Abstract
Selecting the most suitable green supplier is one of the main issues for companies. In this paper, an interval-valued hesitant fuzzy ranking method is proposed to rank the green suppliers candidates under conflicted criteria. Hence, the weight of each expert is obtained by extended entropy method based on interval-valued hesitant fuzzy set (IVHFS) approach. In addition, the criteria weights are determined based on preference judgments of experts and the effect of experts' weights. Considering the IVHFS allows the experts to determine some interval-values membership degrees for each green supplier under a set and also applying the criteria and experts weights could lead to a precise approach. Finally, an illustrative example of the green supplier selection is provided to show the validity and applicability of the proposed method.
