Revised Simos Procedure: deck-of-cards rank-based weight elicitation (Figueira & Roy 2002)

Overview

Weight_Subjective (rank-ordered cards with blank cards for gaps). Output typically weight (higher value = preferred).

Strengths

• •Method-specific: Weight_Subjective (rank-ordered cards with blank cards for gaps)
• •Native group-decision support (multi-DM aggregation built into the pipeline)

Limitations

• •Assumes: Domain experts available
• •Assumes: Experts can express consistent comparisons

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 REVISED-SIMOS-specific edge handling. recommendation_metadata.assumptions_to_verify also lists boundary conditions.

Common pitfalls

• •Hatalı: 'REVISED-SIMOS bu varsayımı kontrol etmeden uygulamak'. Doğrusu: Domain experts available
• •Hatalı: 'REVISED-SIMOS bu varsayımı kontrol etmeden uygulamak'. Doğrusu: Experts can express consistent comparisons
• •Hatalı: REVISED-SIMOS'yi 'No experts available → use objective weighting' durumunda kullanmak: recommendation_metadata.not_recommended_when alternatif öneriyor.
• •Hatalı: REVISED-SIMOS'yi 'High inconsistency → discard and re-elicit' durumunda kullanmak: recommendation_metadata.not_recommended_when alternatif öneriyor.

Worked example

1. 1.Adım 1 (F1): Step 1: Order criterion cards by importance; insert blank cards between equally-spaced groups; specify ratio z. Formül: \text{Cards: } C_{(1)}, C_{(2)}, \ldots, C_{(n)};\ \text{blank counts } e_{k};\ z = w_{(n)}/w_{(1)} Anchor: Figueira-Roy 2002, p.318 Sec.3
2. 2.Adım 2 (F2): Step 2: Non-normalised weights k_j based on positions and blank cards. Formül: k_{j} = 1 + (z-1)\cdot \dfrac{u_{j}-1}{u_{n}-1},\quad u_{j} = \sum_{l\le j}(1+e_{l}) Anchor: Figueira-Roy 2002, p.319 Eq.(1)
3. 3.Adım 3 (F3): Step 3: Normalised SIMOS weights w_j = k_j / Σ k_l. Formül: w_{j} = \dfrac{k_{j}}{\sum_{l=1}^{n} k_{l}} Anchor: Figueira-Roy 2002, p.319 Eq.(2)
