Hierarchical planning systems support medium range planning decisions in a batch processing production environment. In this approach, higher level tactical decisions impose constraints on lower level operational actions. Several heuristic approaches to hierarchical production planning have been proposed in the management science literature. This paper compares, conceptually and empirically, four of these approaches. The paper begins by discussing the direct optimization approach, and its associated drawbacks. The second section briefly describes several approaches to the design of a hierarchical production planning system and the distinguishing characteristics of the resulting algorithms. The third section compares four different methodologies for disaggregating tactical plans in a hierarchical setting. The paper concludes with recommendations for specific approaches to disaggregation in differing production environments.
