摘要: 首先给出直觉模糊映射的定义, 并考察直觉模糊β-覆盖在该映射下的不变性; 然后分别给出映射关于直觉模糊集和直觉模糊β-覆盖相容的概念, 并讨论相关性质; 最后提出直觉模糊β-覆盖信息系统及其同态的概念, 并研究直觉模糊β覆盖信息系统间同态的性质.

关键词: 直觉模糊映射, 直觉模糊β-覆盖, 直觉模糊β-覆盖信息系统, 同态

Abstract: Firstly, we gave the definition of intuitionistic fuzzy mapping  and investigated the invariable properties of intuitionistic fuzzy β-covering under the mapping. Secondly, we gave  the concepts of the mapping about intuitionistic fuzzy sets and intuitionistic fuzzy β-covering compatibility, respectively, and discussed the related properties. Finally, we proposed the concepts of the intuitionistic fuzzy β-covering information system and their homomorphism, and  investigated properties of the homomorphism between the intuitionistic fuzzy β-covering information systems.

Key words: intuitionistic fuzzy mapping, intuitionistic fuzzy β-covering, intuitionistic fuzzy β-covering information system, homomorphism
