A two-level procedure based on genetic algorithms to optimize an aeronautical composite structure

Optimal design of complex engineering systems, such as aircraft composite structures, can often be accomplished only by applying decomposition techniques. In this paper, the optimal design of a composite wing-box is addressed by using a two-level scheme based on the Genetic Algorithm meta-heuristic. The two-level optimization strategy was evaluated for variations both in the angular step of the composite layers and in the strength of material.
