A characterization of a general class of ranking functions on triangular fuzzy numbers
This paper aims to the discussion of properties for ranking fuzzy numbers. An approach of axiomatic type is followed providing the definition of two groups of requirements which characterize a ranking function through its behaviour on triangular fuzzy numbers. Particularly, the problem of making the evaluations on triangular fuzzy numbers sensitive to their spread has been deeply analyzed. (C) 2003 Elsevier B.V. All rights reserved.
