The Multi-Item Setup-Reduction Investment-Allocation Problem with Continuous Investment-Cost Functions
分析多产品系统中减少设置时间的投资优先级，提出目标函数变换方法，并指出管理者不应按顺序将每个产品的设置减少到最优，这与现有文献建议不同。
In this note, we analyze investment priorities for setup-reduction programs in a multi-product system. We provide an objective function transformation for the model developed by Porteus (Porteus, E. L. 1985. Investing in reduced setups in the EOQ model. Management Sci. 31(8, August) 998–1010.) that permits the use of marginal analysis in both the single- and multiple-item problems. For the multiple-item problem, we show that managers should not reduce the setup for each product to its optimum in sequential order. This is in contrast to recommendations found in the existing literature.
