DIBR: Defining Interrelationships Between Ranked criteria
Pamučar, D., Žižović, M., Marinković, D., Doljanica, D. · 2021
Overview
Ranked criteria interrelationship weighting (non-pairwise sequential). Output typically weight (higher value = preferred).
Strengths
- •Method-specific: Ranked criteria interrelationship weighting (non-pairwise sequential)
- •Native group-decision support (multi-DM aggregation built into the pipeline)
Limitations
- •Assumes: Domain experts available
- •Assumes: Experts can express consistent comparisons
Method assistant
Grounded explanations: it explains the method, it does not compute.
Assumptions to verify
- •Domain experts available
- •Experts can express consistent comparisons
When not to use
- •No experts available → use objective weighting
- •High inconsistency → discard and re-elicit
Edge cases
- •See F.steps and D.parameters for DIBR-specific edge handling. recommendation_metadata.assumptions_to_verify also lists boundary conditions.
Common pitfalls
- •Hatalı: 'DIBR bu varsayımı kontrol etmeden uygulamak'. Doğrusu: Domain experts available
- •Hatalı: 'DIBR bu varsayımı kontrol etmeden uygulamak'. Doğrusu: Experts can express consistent comparisons
- •Hatalı: DIBR'yi 'No experts available → use objective weighting' durumunda kullanmak: recommendation_metadata.not_recommended_when alternatif öneriyor.

Worked example
- 1.Adım 1 (F1): Step 1: Order criteria C_1 ≻ C_2 ≻ … ≻ C_n. Formül: C_{1}\succeq C_{2}\succeq\cdots\succeq C_{n} Anchor: Krstić-Pamucar 2022, p.4 Sec.3
- 2.Adım 2 (F2): Step 2: Pairwise ratio α_{j,j+1} between adjacent criteria. Formül: \alpha_{j,j+1} = \dfrac{w_{j}}{w_{j+1}} Anchor: Krstić-Pamucar 2022, p.4 Eq.(1)
- 3.Adım 3 (F3): Step 3: Weight propagation w_{j+1} = w_j / α_{j,j+1}; normalise. Formül: w_{j+1} = \dfrac{w_{j}}{\alpha_{j,j+1}},\quad \sum_{j} w_{j} = 1 Anchor: Krstić-Pamucar 2022, p.5 Eqs.(2)-(3)
