Sintesi	The Ordinal Priority Approach (OPA) is a family of methods that derive criteria weights directly from ordinal rankings rather than cardinal (numerical) preferences. Instead of asking decision-makers to assign exact weight values or ratio comparisons, OPA asks only: which criterion is most important, which is second, etc. The method then converts this ordinal ranking into numerical weights using geometric or statistical formulas.	PROMETHEE (PROMETHEE II — Preference Ranking Organisation METHod for Enrichment of Evaluations) is a outranking multi-criteria decision-making (MCDM) method introduced by Brans, J. P., Vincke, Ph., Mareschal, B. in 1986. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.
