Abstract
In this paper, we propose a machine design support system using evolutionary techniques. The proposed system creates “machine” which consists of multiple parts. It is composed of two phases: the fundamental-parts-generation-phase, and the machine-generation-phase where the generated parts are combined. On each phase, we use evolutionary techniques, Genetic programming. The system generates parts themselves, uses functional parts in advance, and expresses shape's structure by tree structure. Therefore it is possible to generate various and functional designs. We have implemented the system on PC, and carried out experiments to confirm that various novel objects can be obtained.
