Research on Acquiring Design Knowledge Based on Association Rule

This study presents a method of acquiring product design knowledge. By analyzing the process and mathematics expression of product design, design attributes are taken as item sets and associated relationship among them are taken as analyzing target. Based on the expression and application for domain knowledge, design data are pretreated. Then the correlations knowledge among design attributes is obtained by association rules. A case study is given to illustrate that the method proposed is valid and practicable.
