| Outline of Final Research Achievements |
In engineering design optimization, robust solutions (designs) with a small influence of noises are often employed even if their evaluation values are slightly worse than other candidate solutions. For noisy multi-objective optimization problems, this work designed an evolutionary optimization framework which the decision maker can consider not only evaluation values of each solution but its noise levels to select the final solution from the obtained solution set. First, this work proposed a method to approximate the optimal trade-off among multiple objectives and their noise levels. Next, since the number of noises should be minimized is increased with increasing the number of objectives, this work also proposed evolutionary many-objective optimization techniques. Furthermore, a decision making support user interface to effectively show high-dimensional vectors involving multiple objective values and their noises was proposed.
