Interval-Valued Intuitionistic Fuzzy CODAS-SORT (sorting via Euclidean+Hamming relative assessment)
IVIF-CODAS-SORT (Interval-Valued Intuitionistic Fuzzy CODAS-SORT (sorting via Euclidean+Hamming relative assessment)) is a sorting multi-criteria decision-making (MCDM) method introduced by Ouhibi, A. 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
IVIF-CODAS-SORT extends crisp CODAS-SORT (Ouhibi & Frikha 2019) and IF-CODAS-SORT (Ouhibi & Frikha 2021) to interval-valued intuitionistic fuzzy uncertainty (Atanassov-Gargov 1989). Profiles delineate ordered classes; the assignment rule combines IVIF Euclidean+Hamming distances via the relative assessment R(a, b) with threshold function ψ.
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.
- Assumes full compensation — a strong score on one criterion can offset a weak score on another.
