A New Hybrid Method to Solve the Multi-objective Optimization Problem for a Composite Hat-Stiffened Panel

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