Intuitionistic Fuzzy Grey Relational Analysis Sorting Technique

The current ongoing pandemic COVID-19 situation severely impacts the tourism sector. The principal economic component in some of the countries is their tourism sector. So, a proper strategy to recommence the tourism sector needs to be formulated. We chalk out a plan of action while solving multiple criteria sorting (MCS) problem. The dealing of COVID-19 involves hesitancy and uncertainty thus, Atannasov’s intuitionistic fuzzy set is used to model this situation. The paper introduces an intuitionistic fuzzy grey relational analysis sort (IFGRA-sort) technique to strategize the reopening of the tourism industry. The proposed technique successfully solves the tourism industry problem given in Current Issues in Tourism (2021): 1-11, Taylor and Francis.
