Determining the appropriate supplier is a crucial strategic consideration in supply chain management. Worst-practice frontier data envelopment analysis (WPF-DEA) model is one of the new models in data envelopment analysis (DEA). In this paper, the concept of imprecise data envelopment analysis (IDEA) approach and dual-role factor is used to develop WPF-DEA model. Then, the proposed model is applied for supplier selection problem. A numerical example demonstrates the application of the proposed model.
