| 摘 要： | 介绍集值信息系统和区间值信息系统,并提出了同时具有这两种系统特点的区间集值信息系统.依据属性值的语义关系,将区间集值信息系统分为两类：析取（I型）和合取（II型）系统,并对其分别提出了基于优势关系的粗糙集模型,讨论了相关性质.最后用实例分析验证了所提出系统的有效性.

| Abstract: | This paper respectively introduces set-valued information systems and interval-valued information systems,and presents interval and set-valued information systems which have common features of above two systems.According to the semantic relation of attribute values,interval and set-valued information systems can be classified into two categories,disjunctive(type I) and conjunctive(type II) systems.Then,a dominance-based rough set model is presented for these two types of interval and set-valued information ... |
