Vies Braves (Sea Swimming Lanes) is a pioneer company in designing, promoting, and revitalizing open water and marine itineraries which are protected by buoys, and dedicated to health, leisure, educational and environmental protection activities. The management team’s strategic priority is the implementation of new Vies Braves in new coastal locations. In this paper, we propose a fuzzy decision-aiding approach, using hesitant linguistic term sets to study the viability of new potential coastal locations. The proposed approach considers main economic, political, environmental and social criteria to find similarities between each new alternative and existing ones.
