| 摘 要： | 建立了船舶坐墩配墩多目标优化设计的数学模型．选择墩木总体积和船舶尾部结构的强度储备作为目标函数，采用宽容排序法求解所建立的多目标优化模型．计算示例表明，多目标优化设计方案的墩木总体积虽较单目标优化设计结果有所增加，但船舶尾部结构强度储备亦明显增加．多目标优化设计方案同时兼顾协调了两个不同性质的性能指标，使得设计更为合理．

| Abstract: | A mathematical model for multi-objective optimization of docking blocks was described. The total volume of the blocks and the strength reserve of ship structures of a stern were chosen to be the objective functions. The modified lexicographic method was employed to find the optimal solution. The numerical simulations showed that the strength reserve obtained from multi-objective optimization was increased although the total volume of blocks is also increased more than that of the single objective optimization. The application of multi-objective optimization can make design scheme more reasonable. |
