Tourism Facilities as a case study for Group-PAHP Consistency checks during the Covid-19 Epidemic.

The COVID-19 pandemic crisis brought to light the world's tourist systems' high suscep-tibility and defined a scenario marked by significant uncertainty, bad prospects, and per-vasive fragility. In our research, we suggest using MultiCriteria Decision Aiding (MCDA) to examine the possibility of local territorial development through the enhance-ment of the tourism infrastructure. To be more specific, we suggest applying the Parsi-monious AHP (Abastante et al. 2019) for group decisions to study a problem involving the upgrading of tourism facilities. There might be issues with judgment consistency, which would affect the consistency of the matrices as the complexity of the decision-making problem and the number of decision-makers increase (Brunelli and Cavallo 2020a). In the real world, consistency is difficult to attain.
