摘要/Abstract

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%,Y₂>Y₄>Y₁>Y₃,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, an optimization model of bridge design scheme based on AHP-TOPSIS was established. The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was introduced into the model to optimize the selection of the bridge design scheme. Ten evaluation indicators were selected and the weights of the indicators were determined using Analytical Hierarchy Process (AHP) method to avoid shortcoming that the indicator weights were influenced by the subjectivity of the decision maker. The method improved the scientificalness and objectivity of indicator weights. This model was applied to evaluate four schemes of crossing bridge design. The comprehensive superiorities of the four schemes were calculated as: 62.5%, 74.6%, 18.1% and 64.6%. So the schemes were ranked as Y₂>Y₄>Y₁>Y₃, and scheme Y₂ was the optimal one. Scheme Y₂ was applied to bridge construction and good results were achieved.

Key words: road engineering, bridge design, optimization decision model, technique for order preference by similarity to an ideal solution (TOPSIS), analytic hierarchy process (AHP)
