摘要:

针对舰船设计中存在所得方案分布性和收敛性不好等问题，首先建立以初稳性高、飞行甲板面积、横摇固有周期以及阻力为优化目标的大型舰船总体要素优化模型；其次根据大型舰船方案设计的特点，提出一种约束多目标分解进化算法；最后将提出的算法用于优化模型的求解。与目前优化性能较好的2种算法进行对比实验，实验结果表明，本文算法获得了性能更加优异的设计方案。

Abstract:

In view of the fact that the distribution and convergence of the schemes are weak in ship design, this paper established an optimization model for the overall elements of large ship, which contains these optimization objectives such as the initial stability height, the area of flight deck, the natural roll period and the resistance. Then a constrained multi-objective decomposition evolutionary algorithm was presented according to the characteristics of large ship’s scheme design. Finally the proposed algorithm was used to optimize the model. The solution was compared with the two optimal algorithms. The results show that the performance of this method is more excellent.
