Probabilistic Hesitant extension of COPRAS
PHF-COPRAS (Probabilistic Hesitant extension of COPRAS) is a ranking multi-criteria decision-making (MCDM) method introduced by Song, H. F. Chen, Z. C. in 2021. 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
PHF-COPRAS extends COPRAS to handle Probabilistic Hesitant uncertainty. Criteria are split into beneficial and non-beneficial groups; weighted PHFE sums are computed, defuzzified via E[PHFE]=Σγ_k p_k, and aggregated using the COPRAS utility formula Q_i.
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.
