Generalized rough multiset via multiset ideals

摘要: In this paper, ideals in the context of multisets on lattice all submultisets with order relation as multiset inclusion have been introduced. Moreover, generalization rough model by defining new approximation operators more general setting via ideal has presented. The concepts lower and upper approxima- tions mentioned. These definitions decrease increase hence decreasing boundary region increasing accuracy measure. Properties these approximations are studied various examples Also, comparison between defined Girish John (11, 12) current It's therefore shown that generally. Finally, topology induced present methods is finer than old method 12).
