A decision support system for the management of a production organization must include an explicit model or models of the production system. When the organization faces a dynamic environment, dynamic models are most appropriate. The document presents dynamic models of production at two levels of details. First, it extends existing activity analysis models for detailed networks to include the common situation of significant, finite processing times at each activity. This extension shows that dynamic activity analysis models require different indexing functions for the application of labor and machine services and for the application of raw materials and intermediate products. It is demonstrated that the improved accuracy of this model is very significant when the typical processing time in the system exceeds the planning time-grid intervals. The importance of this development is in the identification of the underlying assumptions and range of appropriateness of the existing models and in the extension of these models to non-instantaneous production processes.
