The aim of this paper is to study the fuzzy measures proposed by Butnariu [
1-3]. First, the concept of fuzzy orthogonal measure on a regular fuzzy mea
surable space is presented. Then, the structural characteristics of fuzzy o
rthogonal measure, which shows the relation between the classical finite me
asure and the fuzzy orthogonal measure, is demonstrated. Finally, the weak
convergence of fuzzy orthogonal measures is investigated. (C) 2000 Elsevier
