【摘要】：国内电子消费市场的竞争越来越激烈,利润空间越来越小,成本控制及服务差异化战略显得尤为重要。维修备件对于产品的整体成本和利润有直接的影响,也是公司服务品质提升的重要保障因素。库存管理是控制维修备件成本的重要途径。本文以MJ公司为研究背景,重点研究MJ公司维修备件库存管理存在的问题,并提出相应的解决方案。修理级别是维修备件库存管理的立足点和出发点,通过修理级别对备件库存的影响进行分析,在给定服务水平的前提下选择恰当的修理级别以及库存控制方案。备件需求预测是维修备件库存管理的重要部分,针对MJ公司的现状,提出使用故障率计算法以及加权移动平均法对备件需求预测方法进行改善。重点运用基于层次分析法的ABC分类方法加强对维修备件的分类管理,将维修备件以经济性、易得性、关键性作为分类准则,通过实例数据进行分析计算,并针对分类结果给出相应库存管理策略。MJ公司修理级别的优化有利于在确定维修服务水平的前提下降低维修总成本,有利于选择合理的库存控制方法。MJ公司通过基于层次分析法的ABC分类方法的优化,有利于库存管理改善的主要方面为:备件库存结构的优化,备件库存水平的下降,备件缺货率的降低,备件库存人员工作效率的提升等。
[Abstract]:The competition of domestic electronic consumption market is more and more intense, the profit space is smaller and smaller, the strategy of cost control and service differentiation is particularly important. The maintenance spare parts have direct influence on the overall cost and profit of the product. Inventory management is an important way to control the cost of maintenance spare parts. Taking MJ Company as the research background, this paper focuses on the problems existing in the inventory management of maintenance spare parts in MJ Company. The corresponding solutions are put forward. The repair level is the foothold and starting point of the maintenance spare parts inventory management, and the impact of the spare parts inventory is analyzed through the repair level. Choosing the appropriate repair level and inventory control plan under the premise of given service level. Spare parts demand prediction is an important part of maintenance spare parts inventory management, aiming at the current situation of MJ Company, The method of calculating failure rate and the method of weighted moving average are put forward to improve the forecasting method of spare parts demand. The ABC classification method based on analytic hierarchy process (AHP) is used to strengthen the classification and management of spare parts, which is economical and easy to obtain. As the classification criterion, the key is analyzed and calculated by the example data, and the corresponding inventory management strategy is given according to the classification result. The optimization of the repair level of MJ Company is beneficial to reduce the total maintenance cost under the premise of determining the maintenance service level. The optimization of ABC classification method based on Analytic hierarchy process (AHP) is beneficial to the improvement of inventory management in the following aspects: the optimization of spare parts inventory structure, the decrease of spare parts inventory level, Spare parts shortage rate reduction, spare parts inventory staff efficiency and so on.
