AB  - This chapter presents a novel multilevel strategy that includes progressive failure analysis and robust design optimization for composite stiffened panels. A multiobjective approach is adopted for the structural sizing of aerospace components at different design stages or levels. The approach is integrated at two design levels, labelled as preliminary design and detailed design. The robust multilevel design methodology integrates the structural sizing to minimize the variance of the structural response. This method improves the product quality by minimizing variability of the output performance function. This innovative approach mirrors the steps taken during design and structural sizing in industry where the manufacture of the final product follows an industrial plan that goes from the material characterization up to trade constraints, through preliminary analysis and detailed design. A composite stiffened panel is optimized to validate the developed methodology. The initial architecture is defined at the preliminary design level by generating a Pareto front, for competing objectives, that is used to choose a design with a required weight. The ultimate load, that the postbuckled panel can bear, is maximized for the chosen weight. Then a robust solution is sought in the neighbourhood of this solution to finally find the layup for the panel capable of bearing the highest load for the given geometry, boundary conditions and optimization constraints.
