研究了供应链管理环境下新的库存策略·在传统供应链利润模型基础上,对有确定需求、初始库存和允许库存短缺的一种畅销商品,建立了供应商管理库存的供应链模型,并进一步讨论了供应商管理库存下的采购数量和利润,证明了供应商管理库存供应链的最优购买量比传统供应链的最优购买量要高·同时也证明了实施供应商管理库存会使用户的利润增加,而在优化匹配条件或长期激励下,实施供应商管理库存也会使供应商的利润增加,为双方企业合并其库存提供了理论基础·最后以一个数值算例验证了所得结论·

Optimized Purchase Quantity and Profit of Vendor Managed Inventory

For a kind of salable goods in definite demand with good stock which is permissibly, going short for a time, a supply chain model of vendor managed inventory (VMI) is established on the basis of traditional supply chain profit model, with the purchase quantity and profit of VMI discussed as well. The optimized purchase quantity of VMI is proved more than that in the traditional supply chain, and the implementation of VMI is proved that the profit of vendee will increase. On the other hand, the implementation of VMI will enable the vendor to increase profit if providing optimized matching conditions or long-term incentive. As a result, a theoretical foundation is provided for both the vendor and vendee to merge their inventories together. A numerical exemplification is given to verify the conclusion as above.
