Fuente: WIPO "sustainability" Embodiments optimize sustainability for a real-world system. One such embodiment obtains multiple-criteria decision analysis (MCDA) results and criteria weighting values used to generate the MCDA results. The MCDA results include candidate sustainability techniques for the real-world system. Each of the candidate sustainability techniques is associated with a corresponding sustainability score. Variable(s) are identified from at least one of parameters of the candidate sustainability techniques and the obtained criteria weighting values. Based on the identified variable(s), using a probabilistic model, a simulated results distribution is generated. Each simulated result of the simulated results distribution is associated with simulated value(s) of the variable(s). Based on a comparison of the generated simulated results distribution and the obtained MCDA results, the obtained MCDA results are transformed by modifying a ranking of the candidate sustainability techniques and associated corresponding sustainability scores, thereby optimizing sustainability for the real-world system.
