Analytic hierarchy process method for evaluation and management of large-type bridges

The large-type bridges evaluation and management has a great important to perform corresponding maintenance measures.In the paper, analytic hierarchy process is adopted to the large-type bridges evaluation. The evaluation indexes of the large-type bridges are analyzed firstly, and the discriminant matrix is established by the pairing comparison. Finally, weights of first-class indexes and second-class indexes are calculated by the calculation of discriminant matrices respectively, and a case is applied to testify the feasibility of analytic hierarchy process in the large-type bridges evaluation.
