【摘要】:为了对桥梁设计方案进行优化选择,建立了AHP-TOPSIS的桥梁设计方案优选决策模型。该模型引入逼近理想解解排序法(TOPSIS)对桥梁设计方案进行优选决策,选取10个评价指标,采用层次分析法确定指标权重,避免了人为赋予指标权重的主观影响,提高了指标权重的科学性和客观性。运用该评价模型对某跨河大桥4个初选设计方案(Y1~Y4)进行评价,计算出每个方案综合优越度分别为:62.5%,74.6%,18.1%,64.6%,Y2Y4Y1Y3,因此确定Y2为最优方案,将该方案应用于桥梁建设,取得了良好效果。
[Abstract]:In order to optimize the selection of bridge design scheme, the optimal selection decision model of bridge design scheme based on AHP-TOPSIS is established. In this model, the approximate ideal solution sequencing method (TOPSIS) is introduced to select the bridge design scheme, 10 evaluation indexes are selected, and the AHP method is used to determine the index weight, which avoids the subjective influence of artificial index weight. The index weight is more scientific and objective. The evaluation model was used to evaluate the four primary design schemes (Y1~Y4) of a cross-river bridge, and the comprehensive superiority of each scheme was calculated as follows: 62.5 and 74.6and 18.1and 64.6respectively, and Y2Y4Y1Y3. Therefore, Y2 is considered as the optimal scheme, and the scheme is applied to bridge construction, and good results are obtained.
