Research and Comparative Analysis of Index Weighting Technique Based on Entropy Weight Method
According to the research on entropy weight method(EWM),the EWM is divided into two categories:traditional EWM and improved EWM.In order to compare the advantages and disadvan-tages of the traditional EWM and the improved EWM,this paper selects four improved entropy weight methods with high usability:the EWM based on 3-scale AHP,the multi-level EWM,the EWM based on RSR,and standard variation EWM,and constructs the evaluation index system of rural revital-ization in Anhui Province.Combined with the evaluation index data,the index is weighted.The results show that:All the four methods could be applied in the field of rural revitalization evaluation.Based on the collected evaluation index data,standard variation EWM was the optimal method.When the index data is difficult to collect or quantify,EWM based on 3-scale AHP is optimal.
