Problems of Quantitative Models in Large Management Information Systems: A Comment

In a recent article, Rosenman [Rosenman, B. B. 1980. Problems of quantitative models in large management information systems. Interfaces10 (2, April) 102–105.] describes and arborescent inventory system where each stage or level obtains its parts from a uniques immediate predecessor and distributes these parts to a unique set of immediate successors. Various approaches have been proposed for determining optimal and near-optimal single cycle policies for deterministic arborescent systems for a single product. Because of complexity, the use of these approaches for large scale problems proved to be inappropriate. Some alternative approaches are also considered.
