Approaches to manage hesitant fuzzy linguistic information based on the cosine distance and similarity measures for HFLTSs and their application in qualitative decision making

作者：

Highlights：

• We introduce a family of novel distance and similarity measures for HFLTSs.

• We develop a cosine-distance-based HFL-TOPSIS method.

• We develop a cosine-distance-based HFL-VIKOR method.

• We use a numerical example to illustrate the proposed methods.
