| With the development of economics and the diversification of the products, the market demand presents the strong uncertainty. This is a challenge for the enterprise supply efficiency. As a new pattern of inventory management, Vendor Managed Inventory ( VMI ) can effectively eliminate the" bullwhip effect in supply chain", in order to improve the entire supply chain overall performance. For the suppliers and retailers, the expected revenue will increase in the long term. However, the distribution of the revenue is unfair because of the transfer of the inventory management responsibility. In this case, the retailers enjoy the most benefits of VMI, while the suppliers, bearing the cost of stock and stock risk, have received only a small part. This proceeds contrast brings the negative factor to the close cooperation of the enterprises in supply chain. Therefore, in order to share the cost of stock and inventory risk, it is necessary to study the reasonable coordination mechanism of supply chain profit allocation. Based on the above background, this article studies establishing a reasonable quantity discount model to coordinate the VMI supply chain.First of all, this paper expounds the theory of VMI, including needs analysis, inventory management, supply chain management and price discount mechanism; Then, considering addition type demand, shortage penalty and excess charge, this paper analyzes the VMI "double marginalization effect" phenomenon on the lack of revenue coordination mechanism. This result indicates the necessity of revenue coordination mechanism. Further, based on the above assumptions, this paper studies the rationality of using the quantity discount to solve VMI revenue coordination problem, and seeks out the quantity discount form which perfectly coordinate the VMI supply chain. Finally, this paper uses the numerical analysis method to verify this conclusion. The research has enriched the content of VMI revenue coordination mechanism, and eliminates the adverse factors which influence of the implementation of VMI. The calculation result provides a theoretical basis for the enterprises on wholesale price, retail price and order quantity decision, and has the important theoretical and practical value. |
