• Hesitant fuzzy sets
• Multi-attribute decision making

Purpose - The purpose of this paper is to extend the PROMETHEE method under typical hesitant fuzzy information for solving multi-attribute decision-making problem in which there is hesitancy among experts.
Design/methodology/approach - Different aggregation and distance functions were developed to deal with HFS. But it is rational that different operators applying in existing methods can produce different results. Also, it is difficult for decision makers to select suitable operators. To address the drawback, this paper develops the PROMETHEE method as an outranking approach to accommodate hesitant fuzzy information. Since the proposed method is constructed on the basis of the pair-wise comparisons, it is independent of the aggregation and distance functions.
Findings - To demonstrate the efficiency and accuracy of the proposed method, the authors provide a numerical example and a comparative analysis. The results indicate that outranking-based methods suggest a better ranking than the aggregation-and distance-based methods.
Research limitations/implications - The proposed approach does not consider the hesitant fuzzy linguistic information decision-making problem. Practical implications - The proposed approach can be applied in many group decision-making problems in which there is hesitancy among experts.
Originality/value - This paper proposes an extension on PROMETHEE method under hesitant fuzzy information, which has not been reported in the existing academic literature.
