基于物元熵权模型的城市轨道交通网络规划综合评价

Comprehensive Evaluation Research of City Rail Transit Network Planning Based on the Model of Matter Element and Entropy Weight

在分析概括城市轨道交通网络规划内涵和特征的基础上,针对现有评价指标体系的不足,设计了城市轨道交通网络规划评价指标体系。根据可拓学中物元模型与关联函数理论,引入信息论中的熵值理论计算权重,从而建立了城市轨道交通网络规划综合评价的物元熵权模型,并将模型应用于城市轨道交通网络规划方案优选。实例验证该模型科学、有效,对指导城市轨道交通网络规划具有广泛的现实意义。

Based on the analysis and summary of urban rail transit network planning on connotation and characteristics, in view of the deficiency of existing evaluation index system, this paper designs a better evaluation index system of urban rail transit network planning. Then according to the Euthenics matter element model and correlation function theory, theory of entropy in information theory is introduced into the calculation of the weights, establishing the comprehensive evaluation matter-element model of urban rail transit network planning based on entropy weights. By Applying this model in urban rail transit network planning, example results show that this model is scientific and effective. And it has a wide range of practical significance for the evaluation of urban rail transit network planning.
