摘　　要：物流配送已成为电子商务发展中的关键问题之一,也是供应链管理中的核心问题。该文利用仿真软件建立了包括制造商、医药分销中心和零售商的物流配送系统的仿真模型。通过对模型进行仿真可观察物流配送的动态运行情况,从而找到配送过程的瓶颈。在建立的仿真模型基础上及给定的约束条件下,通过构造目标函数对仿真模型进行了优化。通过优化,给出了医药分销中心最优的订购时间间隔和不同药品的最佳库存量,这为实际决策提供了正确依据。Logistics is one of the important problems for Electronic Commerce recently.It is also one of the basic problems of the supply chain management.A simulation model for medicine logistics has been established based on Witness2003in this paper.The model integrates producers,distribution center and retailers as well.The objective of the model is to observe dynamically the running process of the distribution process and to find the bottleneck of the logistics.By establishing objective function,optimization for the model has been processed under given constraints.Through optimization,the right order intervals from producers have been given in the end.The optimal results are the basis of decision making under uncertainty.
