Fuzzy Multicriteria Decision Making Model for HPP Alternative Selection
In decision making models developed using the Analytic Hierarchy Process, expert judgments expressed verbally are quantified using the Saaty’s scale in the way that they were assigned strict values (crisp numbers). As expert judgments are not really strict, there is a need for these judgments to be more properly quantified. Instead of strict values, they need to be assigned fuzzy numbers. In this paper a fuzzy model for multicriteria decision making on the selection of the best alternative from the Pareto set of technical solutions for the hydroelectric power plant is developed using a Fuzzy Analytic Hierarchy Process. The model is tested on a concrete example and the results are compared with the results of a model developed using the classic Analytic Hierarchy Process.
