Multi-objective design exploration using efficient global optimization
Shigeru Obayashi · Research Repository (Delft University of Technology) · 2006
Multi-Objective Design Exploration (MODE) and its application are presented. MODE reveals the structure of the design space from the trade-off information and visualizes it as a panorama for Decision Maker. As an optimizer for MODE, Efficient Global Optimization (EGO) based on the Kriging model has been extended to Multi-EGO to solve multi-objective problems, which allow using Multi-Objective Genetic Algorithms efficiently. The resulting MODE was applied to the multi-disciplinary wing design problem and revealed the detailed trade-off information about aerodynamic and structural performance successfully.
