Abstract: During the product evolution design, the two key issues troubled by the designer are design data complex range and design rules difficult extraction. A reduction algorithm based on rough set and an extraction algorithm based on classification consistency rate, are presented. The former completes the product data reduction, the latter achieves the design knowledge mining and rules extraction. Results indicate the effectiveness and high efficiency of the algorithm.
