Hesitant fuzzy QUALIFLEX approach with a signed distance-based comparison method for multiple criteria decision analysis

作者：

Highlights：

• We propose a novel concept of the hesitancy index for the HFE.

• We introduce two novel hesitant fuzzy distance measures.

• We present a signed distance-based comparison method for HFEs.

• We develop a hesitant fuzzy QUALIFLEX outranking method.

• We modify the hesitant fuzzy ELECTRE method to conduct a comparative study.
