the complex system kinetic characteristics of the system when the system enters the bifurcation domain or the chaos domain are discussed;and the numerical simulation is given by using the computer software.The results of the study demonstrate that the contract will affect manufacturers 'pricing behavior and cold-working efforts,and eventually change the retailers' pricing of their products.In addition,the results of this study show that the change of the adjustment speed of manufacturers and retailers' own decision variables may affect all members of entropy of cold-shipped supply chain,and even affect the stability of the system.Finally,based on the delay feedback control method in the control theory,this paper regulates and controls the system from chaos state to the stable state.The results of this paper provide some theoretical basis for the development of cold chain in the new context,and have strong practical significance.
