基于系统动力学的配送中心仓储系统研究

Research on Warehousing System at Distribution Center by System Dynamics

配送中心仓储系统的优化目标是使库存量尽量小而又能保证不会缺货。本文选用系统动力学方法对配送中心仓储系统进行深入分析,在进行系统边界分析与系统因果关系分析后,建立起配送中心面向三店铺配送的系统动力学流图与方程体系,并结合实例进行计算机仿真模拟。最后得出配送中心优化方向的相关结论——提高需求预测的准确性、减少供货延迟时间、增加库存调节时间及加强信息沟通机制。

The optimization goal of a distribution center is to meet the demands at lowest inventory. Based on the methodologies of System Dynamics, the paper carries out an in-depth analysis over the warehousing system of a distribution center that caters to 3 stores with dynamic flow chart and formula system. The modeling and computer simulation of the real cases are also given. It is concluded that, to achieve the desired optimization of distribution centers, the enhanced forecasting accuracy, minimal distribution latency, increased inventory adjustment time and the better information communications mechanism are all essential.
