Research On The Model Of Evolutionary Game Of Dual-channel Supply Chain Considering Multiple Participant Behavior

With the rapidly development of E-commerce,selling products through multi-channel in supply chain become more and more common.In the dual-channel supply chain,there are both horizontal channel’s conflict and vertical members’ conflict in the competition.In addition,the decision-maker’s behavior,consumer’s behavior and so on will also have a variety of effects on the supply chain.Based on these questions,we established a price game model of dual-channel supply chain on economic theory and chaotic dynamics theory.Simulation shows the complex behavior of the long-term price game model.It is a realistic guide for the supply chain managers of dual-channel.The main innovative points and findings are as follows:1.This dissertation established a model of price games in dual channel supply chain market based on nonlinear dynamic theory.The different competitive conditions in reality are considered in the model.Prove the instability of boundary equilibrium of dynamic game.The different ways of the system entering into chaos are analyzed by parameter basin plots.The result shows that the higher adjustment speed will make the system enter into chaos through the period doubling bifurcation or N-S bifurcation.We also measure performances of chaotic properties of the model by using the indexes such as Lyapunov exponent and the chaotic attractors.The effect of chaos on the pricing and profit of the system is analyzed.In addition,when the system enters into chaos,different control methods are studied.It will make the research about dual-channel supply chain richer and have guidance to practice.2.This paper study different ways of game between manufacturer and retailer.We established Stackelberg game model led by manufacturer and retailer respectively,and we also discussed the model of Nash game.We present a comparative analysis between the different models.Thesis proves the existence of the solution of Stackelberg game and Nash game and the analytical solution is given.The results show that it is advantageous for the leader of the game when the system on the stable region.Once the system leave stability domain,the followers will have more profits.3.The paper researches a dual-channel supply chain considering Participants behavior.We propose two different pricing policies in supply chain with a fair caring retailer;we consider a model which the retailer has the option of introducing a store-brand(SB)product to compete with the manufacturer’s national-brand(NB)product;we also research a closed loop supply chain with reference price effect.Results show that the participants’ behavior will affect the system stability domain.With the increase of the adjustment speed and the sensitivity coefficient,the stability of the system region will be reduced.The retailer’s fairness concern is advantageous for himself but the excessive fairness concern is not always benefit to the retailer;it can also reduce the retailer’s profit.Retailer’s proprietary sales behavior results in low direct price and low retail price,it is benefit to consumers.This competition will increase the system stability domain and bring more profits for retailer themselves,thereby reducing the impact of the manufacturers set up direct sales channels.In the model of the dual-channel closed loop supply chain with reference price effect: manufacturer recycle behavior can increase the profit of the supply chain.In the stable region,the profit of the retailer will increase with the increase of the reference price coefficient,while in the intense stage of the game,the market price will fluctuate violently,and the profit of the game leader will be decreased with the increase of the reference price coefficient.
