【摘要】：经过2008年行业经济危机后,市场规模趋于理性,用户产品的需求越来越不确定和个性化,同时产品的销售价格一降再将,各企业为了保住市场竞争力,都采取降低内部成本的方法来应对行业的变化。在以制造为主的企业中,原材料作为产品需求的基础,占据着30%左右的固定成本,不仅如此,原材料的采购受市场价格波动因素影响,稍有不慎就会增加企业的运营成本。所以适当的原材料库存不但可以作为供应、生产、销售的缓冲区,满足柔性化生产的需要,更主要的是可以降低产品成本增加的风险,因此原材料库存管理通常被作为多数企业控制内部成本的切入点。WD公司拥有制造类企业的所有特征,管理粗放,经验主义优先,原材料成本占据着部分运营成本,同时作为中小企业具有一定的代表性。本文以其实际运营情况为背景,充分描述WD公司当前原材料库存管理的现状,包括原材料的种类、需求预测、采购流程、库存管理方法等。结合WD公司的日常运营分析出原材料库存管理过程中存在的问题,是否存在呆滞料、需求预测和安全库存的设定是否合理,以及采购模式的优化补充等。最后运用科学的库存管理方法,对原材料管理中出现问题提出解决的措施方案,引用历史需求预测法、ABC分类法,定期不定量的订货模式、安全库存的设定等,对现有原材料库存管理方法进行补充优化,使得WD公司的原材料库存管理更加合理、有效。
[Abstract]:After the economic crisis of 2008, the market scale tends to be rational, the demand of user's products becomes more and more uncertain and individualized, at the same time, the sales price of the products will be reduced again and again, in order to maintain the market competitiveness, Both take the approach of reducing internal costs to cope with changes in the industry. In manufacturing enterprises, raw materials as the basis of product demand, accounting for about 30% of the fixed cost, not only, the purchase of raw materials is affected by market price fluctuations, a little inadvertent will increase the operating costs of enterprises. Therefore, proper inventory of raw materials can not only serve as a buffer for supply, production and sales to meet the needs of flexible production, but also reduce the risk of increasing product costs. Therefore, inventory management of raw materials is usually used as the entry point for most enterprises to control internal costs. WD has all the characteristics of manufacturing enterprises, management is extensive, empiricism is preferred, raw material costs account for part of the operating costs. At the same time, as a small and medium-sized representative. Based on the actual operation of WD Company, this paper fully describes the current situation of raw material inventory management, including the types of raw materials, demand forecasting, procurement process, inventory management methods and so on. Combined with the daily operation of WD Company, the problems in the process of raw material inventory management, whether there are stagnant materials, whether the demand forecast and safety inventory setting are reasonable, and how to optimize the purchasing mode are analyzed. Finally, by using the scientific inventory management method, the paper puts forward some measures to solve the problems in raw material management, including historical demand forecasting method, ABC classification, regular and unquantitative ordering mode, safe stock setting, etc. The existing raw material inventory management methods are supplemented and optimized to make the raw material inventory management of WD more reasonable and effective.
