Multiple-Source Approximation Systems:Membership Functions and Indiscernibility

摘要：

The work presents an investigation of multiple-source approximation systems,which are collections of Pawlak approximation spaces over the same domain.We particularly look at notions of definability of sets in such a collection μ.Some possibilities for membership functions in μ are explored.Finally,a relation that reflects the degree to which objects are (in)discernible in μ is also presented.
