【摘要】：為了對(duì)橋梁設(shè)計(jì)方案進(jìn)行優(yōu)化選擇,建立了AHP-TOPSIS的橋梁設(shè)計(jì)方案優(yōu)選決策模型。該模型引入逼近理想解解排序法(TOPSIS)對(duì)橋梁設(shè)計(jì)方案進(jìn)行優(yōu)選決策,選取10個(gè)評(píng)價(jià)指標(biāo),采用層次分析法確定指標(biāo)權(quán)重,避免了人為賦予指標(biāo)權(quán)重的主觀影響,提高了指標(biāo)權(quán)重的科學(xué)性和客觀性。運(yùn)用該評(píng)價(jià)模型對(duì)某跨河大橋4個(gè)初選設(shè)計(jì)方案(Y1~Y4)進(jìn)行評(píng)價(jià),計(jì)算出每個(gè)方案綜合優(yōu)越度分別為:62.5%,74.6%,18.1%,64.6%,Y2Y4Y1Y3,因此確定Y2為最優(yōu)方案,將該方案應(yīng)用于橋梁建設(shè),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.
