| Abstract: | The selection of the bridge type generally depends on the designer's experiences at the present time. It exist some subjectivity and one-sidedness unavoidably. On the basis of the characteristics of multi-factor and fuzziness, fuzzy comprehensive evaluation method in bridge type multi-scheme selection application has been put forward in this paper. The index system of influencing bridge type selection is determined. Application model and procedures of the fuzzy comprehensive evaluation method are introduced... |
