中文摘要：

在目前现有的2种质量交换网络综合方法的基础上,本文提出了1种新的基于组分区间法的质量交换网络超结构描述,建立了相应的以总费用最小为目标的质量交换网络超结构数学模型,并用列队竞争算法对该混合整数非线性规划问题（MINLP）进行了求解。为验证本方法的有效性,本文对2个实例进行了求解,求解结果略优于文献结果,说明了本文方法的可行性。

英文摘要：

This paper presents a new statement for the superstructure of Mass Exchange Networks（MEN） based on the intervals,and established the corresopnding mathematical model of MEN with the objective of the minimum cost.Meanwhile,the problem that is a mix integer nonlinear programming（MINLP） is solved using Line-up competition algorithm.To verify its effectiveness,two examples are applied to illustrate the proposed method and the results are superior to those in literature which demonstrate that the approach introduced by this article is feasible.
