| Outline of Final Research Achievements |
This study has developed numerical methods, which are fast and accurate to find robust optimization solutions whose objective functions are insensitive to various uncertainties in design variables and conditions. For this purpose, this study has proposed a method to reduce high-dimensional design space into a simplified space, a method to approximate various behaviors of the objective function as a non-stationary representation, and a method to adaptively update the approximated objective function with additional evaluations of the true objective function in proper cases. These methods have been applied to real-world design problems, which demonstrate superior effectiveness compared to conventional methods.
