基于DHGF算法的综合管廊出线节点选型研究

Outlet Node Selection of Utility Tunnel Based on DHGF Algorithm

由于综合管廊出线节点的选型大部分依托于设计经验,缺少具体可行的选型方法,利用系统科学法中的四元集成法(DHGF算法)建立综合管廊出线节点的选型模型。首先,利用德尔菲法将管廊出线节点的主观影响因素进行定性,构建评价指标体系;其次,通过层次分析法、灰色关联法和模糊判别法将定性指标进行系统地量化计算,最终确定综合管廊出线节点的选型模型;最后,结合工程应用实例,验证DHGF评价模型在综合管廊出线节点选型中的可靠性及有效性。

The existing outlet node selection of utility tunnel depends on design experience,which does not have specific feasible selection method.As a result,the quadruple integration method(DHGF:Delphi,Hierarchy,Grey and Fuzzy)of system science method is used to establish a selection model for the outlet node of utility tunnel.Firstly,the subjective factors affecting the outlet node selection are characterized by Delphi method,and then the evaluation index system is constructed.Secondly,the qualitative indices are systematically quantified by analytic hierarchy process,grey correlation method and fuzzy discrimination method to determine the outlet node selection model of utility tunnel.Finally,the applicable results verify that the outlet node selection model with DHGF method is reliable and effective.
