摘　　要：提出将供应商管理库存细分为需求拉动式供应商管理库存和计划推动式供应商管理库存.应用系统动力学方法对传统供应链、需求拉动式供应商管理库存和计划推动式供应商管理库存等三种供应链管理模式进行建模和仿真.放松了一些传统约束,如常见的配送中心无限能力假设,将配送中心不同库存管理方式引入模型.通过仿真,从零售商库存波动变化、长鞭效应减弱程度和供应链总成本多个角度证明了推式供应商管理库存的优越性.证明了除了累积提前期以外,长鞭效应还与信息共享时的库存、生产控制方式有关.VMI（Vendor Management Inventory） is divided into two types：VMI based on push inventory control and VMI based on pull inventory control. The traditional supply chains, push-VMI and pull-VMI are modeled and simulated with system dynamics tools. And some traditional constraints on Dispatch Centers are loosened, such as unlimited capacity, and inventory management methods of Dispatch Centers based on VMI are led into the model. After the simulation,many data including retailer inventory fluctuation diagram, bullwhip insight and the total cost fluctuation diagram are achieved. In terms of these comparable data, the push-VMI outperforms the other two is concluded. And that the stock and manufacture policy also play an important role in deducing the bullwhip besides the accumulative lead time is concluded.
