Determination of Index Weights in Suspension Bridge Condition Assessment Based on Group-AHP
摘要
Abstract
To determine the index weights of the condition assessment model for suspension bridges, group Analytic Hierarchy Process (AHP)approach was explored to determine the corresponding index weights.Firstly,the 10 08.384 ~10 88.384 scale method was adopted based on the Weber-Fechner law.Then,the genetic algorithm was used to optimize the consensus of j udgment matrixes.The consensus of j udgment matrixes was significantly improved after optimization.Moreover,the PSO-K-MEANS clustering algo-rithm was used to classify the experts'opinions,and the expert weights were calculated by the peer-to-peer consensus reaching model.In the end,the presented group-AHP method was applied to a suspension bridge assessment model to verify its feasibility and practicability.Compared with the index weights of the code,it was found that the index weights calculated in this paper were more reasonable than those of the code.The presented index weights of suspension bridges are the effective supplement to the current stand-ard,which can provide reference to revise the current standard.关键词
