T-norm
Hamacher T-norm: Rational parametric t-norm for fuzzy aggregation
Hamacher, H. · 1978
Strengths
- •Most widely used parametric t-norm in IFN MCDM literature
- •Algebraically simple closed-form
- •Einstein as special case
Limitations
- •Requires choosing γ (often set to 1 by default)
Method assistant
Grounded explanations: it explains the method, it does not compute.
Assumptions to verify
- •γ ≥ 0
- •IFN constraint μ+ν ≤ 1 preserved
When not to use
- •Crisp MCDM
