Its main goal is to show an alternative way to evaluate the value of appraisal. This alternative consists of making a previous classification of the universe of discourse, that is, the set of potential buyer. REV makes a different evaluation per each class according to their preferences. The tool is developed in Java in a fuzzy framework by means of XFuzzy and it is the continuation of [7].engbook parthttp//doi.org/10.1109/ISKE.2008.4731009http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=4731009&abstractAccess=no&userType=instrestricted access004.8JavaFuzzy logicFuzzy set theoryPricingSoftware toolsInteligencia artificial (Informática)1203.04 Inteligencia Artificial
