根据专家对于方案评判指标重要性的自然思维对比过程和形成数据的特点,提出了云化双重AHP模型对备选方案进行选优,并应用于地铁施工方案选择.专家的自然思维对比过程分两次进行.第一次是赖于工程背景,不同施工方案之间相同评判指标的比较;第二次是不考虑实际工程背景下的各指标比较.使用云模型嵌入AHP是为了对专家提供的不确定信息进行处理.基于上述两点考虑构建了云化双重AHP模型.分析了4种隧道施工方案,得到了方案选优指标.分析结果表明:对于给定的工程背景,使用盾构法施工是最优的.最后将该模型与现有4种模型进行对比,说明了模型的相对优点.
According to the experts’ comparison of natural thinking process and the characteristics of forming data, this paper proposed a dual-AHP model of cloud computing to optimize the alternatives and apply them to the selection of metro construction projects.The expert’s natural thinking process is divided into two parts The first time is based on the project background, different construction program comparison between the same evaluation indicators; the second is not considering the actual project background comparison of the indicators.Using the cloud model embedded in the AHP is to provide experts do not Determine the information to deal with.Based on the above two points to consider the formation of a cloud of dual AHP model.Three kinds of tunnel construction program is analyzed and the program selection index is obtained.The analysis results show that for a given engineering background, Optimal.Finally, the model is compared with the four existing models to illustrate the relative merits of the model.
