Schweizer-Sklar T-norm — Power-based parametric t-norm family
TNORM-SCHWEIZER-SKLAR (Schweizer-Sklar T-norm — Power-based parametric t-norm family) is a t-norm multi-criteria decision-making (MCDM) method introduced by Schweizer, B.; Sklar, A. in 1960. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.

When to use it
p=1 (Łukasiewicz) is most commonly used in recent q-ROFS MCDM papers. p<0 → more permissive (closer to min). p>1 → more restrictive. Report for p=-1,0,1 to show sensitivity.
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.
- Results depend on the chosen normalisation, weights, and parameter settings.
