209 設計者の設計意図の考慮と多目的満足化を実現するセットベース設計手法

抄録

The conceptual design phase contains multiple sources of uncertainty in describing design, and nevertheless the decision-making process at this phase exerts a critical effect upon drawing a successful design. The proposed preference set-based design method, consisting of set representation, set propagation, set modification, and set narrowing, which enables the flexible and robust design while incorporating designer's intention. In contrast to the conventional optimization techniques, this method generates a ranged set of design solutions that satisfy changing sets of performance requirements. This paper presents the applicability of our proposal for obtaining the multi-objective satisfactory design solutions by applying to an automotive front-side frame.
