| 中文摘要: |
| 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． |
| 英文摘要: |
| 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 large scale non-linear programming. |
