| 摘 要： | 针对斜拉桥成桥后的误差调整问题,建立多目标、多约束的优化模型;利用一种带参数的综合凝聚函数法,将多个目标和多个约束分别凝聚为一个替代目标A(x)和B(x),使各个目标和各个约束在A(x)和B(x)中具有不同的权重.通过凝聚函数法,将多目标、多约束的非线性规划问题转化为光滑、可微的单目标、单约束优化问题.数值算例表明该方法可以应用于大规模的非线性规划问题中. |
| 关 键 词： | 斜拉桥 凝聚函数 误差调整 非线性规划 |

| Abstract: | The optimization model of error adjustment with multi-objective and multi-constraint is established by using the integrated aggregate function with parameters.The multi-objective and the multi-constraint are respectively aggregated to A(x) and B(x) with different weight in the substitute.The question of multi-objective and multi-constraint is converted into an optimization with single objective and constraint,which is smooth and differentiable.Numerical example indicates that the method can be used in the l... |
