基于Pareto解的多目标优化方法NSGA-II应用至潜器的快速性与操纵性综合优化设计之中。通过回转体潜器阻力性能的数值计算结果建立了阻力的近似计算模型，并与系列模型试验结果进行了比较；通过估算潜器的水动力系数，根据水平面线性运动方程得出水平面操纵运动稳定性和机动性的衡准指标。优化后，得到了阻力与回转直径的Pareto最优解的散点图，设计者可针对不同需求的潜器，从中进行选择，保证了Pareto最优解对应的每一艇型设计方案在满足操纵性要求下阻力最小，或在该阻力值的条件下操纵性最优。

The multi-objective arithmetic NSGA-II based on Pareto solution is investigated to deal with integrated design of resistance and manoeuvring performances for submersible. Approximation model of drag for serial revolution shapes is constructed by hydrodynamic numerical calculations, and the precision of re-sponse surface model is validated by compared with the result from experiment of serial models in circular flume. The appraisement criterion of stability and mobility are calculated from linear equation of horizontal movement by estimating hydrodynamic coefficients of submersible. After optimization, the scattered Pareto solution of drag and turning diameter is gained, and from these the designer can choose the reasonable one from the actual requirement which can ensure the minimum drag in this manoeuvring performance or the best manoeuvring performance in this drag value.
