Abstract
AbstractIn [16], negation of fuzzy information were distinguished as contradictory negation, opposite negation and medium negation, and proposed a fuzzy propositional logic with contradictory negation, opposite negation and medium negation (FLcom). In order to show that FLcom is applicable for handling fuzzy proposition and its different negations, this paper studied the application of FLcom to fuzzy decision making in an example. We presented an approach to formal representation of fuzzy proposition and different negations in decision rules, and the measure of truth value of fuzzy proposition and threshold of truth value. Finally, we discussed reasoning and realization on fuzzy decision making in the example based FLcom and the fuzzy production rule.Keywordsfuzzy propositional logiccontradictory negationopposite negationmedium negationfuzzy decision making
