abstract = {Delphi multi-round survey is a procedure that has been widely and successfully used
to aggregate experts’ opinions about some previously established statements or questions. Such
opinions are usually expressed as real numbers and some commentaries. The evolution of the
consensus can be shown by an increase in the agreement percentages, and a decrease in the number
of comments made. A consensus is reached when this percentage exceeds a certain previously set
threshold. If this threshold has not been reached, the moderator modifies the questionnaire according
to the comments he/she has collected, and the following round begins. In this paper, a new fuzzy
Delphi method is introduced. On the one hand, the experts’ subjective judgments are collected as
fuzzy numbers, enriching the approach. On the other hand, such opinions are collected through a
computerized application that is able to interpret the experts’ opinions as fuzzy numbers. Finally,
we employ a recently introduced fuzzy ranking methodology, satisfying many properties according
to human intuition, in order to determine whether the expert’s fuzzy opinion is favorable enough
(comparing with a fixed fuzzy number that indicates Agree or Strongly Agree). A cross-cultural
validation was performed to illustrate the applicability of the proposed method. The proposed
approach is simple for two reasons: it does not need a defuzzification step of the experts’ answers,
and it can consider a wide range of fuzzy numbers not only triangular or trapezoidal fuzzy numbers.},
