Constrained Forecasting: Some Implementation Guidelines
研究了约束预测系统中产品组大小和分组标准两个参数，通过康明斯发动机公司的产品数据与传统预测方法对比测试，为系统实施提供指导。
ABSTRACT Constrained forecasting has become a popular approach to the complex task of predicting future sales. Mixed performance results have been obtained by companies employing constrained forecasting systems software packages which probably reflects the lack of any clear system implementation guidelines. A number of important operational parameters such as the number of product families, criterion used to define product families, number of system levels, etc. must be specified. This study reports on an investigation of two of these parameters: product group size and appropriate grouping criterion. Different tests are performed with the constrained forecasting system and compared to a traditional forecasting approach using product data from the Cummins Engine Company of Columbus, Indiana.
