Abstract: Entropy theory is an effective tool for studying uncertainty.Based on a pre-order relation defined on an set-valued information system,rough entropy was proposed.The maximum and minimum values of rough entropy were shown.And the monotony of rough entropy was also proved.
Key words: Set-valued information system, Prcorder relation, Information granule, Rough entropy
