Fuzzy value is a fuzzy set on the interval [0, 1], alpha-cuts of which are
closed intervals. In this note we define several operations of Fuzzy values
, which will be useful in diverse fields of both theoretical and applicativ
e aspects. Further we introduce two kinds of order relations between fuzzy
values, and investigate on the least upper bound and the greatest lower bou
nd with respect to these orders. (C) 1999 Elsevier Science B.V. All rights
