Dynamic TOPSIS Evaluation Method Based on Connection Degree
For the purpose of comparing the development level of multiple objects to be evaluated at different times and the overall development level in a certain period of time,dynamic evaluation is required.In order to overcome the shortage of Eu-clidean distance calculation of closeness in traditional TOPSIS,this paper introduces the idea of set-pair analysis connection degree into TOPSIS,uses connection vector distance instead of Euclidean distance to calculate closeness,adds time dimension,and proposes a dynamic TOPSIS evaluation method based on connection degree.This method can not only obtain the evaluation value and the ranking result reflecting the difference degree of the evaluation index value,but also obtain the evaluation value and the ranking result reflecting the increase degree of the evaluation index value,and the comprehensive evaluation value and the ranking result considering the above two situations at the same time.Finally,an empirical analysis of green development level of the Yangtze River Economic Belt is used to verify the effectiveness of the proposed method.
