Abstract:

Aiming at the multi-attribute decision-making problem in complex fuzzy uncertain environment, a hesitant Pythagorean fuzzy multiple attribute decision making method based on DEMATEL and VIKOR is proposed. First, the attribute weight is determined by the DEMATEL method, and alternatives are ranked by the VIKOR method. Secondly, for the cases where ranking results are inconsistent, the Kendall-W coefficient is used to perform the ex-ante consistency check. Then a combined fuzzy Borda method is proposed. Spearman coefficient is used to perform the ex-post consistency check, and a combined fuzzy Borda method is proposed. Finally, the feasibility and effectiveness of the proposed method are illustrated by an example.

Key words: hesitant Pythagorean fuzzy set, DEMATEL, VIKOR, combined fuzzy Borda
