信息系统之间的通信是粒计算的一个基本问题。在当前的研究中,需要信息系统之间的同态映射。本文提出了两个宇宙之间的一般关系映射的概念,以便根据给定的另一个宇宙上基于包含度的等价关系来构造一个宇宙上的等价关系。研究了映射的主要性质,证明了在给定条件下原系统和图像系统的属性约简是等价的。最后,我们还定义了两个模糊信息系统之间的模糊一般关系映射的概念并给出了一些性质。
Communication between information systems is a basic problem in granular computing. In current research, a homomorphism mapping between information systems is required. In this paper, the concept of the general relation mapping between two universes is proposed in order to construct the equivalence relation on one universe according to the given equivalence relation on the other universe based on the including degrees. The main properties of the mapping are studied, and it is proved that attribute reductions in the original system and image system are equivalent to each other under the given conditions. Finally, we also define the concept of fuzzy general relation mapping between two fuzzy information systems and give some properties.
