Abstract |
The roughness of a set (according to the notion introduced by Pawlak in 1991) can be regarded as the MZ-distance between its upper and the lower approximations. With this idea in mind, we have generalized Pawlak s definition, by replacing the MZ-distance by a general distance measure. We also generalize the notion of roughness of fuzzy sets introduced by Huyhn and Nakamori in 2005.
