ABSTRACT
Lots of methods are used for evaluating suppliers, such as Analytic Hierarchy Process (AHP), fuzzy AHP, TOPSIS, Fuzzy TOPSIS, Data Envelopment Analysis (DEA), Analytic Network Process (ANP), fuzzy ANP, Genetic Algorithm (GA) in literature. However, those methods about supplier selection in the supply chain management require extra data and hardly consider the relationship among criteria. The DEMATEL method has been considered one of the best approaches to deal with the importance and causal relationships among the evaluation criteria [21, 23]. It does not need mass data and fits the problem examined in this research. The DEMATEL can find key criteria to improve performance and provide decision-making information in supplier selection in the supply chain management [27, 28].
