摘要

Today in the global market, sustainable supply chain management has turned into a significant issue for managers and researchers. Selection and evaluation related to the rewarding and satisfying supplier are one of the main points in each supply chain. Data envelopment analysis (DEA) is a popular method to measure the performance and efficiency of suppliers and organizations. In this study, a novel two-stage DEA network model is proposed in the presence of uncontrollable inputs and undesirable outputs with considering the set of intermediate elements between two stages to evaluate and select the best sustainable supplier. The provided model is applied in a plastic case study by ten decision-making units (DMUs) as suppliers or alternatives to denote validity and applicability of the suggested model.
