Cruise hotel sustainable supplier management using a grey-based decision support framework

Abstract

This study aims to explore the performance of suppliers in the tourism and traveling sector. Therefore, we designed a case study in a cruise hotel and developed a team of experts to evaluate the existing suppliers. To rate suppliers, a grey multi-criteria decision-making (G-MCDM) platform is built to encounter the best-performing suppliers. CRITIC (CRiteria Importance Through Inter-criteria Correlation) and CoCoSo (combined compromise solution) methods are used. The results demonstrate that Food suppliers and Interior design maintenance services are selected as the best-performing actors in supply chain while suppliers for chemical cleaning materials are is rated as the worst.
