Depending on their contribution to creating value and increasing efficiency, hotel enterprises make important investments in information technologies. However, there are various criteria and alternatives in the selection process of the most suitable hotel information system. Moreover, the criteria affect each other in a fuzzy decision-making environment. Hence, two techniques are utilized synergistically in this study. IVIF-DEMATEL is initially performed to obtain the importance degrees of the criteria. Afterward, IVIF-TOPSIS is applied to reach the final rankings. An application is performed considering the case in the Turkish tourism sector, and the alternatives are ranked. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.eninfo:eu-repo/semantics/closedAccessChannel managerDEMATELHotel information systemInterval-valued intuitionistic fuzzy setsTOPSISConference Object1197 AISC381389
