灰色关联度方法的改进及其在城市公路客运枢纽优选中的应用

Optimization of Urban Passenger Transfer Hub Based on Improved Method of Gray Correlation Degree

随着相关研究的不断深入,灰色理论被逐步完善,然而具体过程中仍然存在一定不足,引入矢量理想理论,改进灰关联度优选方法,从矢量角度对城市公路客运枢纽备选方案进行分析评价,通过计算各方案与理想解、负理想解参考向量的欧式距离接近度和空间方向接近度,引入微调因子供决策者根据实际情况进行方案优选,建立城市公路客运枢纽布局综合评价模型.通过实例分析,取得了较好的效果.

A improved gray correlation degree method was proposed referring to the theory of ideal 3D model which was used to analyze the urban passenger transfer terminal from the perspective of vector.By utilizing gray correlation degree method together with the theory of ideal 3D model,the paper analyzes the urban highway passenger transfer hub in the perspective of vector.And calculate the adjacency of the level of euclidean distance direction of every program by the establishment of urban road passenger transfer hub distribution evaluation model.Through building vector similarity degree in distance and direction,the paper presents comprehensive degree of similarity to evaluate the chosen schemes.Jiggle coefficient is introduced for decision-makers to conduct programs.In the end,the method is testified by an example and the result shows the rationality of the new method.
