摘　　要：质量交换网络优化后期,存在结构易固化、新单元生成受限的现象,不利于结构变异和全局寻优。因此,文中首先探究了结构固化的成因,并提出单元活性强化策略。在优化过程中,实时监测个体状态,以一定的概率随机抽取一个超过阈值的质量交换器,并将其分化为多个传质单元,以此增强新生单元的活性和个体结构变异能力,提升算法的全局搜索性能。将改进策略应用于废水脱酚和空气除氨2个算例中,所获结构的年综合费用为129 200、336 148美元/a,均优于目前文献最优解。结果表明:单元活性强化策略可以促进结构优选,有效提升算法优化质量。In the later stages of mass exchanger network optimization,the structure tends to solidify and the generation of new units becomes limited,leading to difficulties in achieving structural variation and global optimization.Therefore,the cause of structural solidification was first explored and a unit activity strengthening strategy was proposed.During the optimization process,individuals status were monitored in real-time.If a mass exchanger exceeds a certain threshold,it is randomly selected with a certain probability and divided into multiple units.This enhances the new unit activity and the individual structural variation capacity,improving the global search performance of the algorithm.The improved strategy was applied to two examples of phenol removal and ammonia removal.The total annual cost of the obtained structures is 129200 and 336148 dollars/a,respectively,both superior to the current literature.The results show that the unit activity strengthening strategy effectively promotes the optimization of the structure and improves the optimization quality.
