Multiobjective optimization using kriging for industrial applications

Abstract

This study demonstrates advances in multiobjective optimization, supporting a robustness study of a simplified jet engine structural model. The ultimate goal is to find the best structural configuration of shell thicknesses along the engine that will be robust to a variety of exgternal loads, will be as light as possible and where fuel consumption will be minimal. These are competitive objectives some of which are stochastic rather than deterministic in nature. The paper demonstrates that a deep level multiobjective search pays off many times the investment in time and money by providing significant design improvemen
