| Abstract: | Knowledge acquisition in computer aided fixture design (CAFD) is essentially a problem of pattern classification and recognition.Based on the rough set theory and the features of fixture design,a knowledge acquisition model of CAFD is proposed. In light of case design data,the knowledge database of fixture design export system is built with the application of reduction of deci- sion table in the rough set theory.The knowledge database is maintained dynamically with the help of the inference engine and syn- thesis database. |
