FUZZY APPROACH FOR GROUP DECISION-MAKING IN CRISIS SITUATIONS

The importance of correct and clear decisions during a complex difficult situation is very easy to understand, but not so achieve. Especially in situations where decision-makers must decide under time pressure uncertainty. For instance, typical crisis have such characteristics. Given the uncertainty, subjectivity ambiguity human knowledge, are also characterized by conflicting interests. In this article, we propose an approach based on fuzzy set theory help find collective decision considering weights each member decision-making group. More specifically, proposed uses new innovative transformation numbers through α-level cuts. key role process played shape position numbers. Additionally, Hamming distance will be used for final interpretation results, order minimize loss information caused defuzzification.
