摘要： 阐述直觉模糊S-粗集和直觉模糊S-粗集副集的数学结构与特性。针对空间群的动态性，用一个双向直觉模糊S-集合表示一个空间群，群中的动态目标构成直觉模糊S-粗集的副集。给出基于直觉模糊S-粗集副集的目标合群算法，对空间群中发现新目标、目标合群等动态操作过程进行分析。通过实例证明该方法的正确性和有效性，计算结果表明该方法能较灵活地处理目标编群中的动态问题。

Abstract: This paper expatiates the mathematics structures and characteristics of intuitionistic fuzzy S-rough-set and the assistant set of intuitionistic fuzzy S-rough-set. Aiming at the dynamic nature of space group, a space group is described with a bidirectional intuitionistic fuzzy S-set, and its dynamic targets compose of the assistant set of intuitionistic fuzzy S-rough-set. Target gregariousness algorithm based on assistant set of intuitionistic fuzzy S-rough-set is proposed, and the dynamic operation process about new target detecting and target gregariousness is analyzed. The correctness and validity of this method are verified by example. Calculation results show that the method can dispose the dynamic problems of target grouping flexible.

Key words: intuitionistic fuzzy S-set, intuitionistic fuzzy S-rough-set, assistant set, target gregariousness
