ELECTRE I — ELimination Et Choix Traduisant la REalité I (kernel / choice)
ELECTRE-I (ELECTRE I — ELimination Et Choix Traduisant la REalité I (kernel / choice)) is a outranking multi-criteria decision-making (MCDM) method introduced by Roy, B. in 1968. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.

When to use it
ELECTRE I produces a choice recommendation (kernel), NOT a complete ranking. The kernel K contains alternatives not dominated by any other. Increase c̄ or decrease d̄ to obtain a smaller, more selective kernel.
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.
