用AHP-Grey模型对城市轨道交通线网规划方案进行评价选优。建立线网规划方案评价的分层指标体系,采用灰色关联分析方法按灰色关联度大小对方案进行排序。通过在实际项目方案评价中的应用,证明灰色关联分析法的实用性和合理性。AHP-Grey法既充分体现了多指标对总目标的重要性程度,又充分利用并挖掘了决策矩阵中的有效信息,是一种简便而适用的方法。
Use AHP-Gray Model to Evaluate and Select Urban Rail Transit Network Planning. Establish a hierarchical index system for evaluating the planning of line network planning, and use the gray relational analysis method to sort the schemes according to the gray relational degree. Through the application in actual project evaluation, the practicality and rationality of gray relational analysis is proved. AHP-Gray method not only fully reflects the importance of multi-indicators to the overall goal, but also makes full use of and obtains the effective information from the decision matrix. It is a simple and applicable method.
