Research Of Contract And Game Model Of Electricity Supply Chain Considering Commodity Quality

Emerging pure electric business mode,is a kind of use of the Internet technology based on a third party.Whether based on PC computer or mobile phone,consumers can easily shopping quickly,save a lot of time for consumers.But because the network shopping,the consumer only relying on the introduction of images to buy goods on the web,real quality of the product is in the dark,so that many consumers receive the goods later found that the actual product is far away from the website description,led to the current network shopping return phenomenon is obvious.In this paper,based on the studied background of e-commerce supply chain,this article will combine the requirement of online commodity quality of consumers with the degree of efforts to improve the quality of the goods of producers,and through game theory,contract theory,analyze the game action between supply chain members and study of the supply chain coordination problem,the main work is as follows:First of all,easy for two level supply chain composed of a single electrical traders and manufacturers produce high quality product supply chain contract,taking into account the degree of manufacturers improve product quality to this factor,and assumes that the market demand is only affected by commodity prices and product quality,set up game model under the decentralized state with producers and based on revenue sharing and cost sharing contract to the perfect coordination of supply chain,and an example is given to verify this model.Then,it consists of a single electrical traders and manufacturers of contract to product the high quality product of two level supply chain,considering the degree of effort for the manufacturers to improve product quality and the utility factor of consumers for high quality goods,establish the corresponding market demand function,and using the theory of mean-variance to add the electricity’degree of risk aversion to the model,set up game model under the decentralized state with producers,then based on the "revenue sharing and cost sharing" contracts,and assumes that share proportion and the cost sharing proportion is same to coordinate electricity supply chain,use case analysis verify the model.
