Characteristic Objects METhod

COMET (Characteristic Objects METhod) is a ranking multi-criteria decision-making (MCDM) method introduced by Sałabun, W. in 2015. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.

When to use it

P(x_i) ∈ [0,1]. Higher = better. COMET is provably rank-reversal free — adding/removing alternatives does not change relative rankings of existing alternatives. Tradeoff: requires expert elicitation for CO scores.

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.
