Abstract

A design system (1) is provided with a function of acquiring a design specification of an object to be designed and an evaluation index for evaluating a value of the object to be designed in the design specification; a function of acquiring profile data of the object to be designed; a function (design order determining section (12)) of extracting entity design elements and important design variables from the profile data and prioritizing the entity design elements and the important design variables so as to construct a design workflow; a function (evaluation approach construction section (13)) of constructing an evaluation formula for performance/evaluation of a design result of each of the entity design elements in conformity with the design workflow; a function of finding an appropriate solution by performing automatic optimization while evaluating the design result with use of the evaluation index in accordance with the design workflow with which the evaluation formula is associated; and a function of outputting the appropriate solution thus found. This allows the object to be designed to be parametrically handled, and makes it possible to create a design workflow for efficiently finding an optimum design solution by properly combining a series of design elements and to find an appropriate solution with the use of the design workflow.
