Abstract

This paper proposes a rough set based approach to early design analysis. The approach aims at providing a metrics to facilitate the evaluation of design concepts and enable early detection of inadequacy in design. Based on the rough set theory, an information system can be constructed using information such as design concepts and design capabilities gleaned from past designs. This information is then used to derive a set of design rules for the analysis of new design concepts. The proposed approach embodies a novel technique for the handling of unavailable information, which is a frequent occurrence in product design. The details of the approach, ...
