Behavior based product model as an implementation of the feature approach

This paper introduces a concept and modeling method for intelligent model features in engineering models that can be implemented in industrial CAD/CAM systems. The related research started from earlier results in development of integrated feature based product modeling. An active model is proposed that comprise knowledge from three sources, namely modeling procedures, generic part models and engineers. The paper discusses the scenario of intelligent modeling based engineering. Then key methods for application of computational intelligence in computer model based engineering systems are detailed including knowledge driven models as well as areas of their application. Next, behavior based models with intelligent content involving specifications and knowledge for the design processes are emphasized. Finally, an active modeling, is proposed and possibilities for its application are outlined.
