“…The objective of sorting the quarries from the most impactful to the least impactful, giving their considerable number, cannot be pursued by solving a ranking type problem (γ problematic) through the ELECTRE III. Instead, it requires the application of a sorting type problem (β problematic), involving the division of quarries into categories based on different levels of impact; this is accomplished through the application of the ELECTRE TRI model [64][65][66]. The software chosen to apply this decision analysis procedure was MCDA-ULaval v0.6.28, developed at the Université Laval of Quebec [67].…”

Quarrying has great importance for economic development and, at the same time, can have several adverse environmental impacts; specifically, it may have a significant influence on water resources. There are approximately 4000 quarries in Italy, and knowledge of their potential impact on water resources is limited. To this end, a procedure for categorizing Italian quarries was devised by combining the methods of Geographic Information Systems and Multi-Criteria Decision Aiding, selecting the potentially impactful criteria, and parametrizing the latter through the available databases. Using the ELECTRE models (ELECTRE TRI and ELECTRE III), the impact category of each quarry was assessed separately for surface water and groundwater and then the overall impact on water resources was assessed. The simulations were carried out by varying the weights of the various selected criteria, which allowed the grouping of Italian quarries into five categories with increasing potential impact on water resources. The ranking of quarries falling into the two highest-impact categories was further refined using ascending and descending distillations. The categorization can be interpreted as a first national assessment of the sustainability of quarrying activities with reference to water resources. The methodological approach of the study proved to be appropriate for the quarry-sorting and -ranking processes, lending itself to the introduction of other criteria and weights, including those arising from the participation of different stakeholders.

A note on ELECTRE TRI-nB with few limiting profiles

ELECTRE TRI-nB is a method designed to sort alternatives evaluated on several attributes into ordered categories. It is an extension of ELECTRE TRI-B that uses several limiting profiles, instead of one, to delimit each category. In a previous paper we have characterized the ordered partitions that can be obtained with ELECTRE TRI-nB, using a simple axiom called linearity. The simplicity of this characterization crucially depends on the possibility to use as many limiting profiles as we like to delimit a category. This is not completely realistic and there is a need to study models in which the number of limiting profiles delimiting each category is restricted. This note starts the investigation of such models. We specifically study the case of models using one or two profiles together with an outranking relation based on unanimity.
