摘要
本文在分析不完备信息系统已经存在的容差关系、非对称相似关系、限制容差关系以及特征关系的基础上,提出了对象间完备度的概念,并建立了基于对象间完备度的限制容差关系模型,最后通过实例分析说明此模型可以更加真实客观地处理不完备信息系统。
In this paper,several extensions of rough set under incomplete information systems,such as tolerance relation,non-symmetric similarity relation,limited tolerance relation and characteristic relation,are analyzed.Then a concept of inter-object completed degree is proposed and limited tolerance relation model improved based on inter-object completed degree is established.Finally,an example is given to illustrate that this model can deal with incomplete information systems more objectively.
