Models for selecting the marketing promotional modes of new energy vehicles financial leasing with fuzzy number intuitionistic fuzzy information

In this paper, we study on the multiple attribute decision making problems for selecting the marketing promotional modes of new energy vehicles financial leasing with the fuzzy number intuitionistic fuzzy information. We first introduce some operations on the fuzzy number intuitionistic fuzzy sets. To determine the attribute weights, a model based on the information entropy, by which the attribute weights can be determined, is established. We utilize the fuzzy number intuitionistic fuzzy Hamacher weighted geometric (FNIFHWG) operator to aggregate the fuzzy number intuitionistic fuzzy information corresponding to each alternative, and then rank the alternatives and select the most desirable one(s) according to the score function and accuracy function. Finally, to show the effectiveness of the proposed method, we give an example to select the marketing promotional modes of new energy vehicles financial leasing with the fuzzy number intuitionistic fuzzy information.
