RFBS: A model for knowledge representation of conceptual design

Conceptual design has been broken down into sub-processes and elementary tasks in methodologies. These methodologies proposed suggest their systematic application. This paper assumes the possible execution of these tasks automatically. Nevertheless, it is necessary for computers to integrate the knowledge required during the conceptual design process. Knowledge models have been proposed, for instance Gero's Function-Behaviour-Structure (FBS) model for design. This paper presents the integration of methodologies with a model of knowledge for conceptual design in accordance with model-driven engineering. Our proposition extends the FBS model and presents its practical implementation through ontology and language such as SysML. (C) 2010 CIRP.
