Agile Supplier Selection in Sanitation Supply Chain Using Fuzzy VIKOR Method

Regarding the diversified needs of the customers and various products of competitors, the importance of agility in supply chain management becomes more significant. Suppliers should provide materials and essential resources of manufacturers without any lead time. In this research, we used a two-stage method for supplier selection. In the first stage, we used a new Data Envelopment Analysis (DEA) method based on network framework to determine the efficiency of the suppliers. This model considered 4 layers for supply chain of each supplier. At the end of this stage, the better suppliers have been selected for the second stage. In the second stage, after determining the efficient suppliers, we identified several criteria for agility in sanitation supply chain. Due to the uncertainty on the supplier’s data, we used a fuzzy Delphi method and ideas of experts about those criteria have been finalized in 8 criteria. Next step was devoted to prioritization of 5 selected suppliers in sanitation industry based on the final criteria with fuzzy VIKOR.
