A new hybrid method to solve the multi-objective optimization problem for a composite hat-stiffened panel

Abstract : In this paper we present a new hybrid meta heuristic by combining Multi-objective bat algorithm (MOBA) and variable neigh- borhood search (VNS). The hybrid meta heuristic is coupled with re- sponse surface methodology (or meta modeling) to solve the mechanical multi-objective optimization problem of hat stiened composite panel. The optimization criteria were the weight and the rigidity of the panel. Experimental results show that our suggested approach is quite eective, as it provides solutions that are competitive with the results obtained by using MOBA alone.
