Abstract

Abstract: Based on tolerance relation and dominance relation in literature[7]，a model of k-degree limitation tolerance relation was proposed.Meanwhile the properties were investigated.Finally，a practical case study has proved the feasibility of the model，the result of classification was more suitable to the fact.

Key words: Rough Set, set-valued information system, limited tolerance relation

摘要： 基于文献[7]中的相容关系和优势关系，提出了一种k度限制相容关系模型，同时研究其性质。最后通过实例验证该模型具有很好的灵活性，分类结果也更加切合实际。

关键词: Rough集, 集值信息系统, 限制相容关系
