区间值信息系统是单值信息系统的的一种推广,知识约简是粗糙集理论的核心问题之一.在基于优势关系下的不协调区间值信息系统中引入了分布约简和最大分布约简的概念,进一步建立了分布约简和最大分布约简的判定定理和辨识矩阵,从而利用辨识矩阵给出了在优势关系下不协调区间值目标信息系统分布约简的具体方法.
Interval value information system is a kind of promotion of single value information system, and knowledge reduction is one of the core problems of rough set theory.Distribution reduction and maximum distribution are introduced in the discordant interval value information system based on superiority relations In addition, the judgment theorems and the identification matrices of distribution reduction and maximum distribution reduction are further established. By using the identification matrix, a concrete method for reducing the distribution of disjoint interval value target information systems is given.
