Overview
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.
- Output
- utility, higher is better
- Data
- Hesitant, uncertainty tuples complete
- Weights
- Needs a weight source
- Size
- 2+ alternatives, 3-10 criteria works best
- Used for
- Probabilistic Hesitant MCDM, MAGDM under epistemic uncertainty, evaluation with mixed beneficial/non-beneficial criteria
Look elsewhere when
- •Crisp data sufficient - use base COPRAS directly
- •All criteria are beneficial (TOPSIS-like methods preferred)
Assumptions to verify
- All PHFE entries satisfy γ_k ∈ [0,1] and Σ p_k ≤ 1
- Criteria correctly partitioned into beneficial and non-beneficial
- Non-beneficial criteria sums s_i^- > 0 (no zero denominators)
Edge cases and pitfalls
Ensure Σ p_k ≤ 1 for all PHFE entries before aggregation.
