Abstract
In design of products especially for public use such as automobile, and PC, the requirements become widely spread. Thus, we should have to estimate products by using multi-objective optimization, and it should be estimated in scalar value. In such cases, Data Envelopment Analysis (DEA) works very well. In this study, we analyze the growth of frontier of products and try to estimate the future requirements for the product design. In order to demonstrate the proposed method, we apply it to the growth of Japanese Car for eight years. From those results, we show the growth the frontier for specific class of cars, and also we show the shifts of requirements by shifts of frontier for other specific class of car. And also the necessary condition for product designs is evaluated from the management-side. The above also considers feedback in a conceptual design stage.
