【摘要】：企业经营生产必须有库存，但库存又会导致资金积压、场地占用、折旧损耗等浪费，从而推高商品的成本。本课题以一家中型的电子产品制造企业——NEO公司为研究对象，把库存控制的理论运用到实际中，以实现企业的生产物料库存管理的改善。本文的第一章引述了库存控制的理论与方法，研究了较多的库存管理的文献资料。第二章对NEO公司的库存管理现状进行了深入的分析，找出了公司原材料库存管理中的主要问题及原因，主要是有库存水平较高、呆滞物料比例偏大、以及冗余采购与过量生产的浪费等。第三章根据所分析出来的问题及原因提出了改善的方法，主要有：运用ABC分类法对物料进行分类；运用“确定型需求”的控制模型对公司用量最大的一类物料进行控制，，调整A类物料中的通用材料的安全库存，引入预测技术减少A类专用物料的存货量，降低库存水平；制定呆料处理流程，及时回收资金；从SAP系统切换到了易飞ERP系统，推进JIT生产，减少因订单变更、产品改版而造成的浪费。经过近一年的研究与实践，NEO公司的原材料库存有了明显改善。本文最后一章进行了改善效果分析：原材料库存周转率提高了13.9%，呆滞半年以上的物料减少了30.3%，库存成本下降，订单的准时交货率提高。本课题的研究结论是：中小型电子制造企业，虽然物料种类繁多、生产周期长，控制的难度比较大，但引入库存控制理论、加强对数据的分析应用、推进JIT生产、选择合适的ERP系统，是可以有效地改善库存管理状况的。

[Abstract]:There must be inventory in the operation and production of enterprises, but inventory will lead to the waste of funds, site occupation, depreciation and so on, thus driving up the cost of goods. In this paper, NEO Company, a medium-sized electronic product manufacturing enterprise, is taken as the research object, and the theory of inventory control is applied to practice in order to improve the inventory management of production materials. The first chapter of this paper cites the theory and method of inventory control, and studies more literature on inventory management. In the second chapter, the present situation of inventory management in NEO Company is deeply analyzed, and the main problems and causes in the inventory management of raw materials are found out, such as the high inventory level, the large proportion of stagnant materials, the waste of redundant procurement and excessive production, and so on. In the third chapter, according to the problems and causes analyzed, the improvement methods are put forward, which are as follows: using ABC classification to classify materials, using the control model of "definite demand" to control the class of materials with the largest consumption of the company, adjusting the safe inventory of general materials in class A materials, introducing prediction technology to reduce the storage volume of class A special materials and reducing the inventory level; Make the processing process of dull materials, recover the funds in time; switch from SAP system to flying ERP system, promote JIT production, reduce the waste caused by order change and product revision. After nearly a year of research and practice, NEO raw material inventory has been significantly improved. In the last chapter of this paper, the improvement effect is analyzed: the turnover rate of raw material inventory is increased by 13.9%, the material with lag for more than half a year is reduced by 30.3%, the inventory cost is reduced, and the punctual delivery rate of order is increased. The conclusion of this paper is that although there are many kinds of materials, long production cycle and difficult control in small and medium-sized electronic manufacturing enterprises, the introduction of inventory control theory, strengthening the analysis and application of data, promoting JIT production and selecting appropriate ERP system can effectively improve the inventory management situation.
