Understanding Multi-Criteria Analysis outputs and model accuracy
PROMETHEE-GAIA results combine two complementary outputs that work together to support decision-making. PROMETHEE produces a ranked order of the transport policy alternatives, reflecting how each city's interventions perform across all weighted criteria and stakeholder perspectives. A higher rank indicates a policy that better satisfies the overall set of criteria as valued by the stakeholders involved. The GAIA plane then brings a visual dimension to these rankings, mapping both the policy alternatives and the evaluation criteria onto a two-dimensional graph. On this plane, criteria pointing in similar directions indicate aligned objectives, while criteria pointing in opposite directions reveal trade-offs. Policies positioned close to a criterion's axis perform well on that specific criterion. A decision axis summarizes the overall PROMETHEE ranking direction, helping users quickly identify the most globally preferred alternatives.
Together, these two outputs allow users to:
Rank Alternatives
Compare transport policies based on their overall performance across all criteria and stakeholder groups
Identify Trade-offs
Spot tensions between competing objectives (e.g. cost reduction vs. environmental impact) that cannot be simultaneously optimized
Explore Consensus
Identify areas where different stakeholders' preferences align, supporting more inclusive and robust decision-making
