For the second aim, two different MCDA-based techniques for the selection of the best alternative were simultaneously used and compared: (1) the Simple Additive Weighting (SAW) (Ching-Lai and Kwangsun, 1981) as multi-criteria technique to define alternatives priorities, coupled with the Paired Comparison Technique (PCT) (Mondy and Noe, 2008) as a means of evaluating criteria priorities (shortly “SAW–PCT”); (2) the AHP as a MCDA technique coupled with the Priority Scale Weighting (PSW) tool (De Feo and De Gisi, 2010) in order to evaluate criteria priorities (shortly “AHP–PSW”). Details on the cited MCDA techniques are given in the methodological section.
