PiF-CODAS — Picture extension of CODAS
PIF-CODAS (PiF-CODAS — Picture extension of CODAS) is a ranking multi-criteria decision-making (MCDM) method introduced by Cuong, B. C., Kreinovich, V. in 2013. 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.

When to use it
pif-codas extends Keshavarz Ghorabaee et al. 2016 crisp CODAS to Picture fuzzy uncertainty via Cuong 2013 PiFS. For each alternative, computes Euclidean E_i and Taxicab T_i PiFN distances to a negative-ideal reference, then combines them in a relative-assessment matrix h_ik using a threshold indicator ψ that gates the Taxicab tie-breaker. Higher H_i = Σ_k h_ik is better. The dual-distance design with τ-threshold gives partial-compensation behaviour: when alternatives are Euclidean-close (within τ), the Taxicab metric resolves the tie; otherwise Euclidean dominates.
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.
- Results depend on the chosen normalisation, weights, and parameter settings.
