In today's society, an increasingly competitive market, supply chain management as a new management model has been rapid development, has gradually become an effective means for enterprises to improve the overall efficiency, and enhance market competitiveness. But in the concrete implementation of the process, because the information is often not timely, accurate passing, often lead to uncoordinated supply chain operations and the reduction of the level of performance of the supply chain, and information sharing between each node enterprise is important to solve this problem and effective means. Therefore, in-depth research in supply chain information sharing is essential to improve the level of supply chain management performance. \level. Then a simple two-stage supply chain consisting of only a single retailer and a single supplier for the object model, an important indicator for the inventory management of inventory levels and costs mean two metrics, study the market demand is related needs, and to consider retailers and suppliers in order to lead, shared among the members of the supply chain the mean demand information to reduce inventory levels and cost of the supplier. The focus of this study is that traditional inventory information sharing, information sharing three modes supplier inventory levels and costs mean changes in the mode of information sharing and VMI. The study showed that: these three stocks mode, the highest average inventory levels and cost of the supplier information sharing, information sharing traditional mode effectively reduce the the supplier inventory level and cost mean, and information sharing for the implementation of VMI mode reduce inventory levels and supplier costs mean the most significant effect. By sharing demand information with retailers can effectively reduce the average inventory and cost mean, where the implementation of VMI mode of suppliers. Finally, through a specific example, the use of Matlab programming and Excel, image processing analysis of changes in inventory levels and costs for different parameter combinations of three modes suppliers mean, the results show that: With ρ (demand correlation coefficient), σ (degree of demand fluctuations) and lr (retailer's order lead time) increases, more information sharing to reduce inventory levels and supplier costs mean. Including information sharing, VMI mode effect is most prominent. And ρ, σ, lr increase represents increased uncertainty, which explains more members of the supply chain, constitute the more complex, the more unstable the market, the more you want to achieve inter-enterprise information sharing. Therefore, in the vagaries of the supply chain environment in today's society, information sharing is of great significance.
