The Coordination Of I Automobile Enterprise Distribution System In Supply Chain With Supply Chain Contract

With the rapid development of automobile industry,automobile's production and sales has ranked first in the world for eight consecutive years.Automobile industry as a national strategic and pillar industry,is a key area of steady growth,expanding demand.Distribution is an important part of automobile marketing,and it is the key link between manufacturing enterprises and consumers,thus,auto distribution supply chain coordination problem has very important influence in the development of automobile industry.As the starting point,this paper depicts the disharmony situation in this supply chain,deeply analyzes the characteristics and the present situation of the distribution supply chain,and summarizes conflicts in sales incentive strategy and profit distribution in I automobile distribution supply chain,finally proposes the new supply chain coordination scheme.This scheme changes the original sales incentive strategy.Firstly considering the retailer sales effort level's effects on customer requirements,and then based on the supply and demand relations between the distributor and retailer,this paper abstracts I auto enterprise and retailer's profit function,which is the expansion of the traditional newsboy model.In order to be more suitable for I auto distribution supply chain coordination model,the quantity flexibility contract and revenue sharing contract have been introduced.Using Stackelberg game theory model,the leader is the supplier,and the follower is the retailer.In the proposed model,the necessary condition is developed to achieve the perfect coordination.To be more practicable,select one class of the car's model as the initial value of the parameters in the model.Using MATLAB to solve it,verify the quantity flexibility contract and revenue sharing contract that are both feasible to coordination I auto distribution supply chain.In the view of result,compared with the original model,the new supply chain coordination scheme realizes pareto improvement,and its validity is also proved.When the contract parameters satisfy certain conditions,the retailers and I auto enterprise both can be encouraged.Thus the new coordination scheme solves the conflict of I auto distribution supply chain,at the same time,the distribution supply chain has the optimal coordination solution.What's more,in order to know how the external environment changes influence the model,the sensitivity analysis is also given.When the retail price,purchase price,inventory cost,shortage cost,the sensitivity of sales efforts and sales effort cost coefficient changes,how the effect on the retailer's order quantity,sales effort level and the profit of the retailer,I auto enterprise and the whole distribution supply chain.The result is also of great significance for other automobile enterprise that want to use supply chain contracts to realize coordination,and it also provides new ideas for those have performed supply chain contracts but not have good effects.
