The invention is a design evaluation apparatus for evaluating a design composed of a plurality of design elements. The apparatus has a database stored therein. The database contains design elements, evaluation terms and a table defining relations of the respective design elements with respect to each of the evaluation terms. At least one of the evaluation terms representative of the design is selected from the table, based upon the design elements of the design. The selected evaluation term is used to produce an evaluation result.

Apparatus for selecting and evaluating design based on stored information

A system for designing a configuration capable of accounting for subtle variations of each design element involved. In this system, evaluation terms which expresses impressions associated with the design elements of the configuration is entered; a fuzzy knowledge data-base for memorizing relationships between the evaluation terms and the design elements in terms of fuzzy sets represented by membership functions is prepared; a pattern of each design element appropriate for the evaluation terms entered at the entering step is inferred according to the fuzzy knowledge data-base, and the configuration is constructed from the inferred pattern of each design element; and the constructed configuration is outputted.
