- Forecast Adjustment in Multicriteria Analysis Using Parameterisable FunctionsPublication . São João, Ricardo; Leoneti, Alexandre; Santos, PauloThis investigation proposes improvements to the TODIM multicriteria decision-support method. A new parametrisation of the TODIM phi function is introduced using techniques common in binary-response statistical models, aiming to increase flexibility and better reflect real decision-maker behaviour. Empirical validation uses preference and weighting data from 20 higher-education students (Leoneti, 2016). Results from the original TODIM are compared with an adapted version (TODIMAdp). Spearman correlation with participants’ initial rankings shows that TODIMAdp performs better on average (0.29 vs. 0.20) and correctly predicts the top-ranked alternative in 50% of cases, compared with 37% for the original method. Assuming MCDM ranking methods can be evaluated by their ability to reproduce initial preferences, the study finds that TODIMAdp’s additional parameters increase modelling flexibility and predictive capacity. The results suggest that further exploration of parameter combinations may strengthen TODIM’s descriptive and forecasting performance in applied multicriteria decision contexts.
- Managing Sustainable Energy Decisions:A Prospect – Theory Perspective Theory PerspectivePublication . Guedes, Pedro; Santos, Paulo; São João, RicardoThe survival of humanity increasingly depends on its own actions. Sustainability is a pressing issue that must be systematically integrated into all decision-making processes. In management, multiple factors often influence the selection of decisions at the expense of more sustainable alternatives. Multi-Criteria Decision Analysis (MCDA) methods are used to objectify, support, and enhance the transparency of complex decisions involving multiple criteria. Research shows that applying MCDA in group decision-making increases satisfaction levels and the perception of fairness. These methods foster group commitment and facilitate negotiation toward a collectively supported solution. This communication aims to contribute to future research by replicating the studies of Leoneti & Gomes (2021). In the field of group multicriteria decision, specifically, it proposes replacing Case 3 — "Selection of the New President of a Company" — with two new case studies whose criteria and alternatives are explicitly related to sustainability (energy production sources). This cases will engage specialists and vocational education students in constructing a value tree, including the selection of criteria, alternatives, and performance descriptors. In both case studies Two case studies concerning energy production sources will be developed, and MCDA models will be applied to select the preferred option.
