Knowledge Representation and Object Modeling Based on Design Space for Knowledge-Based Design Support Systems

The improvement of intellectual productivity of the design business is a pressing need of manufacturing. Many general-purposed CAD systems are good to support the works like drawing but not effective to processing and support of design knowledge. Thus, there has been a considerable growth of interest in knowledge-based design support systems. Based on object-oriented methodologies and attribute-oriented modeling paradigms, we have proposed the assembly structure as a design object model and design space for design problem representation. This paper focuses the discussion on the modeling and the knowledge representation about machine elements for knowledge based design support systems. We also verify the effectiveness of the proposed method through the application examples.
