Abstract:The concept of the knowledge-based engineering (KBE) was annotated. The advancement of the KBE system was discussed. The shoe last structure design system based on KBE was developed by u- sing knowledge fusion (KF) on software Unigraphics. The knowledge base was built with the fuzzy inference strategy. The processes of computer aided conceptual design and functional structures of its sub-application systems were studied by the technology such as KBE, virtual design, and etc. With the tool design system of shoe last as example, the model was generated automatically in KF system. The rapid design was achieved by convenient fuzzy modification and by combining fuzzy inference and KF together. The system provides a practical approach to shorten product life cycle and preserve design experience and knowledge.
