On Four Generalizations of Bags

Abstract

Bags alias multisets have four kinds of generalizations, i.e., R-bags (real-valued bags), F-bags (fuzzy bags), G-bags (generalized bags), and FI-bag (fuzzy interval valued bags). In this paper G-bags and FI-bags are focued upon. We show that they are in a sense isomorphic when traditional fuzzy intervals are slightly modified.
