This paper deals with an interactive system which is able to select mechanisms of mechanical systems in conceptual designs. In this system, there is a heuristic knowledge base of mechanisms which is expressed by membership values and vagueness values based on fuzzy set theory. When design specifications expressed by a frame representation are given, consistency degrees and matching degrees are derived. These two values represent the similarity between the design specifications and the information about various mechanisms in the heuristic knowledge base. By evaluating these two measurements for each possibility, a mechanism is selected for the conceptual design. The effective performance of this system is demonstrated with an example.
