Abstract

To address the issue of subjectivity or objectivity bias in determining the weights of bridge performance indicators using a single weighting method, this study employs the uncertain analytic hierarchy process (UAHP) and entropy weight method to calculate the subjective and objective weights of evaluation indicators. Furthermore, a game theory model is utilized to obtain the optimal comprehensive weights of the evaluation indicators. The UAHP incorporates interval numbers instead of precise values in judgment matrices to reflect the uncertainty and fuzziness of expert cognition. The entropy weight method uses the correlation matrix of evaluation indicators as the judgment matrix and conducts data standardization to obtain objective weights. The game theory approach minimizes the deviation between the subjective weights from UAHP and the objective weights from the entropy weight method. The effectiveness of this approach is verified by taking the cable sheath damage index of cable-stayed bridges as an example in evaluating the reasonableness of calculating comprehensive indicator rankings using this method.
