An incomplete information system is defined as S=<U, A, V >, where U is a non-empty finite set of objects, called universe, A=CD, where C is a non-empty finite set of condition attributes or features, D is a finite set of decision attributes or features, C∩D=. V=Va , where Va , is the set of values of a which may include the null value(with “*” denoted ), called the domain of attribute a.

一个不完全信息系统被定义为S=<U, A, V >,其中U是实物的非空有限集合,称为宇宙,A=CD,其中C是条件的属性或特征的非空有限集合,D是决定的属性或特征的有限集,C∩D=. V=Va ,其中Va ,是a的值的集合,可能包括无效值(以“*”代表),这称为属性a的域。
