| 英文摘要 | 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.; 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 systems,and some related properties are discussed.Finally,the results of practical examples show the effectiveness of the proposed system.; 国家自然科学基金项目(10971186;11061004);福建省教育厅A类重点项目(JA10202) |
