An Integrated IVIF-DEMATEL and IVIF-TOPSIS Methodology for Hotel Information System Selection

Abstract

The importance of information technologies in hotels has increased more in recent years due to the variety of required processes and the level of competitiveness in the sector. 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.
