Abstract
At the early phase of design, there are many uncertain information, and design information becomes clear as design progresses. The decision making of designers at the early phase of design has a significant influence on the latter half of the design. However, the required performance often changes due to the design change at this phase, therefore, it is difficult for the designer to make appropriate decisions. In the conventional design method, design solutions are derived by defining design variables as point values and iteratively calculating until the defined required performance is satisfied. In order to support designers’ decision-making, this paper derives various range solutions that satisfy multi-objective requirements and purposes the indices that evaluate the robustness of performance, the desirability of performance, and the desirability of design variables, and the design intent of the designer is visualized. The effectiveness of the proposed decision-making support system is demonstrated by applying it to the case of one degree of freedom vibration system.
