Sustainable supplier selection based on VIKOR with single-valued neutrosophic sets

Area of Science:

• Operations Research
• Supply Chain Management
• Decision Science

Background:

• Supply chain sustainability is critical due to economic, environmental, and social factors.
• Supplier selection is a key strategic element for organizational competitiveness and sustainability.
• Multi-criteria decision-making (MCDM) with uncertainty complicates sustainable supplier selection.

Purpose of the Study:

• To develop a robust method for sustainable supplier selection under uncertainty.
• To address the challenges of insufficient information and decision-maker subjectivity in MCDM.
• To enhance the consistency and reliability of sustainable supplier evaluations.

Main Methods:

• Application of the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) technique.
• Integration of single-valued neutrosophic sets (SVNS) to handle uncertainty and imprecision.
• Sensitivity and comparative analyses to validate the proposed framework.

Main Results:

• The VIKOR-SVNS method effectively manages fuzzy and uncertain information in supplier selection.
• The approach minimizes the impact of personal biases and factor correlations on evaluation outcomes.
• Demonstrated improved consistency and reliability in selecting high-caliber, sustainable suppliers.

Conclusions:

• The proposed framework offers a valuable tool for MCDM in sustainable supply chain management.
• It provides a systematic approach to selecting suppliers with sustainable business practices.
• The method enhances decision-making transparency and reduces decision-maker regret.
