Design Alternatives Evaluation of Emergency Bridge by Applying Analytic Network Process (ANP)
用网络层次分析法（ANP）评估应急桥梁设计方案

The paper mainly introduces the basic process that applying Analytic Network Process to design alternatives evaluation of emergency bridge.ANP considers all factors,estimates the relative influence from the factors,values factors with ratio scales from 1 to 9,makes pairwise comparisons on factors and synthesizes to get overall results.An ANP case is conveniently computed by Super Decisions ANP Software.The computed results show that the ANP is suitable to evaluating design alternatives for emergency bridges.
