interval-valued fuzzy number; algebraic properties; distance measure
In this paper, we generalize results of Wang and Li [Fuzzy Sets and Systems 98 (1998) 331] on interval-valued fuzzy numbers and extend their operations with simple proofs. We also consider some algebraic properties and a distance measure for interval-valued fuzzy numbers. (C) 2002 Elsevier Science Inc. All rights reserved.
