A Bridge Safety Fuzzy Evaluation Model Based on Game Theory and Harris Hawk Optimization Algorithm
To effectively evaluate the safety performance of a bridge,a evaluation index system consisting of 4 primary indicators and 30 secondary indicators is first established.A mathematical transformation formula is used to eliminate the influence of inconsistent moni-toring data on the evaluation results.Then,a game theory combination weighting model is established to optimize the FAHP method and the entropy weighting method.The Harris Hawk optimization algorithm is then used to optimize the weights and obtain the global optimal solution.Finally,the safety level of the bridge is evaluated by proximity degree ranking.A case analysis shows that the results obtained are consistent with the actual engineering situation.
