【摘要】：库存成本对供应链的成本具有显著的影响，受库存备件的数量、占用资金数量的多少、配送策略等问题的影响，汽车服务备件不同类型的库存控制策略对库存成本的影响差异性较大。随着近几年汽车行业的迅猛发展，汽车企业之间的竞争逐渐地转变为售后服务的竞争，，而良好的售后服务质量依托于完善的备件管理方法。另外，汽车企业为了提高市场占有率，更新换代速度快，如何保证已经停产车型的售后服务质量，满足这些车型的备件需求对汽车行业具有十分现实的意义。 汽车不同生命周期阶段中的备件需求数量存在着显著的差异。本文以一汽-大众公司为例，从库存管理中存在的流动资金占用比例大、库存积压、死库存等问题入手，在成熟期提出了一种区库存之间的横向调拨方法。基于该方法对供应链的库存成本进行了建模，并利用遗传算法和matlab语言实现了模型的求解和运算过程，得出了该模型在库存数量和库存成本方面都优越于传统的方法。在衰退期提出了一种基于回收模式的末次订货模型，通过EXCEL的拟合工具和差分法理论为数据分析工具，该模型以总公司的库存成本为优化目标，最终得到了回收模式下的最优末次订货量和最小订货成本。
[Abstract]:Inventory cost has a significant impact on the cost of the supply chain. It is affected by the quantity of spare parts in stock, the amount of funds occupied, the distribution strategy, and so on. Different inventory control strategies of automobile service spare parts have different effects on inventory cost. With the rapid development of automobile industry in recent years, the competition among automobile enterprises has gradually changed into the after-sales service competition, and the good after-sales service quality depends on the perfect spare parts management method. In addition, in order to improve the market share and upgrade quickly, how to ensure the quality of after-sales service of the stopped models and to meet the demand of spare parts is of great practical significance to the automobile industry. There are significant differences in the number of spare parts in different life cycle stages. This paper takes FAW-VW Company as an example, starting with the problems of large proportion of liquid capital occupation, overstocking and dead inventory in inventory management, puts forward a method of transversal transfer between regional inventory in mature period. Based on this method, the inventory cost of supply chain is modeled, and the process of solving and calculating the model is realized by using genetic algorithm and matlab language. It is concluded that the model is superior to the traditional method in terms of inventory quantity and inventory cost. In the recession period, a final order model based on the recovery model is proposed. The fitting tool of EXCEL and the theory of difference method are used as the data analysis tools. The model takes the inventory cost of the head office as the optimization objective. Finally, the optimal final order quantity and the minimum order cost under the recovery mode are obtained.
