This paper proposes computerized methods of case-based design aid using similarity and relevance between design cases. First, we introduce methods of describing and recording design cases and design modification cases by physical quantities and their calculations to represent physical phenomena and terms to explain them. Then, we introduce a quantity dimension space (QDS) defined by nine fundamental and supplementary quantities in SI. Similarity between physical quantities is mathematically defined by the average of unit dimension similarity defined in QDS and quantity calculation structure similarity. By using design case similarity in terms of quantities and terms, designers can retrieve and consult the similar or relevant cases to a new design problem. Also, design modification knowledge can be extracted by analyzing past design modification cases. The proposed methods are implemented as a Lisp program and are examined through some example computations.
