基于模糊层次分析法的工程建设方案比选评估分析

Comparative evaluation and analysis of engineering construction scheme based on fuzzy hierarchical analysis method

以某越江通道项目设计方案比选为背景,分别对桥梁和隧道等工程建设方案进行研究,针对水域两岸及中间岛屿等特殊地形因素,重点关注安全、适用、经济和美观等四大方面指标,并基于模糊层次分析法对各指标因素进行权重计算,由此可以对各工程建设方案进行比选评估,最终得出合理推荐方案。基于本案例,可以得出以下结论:(1)模糊层次分析法相较于传统层次分析法提升了计算效率;(2)层次分析法适用于工程建设方案比选的指标因素权重分配阶段;(3)本文所述越江通道工程建设方案综合评价方法体系对相关类似工程案例具备借鉴参考意义。

Based on the comparison and selection of the design schemes of a river crossing channel project,the project cons truction schemes such as bridges and tunnels are studied respectively.In view of the special topographic factors such as the two bank s of the water area and the middle island,the four indicators of safety,applicability,economy and beauty are focused on,and the wei ght of each indicator factor is calculated based on the fuzzy analytic hierarchy process,so that the project construction schemes can b e compared and evaluated,and the reasonable recommended scheme can be finally obtained.Based on this case,we can draw the fol lowing conclusions:(1)Compared with the traditional analytic hierarchy process,the fuzzy analytic hierarchy process improves the c omputational efficiency;(2)The analytic hierarchy process is applicable to the index factor weight distribution stage of project constr uction scheme comparison and selection;(3)The comprehensive evaluation method system for the construction scheme of the rivercrossing channel project described in this paper has reference significance for similar project cases.
