| 中文摘要 |
| 提出了一种改进的权重自适应方法，并以遗传算法为基础对冷连轧轧制规程进行多目标优化。首先，结合某冷轧厂实际的轧制规程优化过程，选取等功率裕量、轧制能耗及带钢打滑概率作为优化目标，建立了冷连轧轧制规程的多目标优化模型。然后将改进的权重自适应GA应用于不同规格的带钢轧制规程多目标优化中，结果表明，与实际应用的轧制规程相比，该方法有效的降低了3个目标函数的值；与权重自适应GA相比，改进的权重自适应GA的针对性更强，同时重要性高的目标收敛速度更快。 |

| A improved adaptive weight approach is proposed, and it is applied to rolling schedules multi-objective optimization of tandem cold rolling based on GA. According to actual rolling schedules optimization process, power distribution, rolling energy consumption and slip rate are selected as objective functions, then the multi-objective model of rolling schedules is established. Applying the improved adaptive weight approach GA to optimize rolling schedules of different specifications strips, optimization result shows the proposed optimization method decreases the value of three objective functions simultaneous compared to actual rolling schedules; it is more targeted and makes the object with higher priority has the faster convergence speed compared with the adaptive weight approach GA. |
