Abstract
In this paper, a new framework for conceptual design support in the field of Computer Aided Design of manufacture is proposed. In the framework, an interactive approach between human and system is introduced, which is named Interactive Genetic Algorithm. Users evaluate pairs of tableware, which are generated as chromosomes by the system, based on the subjective feeling. Then the system re-generates next generation candidates based on the evaluation results. Repeating the interaction, users can acquire pair of tableware which reflects users' concept.
