Abstract
In order to develop design support system from initial design stage to detail design stage, Topdown Oriented Design Method is assumed to be available. The authors developed Topdown Oriented Design System, in which the design model is expressed by the concepts of "Entity, Attribute and Relation Model" . One of the important purposes of the Topdown Oriented Design System is to describe design processes in computer system. It is valuable if the design support system can evaluate the design processes of designers and informs the designers of the unsuitable results of design process. In this paper, the authors suggest the frameworks of the evaluation methods for the design process by using QFD, Quantification Theory III, DSM and ISM in Topdown Oriented Design System.
