摘要
知识的属性扰动引起知识规律的变化,这些变化的规律称为扰动规律。利用单向S-粗集和单向S-粗集对偶,给出属性扰动的知识规律的上规律、下规律的概念,并对知识规律与属性扰动的知识规律进行了讨论,提出了属性扰动知识规律(上规律,下规律)的不等式定理。
The attribute disturbance of knowledge causes the changing of the knowledge law,and the changing laws are called disturbance laws.By using one direction S-rough sets and dual of one direction S-rough sets,the concepts of knowledge upper law and knowledge lower law of attribute disturbance were given,knowledge law and the knowledge law of attribute disturbance were discussed,and the inequality theorems of attribute disturbance knowledge upper law and attribute disturbance knowledge lower law were proposed.
