To begin with, the simplification of q-ROF TODIM method is established based on the the Pythagorean fuzzy TODIM method and classic TODIM method, a paradox of the q-ROF TODIM method is also analyzed. Then, the generalized Pythagorean fuzzy TODIM method is built based on the generalized TODIM method. Furthermore, the proposed generalized Pythagorean fuzzy TODIM method is applied to the numerical example to verify the effectiveness of the proposed method. Finally, some comparisons are made between the proposed method and some existed decision making methods, the sensibility analysis of the proposed method are also carried out when parameters changed, and the advantages of proposed method are also analyzed.
