Reusability of Shoes' Design Information Based on KBE and CBR

A method of reusing and retrieving shoes' design information using CBR (Case Based Reasoning) in area of knowledge based engineering was presented, and a new framework for reusing design information had been created. The framework and CBR inference engine were introduced. And it emphasized the knowledge expression of mold cases by level decomposition tree BNF (Backus Normal Form) description, a method of measure similarity between the design cases and problem requirement by the fuzzy comprehensive evaluation, and the method of reusing and retrieving shoes' design information. This method was validated by the design case of sport shoes in the end. to acquire, express, and utilize knowledge and experience for analysis, decision-making, planning, design and implementation, with a view to solve the problem reasonably in the existing conditions and regulated time. KBE is a research field on the premise of actively using experience knowledge to solve problems, and related to application of artificial intelligence. Research of knowledge engineering is closely related to the computer, and problems are requested to solve by computers. KBE mainly studied knowledge organizations in computer, building high-quality knowledge base, acquiring useful knowledge by computer, and solving the problem using knowledge. Knowledge expression, knowledge acquisition, knowledge utilization constitute the three elements of
