Integration AHP and MOORA for sustainable supplier selection: A case study on bottled water Indonesian industry

Given the growing awareness of the importance of sustainability in business, selecting sustainable suppliers is now an important component of sustainable supply chain management. The purpose of this research is to propose procedures for Analytical Hierarchy Process (AHP) and Multi-Objective Optimization On The Basis Of Ratio Analysis (MOORA) in solving the problem of Sustainable Supplier Selection. 8 criteria and 15 sub-criteria for sustainable supplier selection were identified, and a case study on the Indonesian bottled water industry was conducted. The food safety and halal criteria are one of the criteria and sub-criteria considered in the Sustainable Supplier Selection. The AHP method is proposed for weighting the criteria and sub-criteria, and the MOORA procedure is used to determine the best supplier. According to the study’s findings, Material Suitability produces the most weight, followed by the Halal Certification sub-criteria. Supplier A3 is the first priority to be selected in the supplier assessment, followed by suppliers A1, A2, and A4.
