Development of a Sustainability-Based Supplier Evaluation System in the Service Sector Supply Chain

Corporate S faces challenges in its procurement process, including delayed deliveries, incorrect item specifications, and increased costs that reduce profitability. Its current supplier evaluation system focuses solely on economic aspects, neglecting sustainability. This study aims to design a sustainable supplier evaluation system using the DEMATEL-ANP-VIKOR method, involving economic, social, and environmental criteria. ANP results show that the economic criterion holds the highest weight (0.648), followed by social (0.252) and environmental (0.099). VIKOR analysis (v = 0.5) ranks Supplier 3 as the most suitable, with a Q value of 0.000. Based on data collected in early 2025, this system offers a structured and objective approach to supplier selection, aligning operational efficiency with sustainability goals and the SDGs.
