Then the hesitant fuzzy elements of three groups of hesitant fuzzy sets will be aggregated, respectively, by HFWA or HFWG operators, which is shown as in Definitions 2 and 3.
Let [h.sub.i] (i = 1, 2, ..., n) be a collection of HFEs and let HFWG: [[THETA].sup.n] [right arrow] [THETA] if
Then the HFWG is called a hesitant fuzzy weighted geometric (HFWG) operator, where w = [([w.sub.1], [w.sub.2], ..., [w.sub.n]).sup.T] is the weight vector of [h.sub.i] (i = 1, 2, ..., n) with [w.sub.i] [member of] [0, 1], i = 1, 2, ..., n, and [[summation].sup.n.sub.i=1] [w.sub.i] = 1.
