This seminar discusses a new approach, Multi-Objective Design Exploration (MODE), for Multidisciplinary Design Optimization (MDO). Typical MDO problem involves competing objectives, for example in the aircraft design, minimization of aerodynamic drag, minimization of structural weight, etc. While single objective problems may have a unique optimal solutions, multi-objective problems (MOPs) have a set of compromised solutions, largely known as the trade-off surface, Pareto-optimal solutions or non-dominated solutions. Thus, the aim of the MODE is not to find an optimal solution but to reveals the structure of the design space from the trade-off information and visualizes it as a panorama for the decision making (DM).
Main components of MODE are search engines for the non-dominated front and data mining techniques. Adaptive Range Multi-Objective Genetic Algorithms (ARMOGA) is used as search engine and Self-Organizing Maps (SOM) and Analysis of Variance (ANOVA) are used for data mining.
MODE has been applied to a MDO problem for a regional-jet wing in cooperation with Mitsubishi Heavy Industries, Ltd. under the small jet aircraft R&D project sponsored by the New Energy development Organization of Japan (NEDO). Detailed results will be shown in the presentation.
