In this paper, we expand the Hamy mean (HM) operator and dual Hamy mean (DHM) operator with IVIFNs to propose the interval -valued intuitionistic fuzzy Hamy mean (IVIFHM) operator, interval-valued intuitionistic fuzzy weighted Hamy mean (IVIFWHM) operator, interval-valued intuitionistic fuzzy dual Hamy mean (IVIFDHM) operator and interval-valued intuitionistic fuzzy weighted dual Hamy mean (IVIFWDHM) operator. Then the MADM models are designed with IVIFWHM and IVIFWDHM operators. Finally, we gave an example for competiveness evaluation of tourist destination to show the proposed models.
