Optimum height of the core and thickness of the composite faces of a sandwich panel under a defined loading have been computed in order to obtain the lowest weight of structure and its highest stiffness. Either by choosing adequate lay up sequence of multilayer composite faces, desired properties of the composite faces was chosen. The Genetic Algorithm (GA) based on statistics was used and to obtain the best methods of G.A., sensitivity analysis was carried out. In result, the influence of sensitivity analysis was found useful because it leaded to a better convergence of problem and decreased the execution time of the problem.
