| 摘 要： | 本文研究基于对象定向概念格和属性定向概念格协调决策形式背景属性约简的问题。首先介绍了协调决策形式背景属性约简的概念,讨论了其等价的定义。进一步给出了属性约简的判定定理和相应的可辩识属性矩阵,从而为概念格中协调决策形式背景属性约简提供了一种具体的方法。

| Abstract: | Basing on the object oriented concept lattice and the attribute oriented concept lattice, this paper deals with approaches to attribute reduction in consistent decision formal context.The concepts of attribute reductions in consistent decision formal context are first introduced and their equivalent definitions are given.In addition,we propose theory of knowledge reduction based on consistent decision formal context and give the judgement theorems and discernibility matrices,from which methods of attribute reduction in consistent decision formal context can be derived. |
