【摘要】：為了解決山區(qū)高速公路隧道改擴建方案選取決策困難而又缺乏理論依據(jù)的問題,基于直覺模糊數(shù)的海明距離,結(jié)合TOPSIS方法,增加專家權(quán)向量修正,進而得到處理具有優(yōu)先級別關(guān)系的多屬性問題的決策方法。分析山區(qū)高速公路隧道改擴建的影響因素,建立隧道擴建方案影響指標體系。從依托工程實際出發(fā),邀請指定的專家對指標優(yōu)先級別排序,然后利用已建的數(shù)學(xué)模型實現(xiàn)擴建方案尋優(yōu)。該方法在廈蓉高速公路隧道改擴建施工方案優(yōu)選中得到有效運用,說明該方法實用可行,對隧道改擴建施工方案以及類似工程方案優(yōu)選問題具有重要的指導(dǎo)意義。
[Abstract]:In order to solve the problem of difficult decision making and lack of theoretical basis for the selection of reconstruction and extension scheme of highway tunnel in mountainous area, based on intuitionistic fuzzy number of hamming distance and combined with TOPSIS method, the expert weight vector is modified. Then, a decision method to deal with multi-attribute problems with priority level relationship is obtained. This paper analyzes the influence factors of tunnel reconstruction and extension in mountain expressway, and establishes the influence index system of tunnel expansion scheme. Based on the engineering practice, the designated experts are invited to rank the index priority, and then the expansion scheme is optimized by using the established mathematical model. The method is effectively applied in the optimal selection of tunnel reconstruction and extension construction scheme of Xia-Rong Expressway, which shows that the method is practical and feasible, and has an important guiding significance for the optimal selection of tunnel reconstruction and extension construction schemes and similar projects.
