Nowadays, global decisions have to be made in economic, technical, political, military and other areas. The implementation of this kind of decisions requires huge financial and other resources but their consequences have a strong impact on large groups of people. Subjective reasonings and evaluations in such tasks are, as a rule, vague and implicit by nature. Fuzzy set theory seems to be a proper tool for managing this kind of information. This paper provides a brief description and analysis of two popular approaches to decision making under risk in a fuzzy environment.

Keywords
Analytical Hierarchy Process (AHP), Fuzzy Analytical Hierarchy Process (FAHP), comparison of triangular fuzzy numbers, fuzzy weights for criteria, fuzzy preference relations
