Existing extensions of rough set model are analyzed in this paper under incomplete information system. This paper modifies limited tolerance model proposed by Wang Guoyin as far as the limitation on relaxation and restriction of condition constraint is concerned. Compared by example, the modified model based on limited tolerance model shows that it is more applicable, reasonable and effective when the universe of discourse is partitioned into tolerance classifications. |
