選好度を基盤とする多目的同時満足化設計手法

（経験知識，有向グラフ，製品の使用状態に基づく設計変数選好度分布の与え方）

In the multi-objective simultaneous satisfaction design method (set-based design method) based on the preference degree, the distribution of preference numbers regarding the performance as the ability of the function and the design variable as the influential factor have conventionally been based on empirical knowledge. In addition to this, in this study, I investigated a method based on directed graph theory (adjacency matrix and governing matrix) and a method based on the frequency of actual product usage as characteristics of the design variables. In particularly, for the of cases of graph theory and the frequency, the methods expressing the preference distribution are shown using actual concrete examples, that are driving conditions of a car and material properties, respectively.
