In the settlement transformation process, the number of evaluation elements (criteria, sub-criteria and alternatives) depends on the nature of the different decision-making problems [ 8 , 30 , 36 40 ]. The numeric configuration of evaluation elements (Table 2 ) is generally decided by the person responsible for the evaluation process before the selecting the most suitable MCDA method with reference to the specific problem in hand. In the case of settlement transformation processes, which are generally rather complex, the number of criteria and sub-criteria are defined by the process manager (Responsabile del Procedimento), role regulated by the Legislative Decree 50/2016 Article 31. This is the individual who “provides the authority offering the contract with the data and information regarding the main stages of the intervention, necessary for the coordination, guidance and checks of the correct implementation, and oversees the economic management of the intervention” (Legislative Decree 50/2016 Article 31, par. 4, point f). This kind of activity has been present since the definition of administrative acts relating to settlement process initiation. The person responsible for the evaluation process must attempt to construct the set of evaluation elements without allowing the potential repercussions to overly influence the selection of an MCDA method. Although the creation of the set of variables must of course represent the maximum number of requirements with the minimum number of possible elements [ 35 , 41 , 42 ]. The number of alternatives can be deduced by taking into account what has happened in the past in similar settlement proceedings in the same or in other administrative contexts [ 43 , 44 ]. The typology of the indicators (Table 3 ) varies in accordance with the decision-making problem to be resolved and the context in which it arises.
