Presenting an integrated BWM-VIKOR-based approach for selecting suppliers of raw materials in the supply chain with emphasis on agility and exibility criteria (Case study: Saipa corporation)

In this study, in order to select suppliers of raw materials for Saipa Automotive Corporation as one of the largest factories in Iran, environment, exibility, and agility criteria are studied and, then, some sub-criteria are also considered for each criterion. The sub-criteria include green design, clean technology, environmental performance, agility in operational systems, market agility, logistics agility, product exibility, exibility in transportation, and resource exibility. It should be mentioned that the assumed criteria are applied based on the characteristics of the case study. Therefore, the main variables required for the identication of criteria that aect the selection of suppliers are studied with regard to environmental factors within the case study. In order to rank suppliers and select the best ones, the best-worst multi-criteria decision-making method (BWM) and VIKOR approach are used. According to the calculations based on the proposed process in this study and the information about the desired criteria, 7 suppliers are selected as the best ones. Since the approach presented in this study has combined BWM to determine weights and VIKOR method for the nal ranking of options, this approach can be also applied to other studies.
