【摘要】 “牛鞭效应”对供应链性能和绩效产生了严重的影响。本文基于控制理论建立了多级线性供应链的模型．分别利用噪声带宽和Matlab／Simulink对一个可扩展多主体线性供应链系统的牛鞭效应进行了建模与仿真研究,分析了实施信息共享前后供应链系统的牛鞭效应,探讨了物流延迟时间参数和指数平滑预测参数对牛鞭效应的影响,并给出了减弱牛鞭效应影响的相应策略。更多还原

【Abstract】 The bullwhip effect can have serious impacts on the performance of the supply chain management. In this paper, based on a linear multi - stage supply chain, some simulations have been performed using Matlab/Simu-link. Through methods of noise bandwidth and simulation, comparisons have been made between traditional supply chain and information sharing supply chain, the effect of parameters of the logistics lead times and the exponential smoothing forecast on the bullwhip effect have been analyzed. Finally, some corresponding counter-measures for reducing the bullwhip effect have been brought forward.更多还原
