考虑一个工厂，它储备了各种零件，以支持某个客户地区的一组产品的维修。所考虑的问题是确定每个零件的基本库存政策，以最大限度地减少所有零件的预期库存成本，同时满足一些服务约束的总客户完成维修服务。一个启发式的程序开发这个问题的几个变种。启发式是基于对偶理论，并示出了具有密切的联系，以著名的贪婪启发式。令人鼓舞的实验结果所提出的启发式的性能报告。考虑的基本问题结构是类似的工具包问题，但它制定允许应用程序在更广泛的备件物流环境。
Consider a facility that stocks various parts in support of repairs for a set of products in some customer region. The problem considered is to determine base stock policies for each part to minimize expected inventory costs across all parts while satisfying some service constraint on total customer repair services completed. A heuristic procedure is developed for several variants of this problem. The heuristic is based on duality theory and is shown to have a close connection to the well known Greedy Heuristic. Encouraging experimental results on the performance of the proposed heuristic are reported. The basic problem structure considered is similar to the tool-kit problem, but it is formulated to allow applications in much broader spare part logistics contexts.
