大型企业多阶段单项采购(MPSSP)模型仿真研究

物流配送系统的复杂性使管理者很难追踪到系统中出现的每一个问题。这些问题可能存在于预测模型、网络优化、库存配额以及物流选址等环节中，对未来的经济效益和运作效率都有着极其重要的影响。因此，在计算机应用日趋广泛的背景下．仿真技术为物流配送系统的优化提供了有效而直接的方式。针对大型企业的特点改进原有的MPSSP模型，对大型企业的配送过程进行仿真。先对实际的物资配送系统进行假设．在符合模型前提的情况下通过MPSSP模型建立三种不同的仿真方案进行比较．并对结果进行统计学分析，获得最优的配送模式。

The Simulation of MPSSP Purchase Model in Large-scale Enterprise

The complexity of logistics distribution makes it difficult for manager to trace every problem exsiting in forecast model,net optimization,inventory quota,location and so on,which has important influence on the future economy benefit and operation efficiency.Therefore,in the background of wide use of computer,simulation puts an effective and direct way for distribution system.Improve already existing MPSSP model according to the characteristics of large-scale enterprise,and carry on simulation to the distribution course of large-scale enterprises.Firstly suppose a provide and distribution system to set up 3 kinds of different artificial schemes through MPSSP model,in order to compare the result of the models.And carry on statistics and analyse the result,then we'll obtain the optimum distribution model.
