Aggregation of dual hesitant fuzzy heterogenous related information with extended Bonferroni mean and its application to MULTIMOORA

•Considering the heterogenous interrelationship of attributes, we design extended BM.•We modify the MULTIMOORA method for the dual hesitant fuzzy MADM.•This paper propose a DHFEBM-based MULTIMOORA method.•We determine the weights of attributes via the attribute significance of rough set.
