- Abstract:
- In the durability evaluation of bridge,certainty factor of index ’s relative importance of differentexperts ’evaluation is related to experts’ research experience.Firstly,according to the similarity theory ofvector,the similarity of the relative importance matrix of different experts is studied to determine experts ’certainty factor in this paper; secondly,using different experts’ indeterminate judgment matrix and randomtheory,the random value in the interval of relative importance index is used to form many judgment matrix,and different weight coefficients are obtained according to the above judgment matrix ; lastly , different experts ’certainty factors and weight coefficients are considered together,weighted average of different experts’ weightcoefficients is the final index weight value. Thus,the subjectivity of different experts is reduced and the evalu-ation conclusion is more credible,the research result showed that the computation accuracy in this paper wasvery high.
