Robust Optimum Design by Statistical Design Support System

Abstract

The authors have proposed Statistical Design Support System(SDSS)which can be used even on nonlinear behavior. It is an integrated system based on the Response Surface Methodology and the Design of Experiments. The optimization can be performed with this system using small number of case studies. In this paper, they treated with an uncertain variable(an error variable)which the engineering designers cannot control and certain variables(design variables)which the engineering designers can control. In this study, a new robust and optimum design approach was proposed by using SDSS.Using this method, a structure can be optimized for the objective functions without losing the robustness toward the uncertain variable. The application results verify the usability of the approach and SDSS.
