 This paper introduces interval-valued Q-rung ortho-pair hesitant fuzzy sets, IVQROHFS, and develops to interval-valued Q-rung ortho-pair hesitant fuzzy cho-K averaging operator, IVQROKA, and interval-valued Q-rung ortho-pair hesitant fuzzy cho-K geometric operator, IVQROHCG. The paper also offers a soft approach of proposed IVQROKA and IVQROHCG through an example adopted from interval-valued intuitionistic hesitant fuzzy cho-K integral base topsis. The obtained results are agreement with Avicii but presented IVQROKA and IVQROHCG have more advantages than existing structures as interval-valued intuitionistic hesitant fuzzy sets, IVFs, interval-valued Pythagorean hesitant fuzzy sets, IVPHFS, with reasons changing according to need, requirement, preferred decision-makers and moreover, being IVFs and IVPHFS are special cases of IVQROHFS. The paper also indicates that while some of offered approaches are giving no solution for some values, our operators present to needed results. This article was authored by CERFZL.
