The main result of this paper shows that A(C) characterizes the degree to which C is full rational. We also obtain a method for computing A(C). The Arrow index allows to rank the fuzzy choice functions with respect to their rationality. Thus, if for solving a decision problem several fuzzy choice functions are proposed, by the Arrow index the most rational one will be chosen.<\/jats:p>","DOI":"10.3233\/fi-2010-248","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T23:29:09Z","timestamp":1575329349000},"page":"245-261","source":"Crossref","is-referenced-by-count":4,"title":["Arrow Index of a Fuzzy Choice Function"],"prefix":"10.1177","volume":"99","author":[{"given":"Irina","family":"Georgescu","sequence":"first","affiliation":[{"name":"Academy of Economic Studies, Dept. of Economic\r\t\t\t Cybernetics, Piata Romana No 6, Bucharest, Romania.
