| Authors: | FENG Tao MI Ju-Sheng |
| Abstract: | This paper proposes a novel pair of induced IF covering approximation operators in an IF coveting approximation space,and discusses some basic properties about definable IFSs.A measure is defined to describe the uncertainty of IFSs in IF coveting approximation spaces.Finally,we study the properties of reductions of an IF covering respectively based on induced IF covering approximation operators and IF covering approximation operators. |
| Keywords: | IF coveting induced IF lower and upper approximation operators reduction uncertainty |
