An integrated decision making model for sustainable supplier selection under uncertain environment

Sustainable supply chain management has gained extensive attention of both scholars and practitioners in recent years. Due to a rather limited number of literatures considering social responsibility in the evaluation of sustainable supplier, we construct a novel criteria framework based on the Triple Bottom Line theory and then propose an integrated decision making model for supplier selection. We use the DEMATEL method together with ANP to find the criteria weights. Further on, an extended fuzzy VIKOR method is adopted to optimize the ranking of alternatives under the uncertain environment. A case study in the manufacturing industry is presented to demonstrate and verify the effectiveness of the proposed approach. The results shows that the integrated method we proposed is more reasonable to deal with the hybrid data in the uncertain environment than the traditional TOPSIS method.
