建立了电子市场环境下双源渠道的库存控制模型·该模型包括Internet渠道和传统渠道两个方面的动态控制过程,其中库存水平是状态变量,生产量和供应量是控制变量·定量描述了电子市场双源渠道的牛鞭效应,分析了牛鞭效应的控制机理,应用控制理论提出了需求最坏扰动情况下牛鞭效应的H∞控制算法·最后,结合上海宝钢益昌公司电子商务的实际情况进行了仿真计算,分析了该公司双源渠道的牛鞭效应,验证了H∞控制算法对电子市场双源渠道牛鞭效应的抑制作用

Dual-Channel Model on E-Market and H∞ Control Strategies for Its Bullwhip Effect

An inventory control model of the dual-channel on e-market is developed including the dynamic controlling process for both Internet and traditional channels, where the inventory level is a state variable and the product output and supply are controlling variables. Describing quantitatively the bullwhip effect of the dual-channel and analyzing its control mechanism, an H∞ control strategy is proposed according to control theories to control the bullwhip effect when the demand's disturbance is worst. Combining with the practices of e-business in Shanghai Baosteel Yichang Co., a simulating calculation is done to analyze the bullwhip effect, which verifies the controlling effect of H∞ control algorithm for the dual-channelon e-market.
