| 摘 要： | 针对优化设计中常见的多目标多约束优化问题，提出了一种求解新方法：利用KS函数的凝聚特性，将优化问题中的全部或部分约束凝聚为一个近似的、逼近精度仅由一个参数控制的约束，然后，再对约束压缩后的优化问题选用适当的约束优化方法求解。仿真结果表明，由于压缩了求解规模，此法收敛稳定且速度快，用于求解一类多目标多约束优化问题具有很好的效果。

| Abstract: | Aimed at the common problems of multi-constraint optimization in optimal design of machinery, a new kind of solving method is presented. By using the agglomeration features of KS function, the total or partial constraints of optimization problems are agglomerated to an approximate and constraint whose precision is controlled by one parameter only. And then a proper constraint optimization method is chosen to solve the optimal problem after the compression of constraints. The geometric explanation of constraints agglomeration is presented by an example of feasible region figure in three dimensional space. |
