 | abstract        = Four new interval-valued intuitionistic fuzzy operators are introduced. It is shown for them that they exhibit behaviour similar both to the modal, as well as to the level operators defined over interval-valued intuitionistic fuzzy sets, and for this reason, they are called interval-valued intuitionistic fuzzy modal-level operators. Their basic properties are discussed&lt;br /&gt;
