不确定型层次分析法在渡槽结构状态评估中的应用

以渡槽结构综合状态为总目标,建立以安全性、耐久性和适用性为子目标的评估模型.采用不确定型层次分析法(AHP)对渡槽结构进行状态评估,首先构造以区间数表示的不确定型判断矩阵,采用最小二乘法计算指标权重,然后根据专家对底层指标的缺损状况给出的扣分值,逐层计算上级从属指标的状态分值,进而确定渡槽的结构状态,从定性或定量的分析给出了渡槽各指标的评估标准.

Application of uncertain type AHP to aqueduct structure condition assessment

With the integrated condition of aqueduct structure as the general goal,an assessment model with the sub-goal of security,durability,suitability is established.The condition of aqueduct is assessed with the uncertain type analytic hierarchy process(AHP).The uncertain judgment matrices in interval number is built firstly;computing the indies weights with the least square method;then based on the defection subtraction score by an expert,stepwise calculating the score of subordination index technical condition;and then the condition state could be obtained.This paper also establishes evaluation standards of each index in qualitative or quantitative analysis.
