Application of AHP Based on Entropy Weight for Risk Identification in Bridge Construction

摘要: The evaluations on the same factor from different experts, based AHP, are not identical, and some even far cry, because evaluation may be effected by knowledge, experience emotion of experts. To remedy this shortage, paper established a hierarchical analysis model entropy. In model, entropy value represents uncertainty results. And weight reflects contribution every expert in assessment. Then comprehensive combination weights factors determined, reflecting importance factor. Applying method, risk bridge construction were analyzed, and, conclusion has important significance for correct countermeasures smooth construction.
