摘要
在区间值信息系统中定义了一种新的变精度相容关系,研究了这种相容关系诱导的极大变精度相容类;提出了基于极大变精度相容类的区间值模糊目标信息系统的粗糙集模型;进一步讨论了利用粗糙隶属函数获得决策规则的方法,最后通过实例说明了方法的可行性.
A new variable precision tolerance relation is defined and the induced maximal variable precision tolerance classes in interval valued information system are studied,this paper proposes the rough set model based on the maximal variable precision tolerance classes in interval-valued fuzzy objective information systems.Furthermore,the approaches to decision rules acquisition based on membership function are discussed and finally an example illustrates that the approaches are valid.
