Research On The Establishment Of Coordination Mechanism For Supply Chain Of E-commerce Express Service Based On Differential Game Theory

Relying on the rapid development of e-commerce,the express market is expanding rapidly and growing.Express service has become an important link in the process of e-commerce.The quality of express service has become an important factor restricting the development of e-commerce.In view of the decision problem of the different participants in the service chain of ecommerce express service in the face of the quality of express service,the differential game method is used to compare the strategy selection of the service quality of the e-commerce express service.In the game process of express service providers and express service integrators,and in the process of courier enterprises and e-commerce games,the Nash non cooperative game model is set up in turn,the master-slave game model based on the express service integrator,the main slave game model dominated by e-commerce,the cooperative game model and the equilibrium solution are studied.In order to improve the quality of express service and the overall profit optimal value,we analyze the relationship between the result of the theoretical model,the loss of word of mouth and the relationship between the penalty amount and the value of profit by numerical simulation.The results show that,for the different situations of the express enterprises and e-commerce businesses,under certain conditions,the overall profit is gradually improved and it is in line with Pareto's improvement,from non cooperation to master slave to non cooperative game,and the loss of word of mouth will affect the strategy choice of express enterprise and e-commerce,game mode and overall profit.The optimal value.When the two times the difference between the influence coefficient of the word of mouth is greater than the influence coefficient of the express enterprise and the influence coefficient of the e-commerce income,the optimal profit value is optimal when the co decision of the express enterprise and the electric business cooperation is the best,the second is the profit value of the electric business in the dominant position,the lowest profit value is the non cooperation of the express enterprise and the electric business.The game situation of independent decision making.For express service integrators and express service providers,the optimal profit value of express service providers and express service integrators is the best profit value when the express service quality level affects the income function and the calculation of the income share and the expected penalty amount of the express service integrator.The best one is the profit value of the express service provider and the express service integrator in the non cooperative decision making,and the lowest profit value is the game situation that the express service integrator is dominant.Therefore,choosing reasonable game mode and setting up reasonable mechanism can improve the quality of express delivery service.The research conclusion provides a theoretical basis for the cooperation mode of the express service supply chain members under the e-commerce environment to improve the service quality of express delivery.
