OriginatorHerrera-Viedma, E., Herrera, F., Chiclana, F.Year2002Sources1

CONSENSUS-REACHING (Consensus Reaching — Iterative aggregation of expert opinions toward group consensus) is a ranking multi-criteria decision-making (MCDM) method introduced by Herrera-Viedma, E., Herrera, F., Chiclana, F. in 2002. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.

Key highlights

  • 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.

Consensus Reaching — Iterative aggregation of expert opinions toward group consensus

Strengths & limitations

Strengths
  • 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.
Limitations
  • Assumes full compensation — a strong score on one criterion can offset a weak score on another.
