Engineering knowledge application in collaborative design

Based on the research of knowledge modeling and the practice of engineering design, the knowledge expression system for knowledge-based cooperative design system was put forward, which includes the engineering language knowledge, the engineering data table knowledge, the engineering instance knowledge and the engineering graphic knowledge. According to the requirement of the collaborative development of enterprise group, using the resources of Chengdu-Deyang-Mianyang networked manufacturing and ASP platform, a knowledge-based cooperative design system has been developed and integrated with ASP platform. A reasoning system based on knowledge expression system has been developed and applied in the cooperative design system. The collaboration among enterprises and knowledge-based design have been implemented. The system has been put into practice in many enterprises.
