%X With respect to some drawbacks of the existing interval-valued hesitant fuzzy Hamacher aggregation operators, a group decision-making method is developed on the basis of the improved interval-valued hesitant fuzzy Hamacher weighted aggregation operators. First, after the analysis of the existing interval-valued hesitant fuzzy Hamacher operator cannot satisfy idempotency, some new operational laws for Interval-Valued Hesitant Fuzzy Elements（IVHFEs） are defined. Then, two new improved interval-valued hesitant fuzzy Hamacher aggregation operators are proposed, including the Improved Interval-Valued Hesitant Fuzzy Hamacher Ordered Weighted Averaging（I-IVHFHOWA） operator and the Improved Interval-Valued Hesitant Fuzzy Hamacher Ordered Weighted Geometric（I-IVHFHOWG） operator. Furthermore, the common forms and the relationship among these proposed operators are discussed in detail. Finally, a logistics enterprise selection model is developed with I-IVHFHOWA operator and I-IVHFHOWG operator, and the validity of the model is illustrated by an example.
