Improved implementation of inventory control models through equivalent formulations
展示了一个发展中国家多品种定期盘点库存控制的实际案例，发现两种不同复杂度的模型公式在最优解上等价，从而为简化实施提供了工具。
Abstract This paper summarizes an actual multi‐item periodic‐review inventory control study conducted in a developing country. The firms of developing countries are usually less fortunate than their counterparts in industrialized countries in terms of management information systems, personnel and other infrastructure to successfully implement the results of research studies. Therefore, the management scientists of these countries are more obliged to formulate managerial problems in such a way that “decision‐framing” models thus developed require the least estimating and updating efforts possible, yet not sacrifice much from the optimal solution which otherwise could have been obtained. In this study, two formulations of an actualinventory control problem, one much easier and less costly to implement than the other, are shown to be equivalent with respect to the optimal solution. This result offers an instrument for implementation improvements in inventory control systems.
