Research On Decision Optimization Of Automakers Considering The Influence Of Supply And Demand Under Dual-credit Policy

In this paper,the production decision optimization of multi-automakers are built under dual-credit policy.Next,considering dual-credit policy,epidemic subsidies of supply side,and consumer preference of demand side,three production decision optimization models of automakers are established.In the end,the production decision optimizations are made during different decision backgrounds.This paper first analyzes the production decision optimization of automaker under dual-credit policy.Then the decision-making model of automaker are built under the independent decision mode and cooperative decision mode.The goals of automaker are different in the two modes.The results show that the regulation of integral quantity of fuel vehicles and new energy vehicles is important to the diffusion of new energy vehicles.Secondly,under the dual-credit policy and epidemic subsidies of supply side,this part develops a production decision optimization model.Aiming at two automakers that sell fuel vehicles and new energy vehicles respectively,the profit models are built.Then we solve and analyze two models under static and dynamic conditions.The results show dual-credit policy and epidemic subsidies have a synergistic effect;Under the background of the epidemic,new energy vehicles have gained a market advantage which has a certain timeliness,and this advantage will be reduced with the epidemic situation.Finally,we study the influences of dual-credit policy and consumer preference of demand side to the production decision optimization of aotumaker.Aiming at a automaker which produces both fuel vehicles and new energy vehicles,we build a utility function which considers consumer preference factors such as anxiety tolerance.Then we solve and analyze the model from the view of points price,points ratio,and consumer preference on the demand side.The results show the anxiety tolerance factors related to the driving range and charging pile coverage rate of new energy vehicle consumers on the demand side,as well as the inhibition stimulation of restriction number and travel restriction of fuel vehicles,have a obvious influence on the diffusion of new energy vehicles.
