Determination of Weights of Concrete Girder Bridge Technical Condition Indicators Based on Least Squares AHP-CRITIC Combination Assignment
In order to obtain the weights of the evaluation index of bridge technical condition in line with the actual situation,the analytic hierarchy process(AHP)method was combined with the CRITIC weighting method,and the AHP-CRITIC combinatorial weighting method based on least squares was used to solve the combined weights.In this method,the 0.1～0.9 scale method was selected to replace the traditional 1～9 scale method to determine the subjective weight of the index,the CRITIC method was used to determine the objective weight of the index,and the Euclidean distance function was introduced to determine the subjective and objective comprehensive evaluation score of the technical condition of the bridge,and finally the ideal combination weight was obtained by reasonable operation by using the least squares method.The results showed that when comparing with the weights determined by other combined weighting methods,the index weights determined by the AHP-CRITIC combination weighting method using least squares were the most similar to those in Evaluation Standard for Technical Condition of Highway Bridges(JTG/T H21-2011).
