Abstract

Abstract: This paper deals with consistent decision formal context and the attribute reduction in it.A relation based on formal context is defined here.In addition，this paper proposes theory of knowledge reduction based on consistent decision formal context and gives the judgement theorems and discernibility matrices，from which methods of attribute reduction in consistent decision formal context can be derived.

Key words: consistent decision formal context, decision consistent set, decision attribute reduction, discernibility matrices

摘要： 主要讨论协调决策形式背景的属性约简。首先定义了形式背景基础上的二元关系，并给出了协调决策形式背景，决策约简的定义。同时，给出了决策可辨识矩阵，得到协调决策形式背景知识的约简方法。

关键词: 协调决策形式背景, 决策协调集, 决策约简, 可辨识矩阵
