The coordination index of finite collection of fuzzy sets
This paper introduces a concept of the coordination index of finite collection of fuzzy sets. The uniqueness of the representation of this index in metric lattice of fuzzy sets with continuous isotone estimation has been proved. The correlation between isotone estimations of fuzzy set and its nearest usual set has been determined. (C) 1999 Elsevier Science B.V. All rights reserved.
