Consistency
Koczkodaj Inconsistency Index: Triad-based pairwise consistency measure
Koczkodaj, W.W. · 1993
Strengths
- •Identifies exact worst triad
- •Does not require eigenvalue computation
- •Scale-invariant
Limitations
- •Only flags worst triad; overall distribution not visible from K alone
Method assistant
Grounded explanations: it explains the method, it does not compute.
Assumptions to verify
- •PCM entries are positive and reciprocal
When not to use
- •Aggregated group PCMs are used (CI/CR more standard in practice)
