Evaluation of Sustainable Potential Bearing Capacity of Tourism Environment Under Uncertainty: A Multiphase Intuitionistic Fuzzy EDAS Technique Based on Hamming Distance and Logarithmic Distance Measures

The proposal of the “dual carbon” goal is a deep reflection of the inherent requirements for achieving sustainable development, and has become an important constraint and policy direction for the development of all industries and sectors during the 14th Five Year Plan period and even longer. Tourism destinations are important spatial carriers for the tourism industry to achieve the “dual carbon” goals, and the tourism environment is the foundation for the sustainable development of tourism activities and an important prerequisite for the sustainable development of tourism destinations. Therefore, in the context of “dual carbon”, evaluating the current status and future development potential of sustainable carrying capacity of destination tourism environment is of great practical significance for achieving the “dual carbon” goal. The sustainable potential bearing capacity evaluation of tourism environment is a multiple-attribute group decision-making (MAGDM) problem. Recently, the Evaluation based on Distance from Average Solution (EDAS) technique has been employed to manage MAGDM issues. The intuitionistic fuzzy sets (IFSs) are utilized as a tool for portraying uncertain information during the sustainable potential bearing capacity evaluation of tourism environment. In this paper, the intuitionistic fuzzy number EDAS (IFN-EDAS) technique is cultivated to manage the MAGDM based on Hamming distance and Logarithmic distance under IFSs. Finally, a numerical study for sustainable potential bearing capacity evaluation of tourism environment is supplied to validate the proposed technique. The main contributions of this paper are outlined: (1) the EDAS technique has been extended to IFSs based on Hamming distance and Logarithmic distance; (2) the CRITIC technique is utilized to derive weight based on Hamming distance and Logarithmic distance under IFSs. (3) the IFN-EDAS technique based on Hamming distance and Logarithmic distance is founded to manage the MAGDM based on the Hamming distance and Logarithmic distance under IFSs; (4) a numerical study for sustainable potential bearing capacity evaluation of tourism environment and some comparative analysis is supplied to validate the proposed technique.
