The purpose of this paper is to explore the tourism development model based on genetic algorithm and EWM-CRITIC to cope with the situation facing sustainable tourism development. The STD model is constructed to measure the level of sustainable development of tourism by considering the economic income data, environmental status indicators, residents' quality of life parameters and resource accommodation thresholds. In the study, genetic algorithm is used to optimize the model, entropy weight CRITIC (EWM - CRITIC) m…
