Abstract: For the hesitant fuzzy Multi-Attribute Group Decision Making（MAGDM） problem with the input arguments exist interrelationship, a MAGDM model based on Hesitant Fuzzy Maclaurin Symmetric Mean（HFMSM） algorithm is developed, which enables decision maker to choose the appropriate parameters to make decision with their preference. Firstly, the new operations are defined with Archimedean norm. Then, combining the Maclaurin symmetric mean, the HFMSM operator is proposed, which is followed by the discussion of four excellent properties and several special cases of the HFMSM operator. Finally, a hesitant fuzzy MAGDM model is developed on the basis of HFMSM operator, and a practical decision case of cloud computing service provider. The results show that the proposed model is better in reliability and scope of application.
