基于熵权和模糊积分的城市轨道交通融资方案评价

摘要

提出一种基于熵权和模糊积分综合评价方法, 从融资环境、融资风险、融资成本、建设时间4个主要影响因素去评价城市轨道交通项目融资方案.首先运用三角模糊数将定性指标定量化, 引入政府风险态度因子, 利用熵权法计算模糊测度;最后考虑因素间的非线性关系及交叉作用, 选择模糊积分对融资方案进行综合评价, 为政府决策提供意见.%This paper evaluated urban rail transit project financing options from four main factors, financing environment, financing risks, financing costs, construction time. First, use the triangular fuzzy number of quantitative and qualitative indicators to take the attitude of government risk into account, using the method of fuzzy entropy measure; finally considering the nonlinear relationship between the factors and the role of selecting fuzzy integral to evaluate of the financing scheme, to provide advice for the government decision.
