OriginatorYeni, F. B., Özçelik, G.Year2018Sources1Related methods8

IV-CODAS (IVAIF-CODAS — Interval-Valued Atanassov Intuitionistic Fuzzy CODAS) is a ranking multi-criteria decision-making (MCDM) method introduced by Yeni, F. B., Özçelik, G. in 2018. 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

IVAIF-CODAS extends CODAS to handle Interval-Valued Atanassov Intuitionistic Fuzzy (IVAIF) data. DM assessments are expressed as IVAIFNs ([μL,μU],[vL,vU]) using a linguistic scale, then aggregated via IIFWA. The method uses IVAIF Euclidean and Hamming distances from the negative ideal solution. Higher AS score = better alternative. Threshold θ (default 0.02) controls when the Hamming distance refinement is activated.

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.
