【摘要】 ERP系统是20世纪90年代初在国外兴起的最先进的企业管理技术和方法,能为企业带来巨大的收益。本文以ERP系统中的库存管理为研究对象,对其库存控制模型进行了研究。通过介绍ERP系统的发展、库存管理的作用,指出ERP库存控制模型的研究具有现实指导意义。在此基础上,结合实例,对已有的库存控制方法进行了改进,获得了较好的库存模型,减少了库存量,降低了库存资金,从而增加了企业的经济效益。主要研究内容为:一、建立需求是连续稳定的库存控制模型。基于传统的EOQ模型,考虑相关需求和有限的缺货风险,采用数理统计的方法,提出服从正态分布的连续稳定需求的ERP库存模型,分别确定在安全库存可以被消耗和不可以被消耗两种情况下合理的订货点、订购批量、订购时间。并利用实例证明所建模型的合理性;二、建立需求是离散随机变量的库存控制模型。对传统的报童问题进行演化,考虑了原材料的转化率和产品的耗费成本,提出需求是离散不稳定的ERP库存控制模型,依据模型确定合理的产量和安全库存量,并通过对比JIT方法,利用实例证明所建模型的合理性。最后,提出合理的绩效评价方法对所建模型进行有效的绩效管理。通过上述研究,试图给企业库存相关的决策活动提供适当的帮助与借鉴。更多还原

【Abstract】 Enterprise Resource Plan - ERP is the most advanced technic and method about enterprise management at the beginning of the 1990s on abroad. It has tremendous benefits to enterprise. In this paper, the inventory model of ERP has been singled out to be the studying target.First, the development of ERP and the impact of inventory management have been introduced. Then the realistic value of ERP inventory model has been concentrated on. Based on that, with examples, optimizing inventory, getting better inventory model, reducing the inventory quantity and lowering inventory funds. So it is good to enterprise economic. The main researches contain two parts. Firstly, building the inventory control model about continuous stable requirement. Considering the relevant requirements and a certain extent risk out of stock on the traditional EOQ model, then adopting statistical methods, at last, advancing the ERP inventory model which subjects to the Normal. Besides it, on the basis of this model, determining the safety stock which can be consumed and not, reasonable point of order, quantity of order and time of order, Secondly, building the inventory control model about discrete random variable requirement. Evolution the traditional Newsboy, taking into the conversion of raw materials and products costs, then advancing the ERP inventory model which subjects to discrete random variable requirement, on the basis of this model, determining the right production and safety stock. What’s more, prove it’s right by comparing JIT method. Finally, put forword right performance management for the two models.Hope to give some advice to enterprises when it decides the inventory.更多还原
