Abstract

In order to provide efficient algorithm for multidisciplinary design optimization of complex coupled systems, a distributed coevolutionary multidisciplinary design optimization algorithm is proposed. The algorithm imitates the biological competitive and cooperative coevolutionary process in ecological systems. The ideas of decomposition and cooperation in coevolutionary algorithm combine with the ideas of decomposition and synergism in MDO. Based on the method of domain decomposition and the implicit iteration strategy, the complex coupled system is decomposed into relatively independent and autonomic multidisciplinary systems. Each discipline is modeled as a species. Thus the competitivecooperative adaptive coevolutionary multidisciplinary optimization process has been modeled amongst the populations of multidisciplinary species. For illustrating the proposed algorithm, a multidisciplinary design optimization test problem generated by a robust simulator called CASCADE is utilized to simulate. Experimental results reveal the proposed algorithm has good search capability and convergence performance. Hence, the presented algorithm is efficient and robust in solving multidisciplinary design optimization problem of complex coupled systems.
