the DMs need to able to justify their choices concerning the location of disposal sites
through systematic, transparent and sustainable processes.
The third case study is a simulated academic process for the transformation of the
Tür und Taxis district in Brussels (Belgium) (Abastante and Lami 2018), subject to a
discussion from the Municipality of Brussels. The decision-making relevance (of the
method) is medium; the stakeholders are supported in constructing numerical scales
basing on qualitative comparisons in terms of differences of attractiveness overcoming the difficulty of representing personal preferences using numbers (Bana e Costa
and Chargas 2004). Accordingly, the method has the ability to inspire discussion and
thoughts rather than providing optimal answers to a problem. The advantage provided by the constant consistency checks of the relative ambiguity of possible
answers can become a double-edge sword if applied in real-time focus groups. In
fact, the risk is to extend too much the available time of the discussion, which is a
huge problem mainly with political stakeholders. The sustainability relevance (of the
case study) is medium. The physical and social fragmentation of cities is at the core
of huge international sustainability discussion. Helping solving this issue will
contribute to reduce the social exclusion, the growth of violence and the loss of
social identity through more transparent and sensible decision processes.
The fourth case study concerns the application of the PROMETHEE method for
the evaluation of alternative strategies for the creation of a Net Zero Energy District
(NZED) in Turin (Becchio et al. 2017). As far as the decision-making relevance is
concerned, the PROMETHEE method proved to be easy and reliable for the DMs
who are able to understand the method itself and the concepts involved since they are
represented by meaningful parameters, such as physical units and economic values.
Furthermore, PROMETHEE method supports multi-actors and group decisionmaking, and it provides a useful tool for debate and consensus building. With
reference to the sustainability relevance, the case study is interesting as the attention
towards the urban scale in energy planning requires the consideration of the full
range of aspects involved (i.e. environmental, economic and social dimensions).
The fifth case study is related adaptive reuse for cultural and art purposes of
underused sites and buildings located in Turin, Italy (Costa et al. 2019). The
decision-making relevance (of the method) is extreme since the DM is involved in
the definition of the categories, in the selection of the actions and the reference
actions, in the identification of the criteria and the criteria scale construction, in
assigning criteria weights and in the identification of possible criteria interactions. It
is a real co-constructive procedure for the whole process. The sustainability relevance (of the case study) is high, because the adaptive reuse of the abandoned
building is a crucial aspect in order to avoid the environmental costs of the construction of new buildings and the urban sprawl.
In the sixth case study the decision-making relevance is high as the application is
related to the development of the NAROR method for supporting the management of
a real estate portfolio (Bottero et al. 2016). In this case, the DMs give preference
information in a very simple way by comparing alternative or criteria from which to
elicit parameters compatible with these preferences. As far as the sustainability
