知识约简是概念格理论的核心问题之一.主要讨论协调区间值决策形式背景的知识约简问题.首先从经典的协调决策形式背景出发,定义了协调区间值决策形式背景,同时给出了协调区间值决策形式背景上决策保序集的定义和判定定理,并进一步阐明了决策保序集和协调集之间的关系,然后通过定义辨识矩阵,给出了协调区间值决策形式背景的属性约简方法.
Knowledge reduction is one of the core issues in concept lattice theory, and it mainly discusses the problem of knowledge reduction that reconciles the context of interval value decision.Firstly, from the background of classical form of coordination decision, we define the formal context for the coordination of interval value decision-making, Coordinate the definition and judgment theorems of decision-making sets in the context of interval value decision-making, and further clarify the relationship between the decision-making set and the coordination set. Then by defining the identification matrix, the properties of coordinating the decision- Reduction method.
