Abstract:

The importance of protecting the environment is increasing day by day due to environmental concerns such as global warming, human toxicity, eutrophication, and water scarcity. For this reason, companies have started to change their production processes to be enviromentally friendly. One of the necessary changes is to supply raw materials and/or products that are less harmful to the environment. Therefore, companies have to procure raw materials and/or products from green suppliers. This study, it is aimed to evaluate green suppliers for a textile industry under the interval-valued intuitionistic fuzzy (IVIF) environment, considering various environmental and economic criteria. AHP and TOPSIS methods are integrated under the IVIF environment to be used in the evaluation process of green suppliers. In the integrated method, the IVIF-AHP method is used to calculate criterion weights and the IVIF-TOPSIS method is used to rank green suppliers. At the end of the study, a sensitivity analysis is conducted to observe the effects of changes in the weights of the criteria in the selection of green suppliers for the textile industry.
