In allusion to the traditional case retrieval technology disadvantage of die design, a rough set-based case retrieval method is presented in the die design. To analyze and deal with die case database using rough set theory, and use a method by using grade classification and decision attributes supporting degree to discretize the quantitative features. It confirms the important degree of all types...
A rough set-based case retrieval method was presented in intelligent CAD system of the conceptual design. The case knowledge representation model of the conceptual design based on rough set was brought forward by analyzing features of CAD systems. An approach of reducing the feature attributes and calculating the feature attributes weighting was proposed based on rough set theory. The continuous feature...
