Over the past years, several MCDA methods have been developed and a significant drawback of using more than one algorithm for a given problem is the potential conflicting ranking that they may yield. This work aims at setting the first steps toward a systematic framework that reconciles different rankings from MCDA methods and returns to the decision maker a unique solution. The proposed method is contextualised within the existing scientific literature and illustrated considering four case studies to select environmentally sustainable solutions. Results show that a ranking agreed by multiple MCDA methods is more reliable than a ranking obtained by one method.enAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/multiple-criteria decision makingsustainable manufacturingconflict rankingalternative occurrencesConference paper2190-3026
