供应链体系中VMI服务定价风险及其传导

在生产商向零售商提供供应商管理库存(VMI)服务的条件下,研究在供应链中实施VMI服务定价的风险及其传导问题.首先根据Stackelberg博弈方法得到满足供应链整体利润最大化的最优定价策略,并计算当价格围绕最优价格波动时,风险会如何传导至市场需求和供应链各成员及整体利润.引用经济学中弹性系数的概念及算法,量化定价风险对市场需求的影响程度,以及该风险在整个供应链系统中的传导形式,并给出风险影响程度算式.仿真结果显示,该算式在分析定价风险及其传导时具有实用性和有效性.

VMI service pricing risk and conduction in supply chain system

The issue of service pricing risk and its conduction in the supply chain is studied under the condition that the manufacturer provides vendor management inventory(VMI) service to the retailer.First,the optimal pricing strategy which can maximize the total profit of supply chain is obtained according to the Stackelberg game theory,then the forms of risk conduction that from price to demand and supply chain are analyzed when the price fluctuates around the optimal price.The concept and algorithm of elastic coefficient in economics are used to analyze the pricing risk degree and the way of risk conduction in the supply chain.The formula to calculate the risk degree is also given.Finally,a mathematical example illustrates that the algorithm is practicable and effective in this field.
