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。
In view of the fact that the distribution and convergence of the schemes are weak in ship design, this pa- per established an optimization model for the overall elements of large ship, which contains these optimization ob- jectives 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 com- pared with the two optimal algorithms. The results show that the performance of this method is more excellent.
