【摘要】：随着全球经济一体化的持续发展，市场竞争的日益激烈，汽车零部件制造企业已经进入了微利时代，面临严峻的成本挑战。众多知名的大型汽车零部件制造加工生产企业仅单一注重对原材料的成本控制，在相当长的一段时间内忽视了备件采购的重要性，最终导致了企业备件的采购的管理高成本，库存拥有的备件量远大于维持正常生产运营中所需要的水平，无形中增加了企业的流动资金被过多占用。备件采购管理在20世纪90年代随着供应链理念的出现，以及资本管理不断得到一些跨国企业的关注，从而成为了人们争相开始研究的重要课题。本论文以企业备件管理为背景，针对企业内部备件管理不善和备件库存量高的问题，通过实施ABC分类法、VED分类法以及基于VED的ABC分类法应用，得出了适用于企业的备件分类方法；其次通过移动平均法、一重指数平滑法、二重指数平滑法对企业内部的17款典型备件做需求预测，并且与2012年的实际用量进行比较，得出适合企业的需求预测方法；建立了基本经济补货批量、有限补充能力经济补货批量、补货提前期的处理和离散型需求经济补货批量的备件库存模型，，得出最佳的补货批量和补货间隔周期，并且与原有的库存数量做出对比，计算出减少的库存资金占用量。对于使用量大的备件，通过与供应商协商建立SA（即Schedule Agreement，计划协议），达到零库存的目标。研究探讨现代库存管理手段对降低企业的采购成本、缩短采购周期、降低库存等方面带来的显著效益，为企业今后在运营方面的进一步提升提出实际可行的新思路。
[Abstract]:With the continuous development of global economic integration and the increasingly fierce market competition, automobile parts manufacturing enterprises have entered the era of small profits, facing a severe cost challenge. Many well-known large automobile parts manufacturing and manufacturing enterprises only pay attention to the cost control of raw materials, neglect the importance of spare parts procurement for a long time, and finally lead to the high management cost of enterprise spare parts procurement. The quantity of spare parts in stock is much larger than that needed to maintain normal production and operation. With the emergence of supply chain concept and capital management in 1990s, spare parts procurement management has been paid more and more attention by some multinational enterprises, which has become an important subject that people begin to study. This paper takes the enterprise spare parts management as the background, in view of the enterprise internal spare parts management mismanagement and the spare parts inventory high question, through the implementation ABC classification method Ved classification and based on the VED ABC classification method application, The classification method for spare parts is obtained. Secondly, 17 typical spare parts are predicted by moving average method, single exponential smoothing method and double exponential smoothing method, and compared with the actual consumption in 2012. The demand forecasting method suitable for the enterprise is obtained, and the spare parts inventory model of the basic economic replenishment batch, the limited replenishment capacity, the restocking lead time and the discrete spare parts inventory model are established. The optimal replenishment batch and replenishment interval period are obtained, and compared with the original stock quantity, the reduced stock amount is calculated. For spare parts with high usage, set up Schedule agreements with suppliers to achieve zero inventory. This paper discusses the remarkable benefits brought by modern inventory management in reducing the purchasing cost, shortening the purchasing period and reducing the inventory, and puts forward a new practical and feasible way for the further improvement of the operation of the enterprise in the future.
