At an early stage of design process, it is required to discuss many ideas derived from design requirements using designer's knowledge and experiences. Especially, at conceptual design stage, many designers often discuss together about new product and discuss design ideas considering its effectiveness. However, according to increasing the complexity of the functions of products and variety of consumer's needs in recent years, it becomes difficult for designers to discuss about ideas by only conversations and figures. Then, in the conceptual design process, it is required to derive many ideas that meet the design requirement considering the complicated requirements. The derivation process of ideas often wastes the time because of the inertia of designer's thinking process. In this study, we will propose the method to support derivation process from the visualized relation using Data Envelopment Analysis. Through the experiment, we will confirm the effectiveness of our study.
