Intuitionistic Fuzzy Decision Field Theory (Hao-Xu-Zhao-Zhang 2017)
IF-DFT (Intuitionistic Fuzzy Decision Field Theory (Hao-Xu-Zhao-Zhang 2017)) is a ranking multi-criteria decision-making (MCDM) method introduced by Hao, Z. N. Xu, Z. S. Zhao, H. Zhang, R. in 2017. 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-DFT ranks alternatives based on performance scores. Higher score = better rank.
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
- May exhibit rank reversal when alternatives are added to or removed from the set.
