PROMETHEE I — Preference Ranking Organisation METHod for Enrichment Evaluations I (partial ranking)
PROMETHEE-I (PROMETHEE I — Preference Ranking Organisation METHod for Enrichment Evaluations I (partial ranking)) is a ranking multi-criteria decision-making (MCDM) method introduced by Brans, J. P., Vincke, P., Mareschal, B. in 1986. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.

When to use it
PROMETHEE I produces a partial preorder: A_i outranks A_k (aPb) if φ⁺_i > φ⁺_k AND φ⁻_i < φ⁻_k. A_i and A_k are indifferent (aIb) if φ⁺_i = φ⁺_k AND φ⁻_i = φ⁻_k. Otherwise they are incomparable (aRb). For a complete ranking use PROMETHEE II (net flow φ = φ⁺ − φ⁻).
Strengths & limitations
- Follows a transparent, reproducible computational procedure that can be audited step by step.
- Handles multiple criteria of differing scales and units within a single decision matrix.
- May exhibit rank reversal when alternatives are added to or removed from the set.
