摘要
慢速流动备件是企业中普遍存在的备件,和快速流动备件相比,慢速流动备件
往往重要性高、需求量少、价值高、需求难以预测,所以库存控制更加复杂。从某
种意义上说,慢速流动备件库存管理的好坏直接关系到企业能否持续、稳定和协调
地发展。目前国内对慢速流动备件的研究还很少,库存控制方面的研究更少,由于
慢速流动备件自身的特殊性,传统的库存控制方法不适合慢速流动备件,因此对慢
速流动备件的库存控制方法研究具有很强的现实意义。
本论文围绕企业中慢速流动备件库存控制问题,针对传统 ABC 分类法以及多
属性 ABC 分类法的缺点,从备件所属设备出发,提出了考虑设备关键性备件库存
ABC 分类两阶段改进模型。针对慢速流动备件库存控制的难点,在两阶段分类的基
础上,从零件寿命函数角度入手,分析设备系统发生故障概率,通过权衡备件存储
费用和缺货损失成本,给出了总费用最小的库存控制数学模型,并给出具体实例对
模型的有效性进行了验证,结果表明模型能有效的减少慢速流动备件库存控制时间
和库存费用。最后针对慢速流动备件数学模型控制的不足,对慢速流动备件的企业
联合库存管理问题进行了分析,给出了基于 WEB 的库存共享模型。

Abstract
Slow moving spare parts are ubiquitous in manufacturing, in contrast to fast moving
spare parts, slow moving spare parts are usually more critical, more expensive, and more
difficult to forecast, therefore, the inventory control of them are plex. The
performance of inventory control of slow moving spare parts is direct related with the
development pany. At present, there is less research on slow moving spare parts,
especially in inventory control. Owing to the speciality of slow moving spare parts, the
traditional inventory control method is not fit for them, so the research on inventory
control of slow moving spare parts is significant.
Concentrating on the inventory control of continuously producing enterprise’s slow
moving spare parts, the disadvantages of traditional ABC classification and multi-
attribute ABC classification are expounded, an improved ABC classification model
involving equipment criticality is forwarded based on two-stage method. Considering the
difficulty of inventory control of slow moving spare parts, and using the results of
two-stage classification, an inventory model based on life-cycle function is provided. The
optimal reorder point and order quantity can be calculated with the model, and a case is
presented to show the effectiveness of this model. The results indicate that the model is
effective
