Abstract. The issue of supplier selection is an important issue in the company because it will determine the company's ability to ensure the availability of raw materials in production. This study aims to establish a decision-making model for supplier selection which considers many criteria in which there is dependence between criteria. The method used is fuzzy-analytic network process (fuzzy-ANP). The combined fuzzy and ANP methods is used not only to consider dependencies between criteria but also to minimize uncertainty and inaccuracy in the assessment of importance of each criterion. Four major stages used in the decision model, namely the establishment of supplier selection criteria and sub-criteria, the process of determining dependencies among the criteria, the weighting of the criteria/sub-criteria, and the last one is supplier assessment process. The process of weighting the criteria results in two data, criteria weights without dependency and criteria weights with dependency. The process of formation of criteria/sub-criteria and the ratings to generate weights were obtained from the experts from the company where case study was done. Supplier rating process is done through assessment process using the 5 (five) scale rating. The results of rating for each supplier will then be compared. The results of this method is the ranking of suppliers in a certain procurement process. From this research it is known that the method used, fuzzy ANP, is proved to be appropriate considering that there are dependencies among the criteria/ sub-criteria used and the method is useful to minimize uncertainty or inaccuracy in the assessment process. By employing this method, criteria with the highest weight was obtained, that is quality of human resources which affect as much as 6 other criteria, followed by quality of product, supplier’s reputation, price, and delivery method.
