摘　　要：采用多目标遗传算法(MOGA)和多属性决策理论,针对潜艇环肋圆柱壳在静水压力作用下的多目标离散优化问题进行了研究,讨论了与潜艇结构强度设计有关的应力量和失稳载荷与质量之间的关系,给出了不同目标之间的Pareto前沿。基于无偏好信息情况下的排序挑选出最优解,并且和经典的单目标最优解进行了比较分析。Based on multi-objective genetic algorithms（MOGA）, a study of multi-objective optimization design of circular cylindrical shell under hydrostatic pressure is performed in this paper. The scatter graphs of 6 objectives are obtained. The relation of strength stresses and critical loads to the mass is in detail evaluated and Pareto frontiers are given then. The non-linear utility functions are used to solve the multi-attribute decision making problem. The ranking of Pareto solutions is proposed. The solution obtained by author is compared with that from a single objective problem （SOP）.
