Concept Design Method by Combination of Products and Operations

(Report 3: Proposal of optimal design system by the divergence and convergence process)

Abstract

In order to survive in the space market, it is necessary to establish a design method which enables two processes that, one is the generation process of many design plans and the other is the process of searching for a optimum design solution quickly and steady. In this research, we considered the design process to be a repetition of "divergence process" which generates many design plans and "convergence process" to calculate optimal solution. The prototype system based on the design method was implemented, and some examples applied for the concept design of super-sonic vehicle “SEED” were shown.
