Mass Exchange Network Mass Transfer Load Infeasibility Treatment and Dynamic Regulation Strategy

本文分析了惩罚函数法处理传质约束对质量交换网络优化带来的消极影响,提出一种传质负荷动态调控策略,采用不同的调控方式处理单元传质约束,即衰减违反传质约束单元的传质负荷或消除单元,以保证结构中的传质单元不违反约束。通过两个质量交换网络算例进行验证,所得结果相比文献最优结果分别下降2943$·a^(-1)和1697$·a^(-1),且结构中传质单元数量增加,证明了策略的有效性。

In the optimization of mass exchange networks with mass transfer load as the optimization variable,using the penalty function method to deal with infeasible solutions that violate the feasible constraints on mass transfer will limit the generation of mass transfer units,and at the same time bring negative effects on the optimization algorithm’s optimization path.In view of this,the negative impact of the penalty function method to deal with mass transfer constraints on optimization is analyzed,based on which a dynamic regulation strategy of mass transfer load is proposed to deal with the units mass transfer constraints by using different regulation methods,attenuating the mass transfer load of the units that violate the mass transfer constraints or eliminating the unit to ensure that the mass transfer units in the structure not violate the constraints.The validation is carried out by two mass exchange network arithmetic examples,and the obtained results demonstrate the effectiveness of the strategy by decreasing 2943$·a^(-1) and 1697$·a^(-1),respectively,compared with the optimal results in the literature,and increasing the number of mass transfer units in the structure.
