Multi-objective optimization of rolling schedules for tandem cold rolling based on adaptive weight differential evolution algorithm

摘要

According to the demands of actual rolling schedules designing, power distribution, rolling energy consumption and slip rate are selected as objective functions. Then the multi-objective model of rolling schedules is established. An adaptive weight differential evolution algorithm is proposed for multi-objective optimization. And it is applied to rolling schedules multi-objective optimization of tandem cold rolling. The result shows that the proposed method decreases the values of three objective functions simultaneously compared to actual rolling schedules.
