OriginatorDaami Remadi, F., Moalla Frikha, H.Year2020Sources1Related methods9

IF-CODAS (TIF-CODAS — Triangular Intuitionistic Fuzzy Group CODAS (TIFN-CODAS)) is a ranking multi-criteria decision-making (MCDM) method introduced by Daami Remadi, F., Moalla Frikha, H. in 2020. 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

if-codas extends CODAS to handle Intuitionistic uncertainty. All arithmetic operations (normalisation, weighting, distance computation) are performed using Intuitionistic Fuzzy Number (IFN: μ, ν; μ+ν ≤ 1) algebra. The final scores are defuzzified via score function S = μ − ν before ranking.

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.
