基于存货促销的供应链协调问题的研究

讨论了零售阶段需求依赖于货架展示量的供应链的协调问题，特别地，由于货架空间的稀缺，零售商的存货持有成本假设为非线性的成本函数。在一个零售商的情况下，给出了决策变量及供应链利润分配的显式解。当存在两个相同的零售商竞争时，给定市场份额按比例分配原则．证明此时存在唯一对称的Nash均衡解，供应商可以用相同的合同协调供应链。最后通过数值算例说明所得结果。

The Study on the Supply Chain Coordination when Inventories Stimulate Demand

The supply chain coordinating contract was discussed for retailers having demand rates that increase with shelf space; specifically the shelf space cost is a non-linear function that is more realistic for most retailing situations. For one single retailer, the explicit solution of the decision variables and the proportion of the channel profit allocated to the retailer were presented. When two homogeneous retailers compete in that product's market, given the proportional allocation rule, Nash equilibrium in this model was found; also the supplier can use the same contract to coordinate the supply chain. Finally the results were analyzed by conducting numerical examples.
