Ordering fuzzy numbers using the centroid: Practical aspects

Abstract

This paper corresponds to the second part of the study exploring the ordering of fuzzy numbers with the purpose of supporting the database queries configuration. In the first part: a new proposal was presented comparing two fuzzy numbers using the centroid abscissa; and it was shown to be a total order relation.  In this second part: study cases are addressed that include a vast diversity of possible situations for comparison fuzzy numbers with different representations; a Haskell implementation of the proposed method is presented; and thus, we demonstrate its adaptation to human intuition.
