Abstract

The aim of this research is to select suppliers using the Analytical Hierarchy Process (AHP) and Complex PRoportional Assessment of Alternatives with Gray Relations (COPRAS-G). The proposed technique for selecting criteria uses Delphi by considering objective and subjective factors. These criteria are then weighted by AHP and then used as the basis for selecting suppliers using COPRAS. The proposed model has been tested in the Indonesian leather industry for practical use. The suggested model can represent the dynamics of decision-making groups in supplier ranking. By using the selection of factors in this suggested model, decision makers can choose more wisely. The accuracy of the criteria set will determine the results of supplier selection. Therefore, to test the validity of the model, a sensitivity test to changes in parameters is used. The proposed method generates an effective outcome because it is not sensitive to parameter changes.
