权重自适应模糊层次分析方法及应用

借鉴了误差反向修正理论和增量式的思想,结合层次分析法固有的优势,提出了具有自适应能力的权重设定层次分析法(adaptive weight setting method,AWS)新方法,使盾构法隧道施工风险识别模型能够利用较少的施工数据,完成进行权重调整,满足了实际隧道施工中风险评估的需求.该方法在上海地铁某区间隧道工程中进行了试用,取得了良好的效果,表明了该方法的有效性和实用性.

Research and application on method of self-adaptive weight setting AHP

The error back propagation theory and incremental method is used, combines with the intrinsic advantages of AHP, proposes a self-adaptive weight setting method (AWS), AWS can adjust the weight of model based on historical data so as to the shield tunnelling risk evaluation model matches with the fact of construction conditions. Finally, the risk evaluation of a shield tunnelling project in shanghai metro is taken for example to demonstrate the feasibility and effectiveness of this algorithm.
