ABC存货分类在实践中被广泛使用，需求量和需求量是最常见的排名标准。ABC应用程序中的标准方法是为类中的所有库存单位(SKU)设置相同的服务级别。在本文中，我们(对于三个大型现实生活数据集)表明，同时应用需求值和需求量作为ABC排名标准，并且每个类别具有固定的服务水平，导致解决方案远远不是成本最优的。张等人提出的另一种判据。性能要好得多，但与本文提出的新准则相比仍有相当大的差距。新的标准也更加通用，因为它可以考虑SKU的关键程度。管理洞察力是关于哪一级应该具有最高/最低服务级别的，这是一个在文献中一直存在争议的话题。
ABC inventory classifications are widely used in practice, with demand value and demand volume as the most common ranking criteria. The standard approach in ABC applications is to set the same service level for all stock keeping units (SKUs) in a class. In this paper, we show (for three large real life datasets) that the application of both demand value and demand volume as ABC ranking criteria, with fixed service levels per class, leads to solutions that are far from cost optimal. An alternative criterion proposed by Zhang et al. performs much better, but is still considerably outperformed by a new criterion proposed in this paper. The new criterion is also more general in that it can take criticality of SKUs into account. Managerial insights are obtained into what class should have the highest/lowest service level, a topic that has been disputed in the literature.
