Abstract

We provide a methodology to perfom an extensive and systematized analysis of problems where experts voice their opinions on the attributes of projects through a hesitant fuzzy decision matrix. A weighted average of specific parametric expressions for two tenable indices of satisfaction permits to give a profuse picture of the relative performance of the projects. When the parameter grows, these indices tend to replicate the evaluation by respective simplistic expressions that only depend on the least, resp., the largest, evaluation and the number of evaluations in each cell. This provides the decision-maker with ample information on which he or she can rely in order to make the final decision.
