In this paper, aiming at the comprehensive optimization of SWATH, we establish a optimization mathematical model of SWATH. And use genetic algorithm to carry out the comprehensive optimization calculation. To solve the problem of premature convergence of genetic algorithm, we adopt parallel strategy to improve the efficiency of the algorism on three design variables: Loa, speed item. In order to improve the parallel efficiency of the algorithm, we have carried out sensitivity analysis propeller diameter, and obtained the analysis results. The research results can provide a reference for the multi-objective, multi-variable and multi-constrained comprehensive optimization of the performance optimization of SWATH.
