摘要：
This study extends the rough set in interval-valued information systems to the multi-granulation rough set in interval-valued information systems. The lower and upper approximations of a set in interval-valued information systems based on multi-granulations are defined and some basic properties are introduced. In order to substantiate the conceptual arguments numerical examples are given. © 2013 Asian Network for Scientific Information.
