Abstract : The 'Integrated Computer Aided Manufacturing - Definition' (IDEF) methodology, developed by the U.S. Air Force to analyze manufacturing, lacks a mechanism for direct evaluation of system performance. Prototype software entitled 'IDEF/System Dynamics' was developed which allows a user to define a manufacturing system as an IDEFO model and automatically generate a simulation model of the system. After the user adds time durations of events and the initial state of the system, the simulation model can be run. The prototype software demonstrates the feasibility of the overall approach including the necessary algorithms and database interaction. The 'IDEF/System Dynamics approach to manufacturing system design can be used for either a 'greenfield' project or to modernize the current operations of an existing plant. In order to reach a commercial software user audience, it will be necessary to enhance the prototype to allow models to be entered graphically (presently the model is entered in tabular form) and to add more controller functions such as counters, timers and data manipulation elements.
