Another interesting article by the N.EA team has been published in the journal Operations Research and Decisions. In this article, we conduct a very detailed analysis of the impact of various behavioral characteristics of decision-makers on their use of different multiple criteria decision-aiding (MCDA) methods and their final opinion regarding recommendations and future use of these methods. The conducted empirical study utilized a proprietary online decision support and survey system, and the data from the system was analyzed using a complex structural model that accounts for both direct and indirect influences of exogenous variables on the final assessment of MCDA methods’ functionality.
