More and more practitioners and scholars have paid much attention in sustainable supply chain management in recent year. Selecting the best suppliers is a significant yet complex decision which requires careful consideration of various performance criteria. Hence, supplier selection is an important issue and has a strategic significance for every company. One of the techniques that can be used for selecting suppliers is data envelopment analysis (DEA). In many real-world applications, data are often stochastic. Inthis paper, we developa fuzzy ranking method based on Wu et al. (2010) method for complete ranking of decision making units.A case study from Azadi et al. (2012) is presented to exhibit the efficacy of the proposed method for sustainable supplier selection problem in a resin production company.
