客运专线引入铁路枢纽客运站选址是一项复杂的工作.针对其特点从需求性、适应性、经济性、环境影响性、运作性5个要素层15个评价指标出发,建立模糊物元模型,并引入熵理论确定各指标的熵权.通过计算各模糊物元与标准模糊物元之间的欧式贴近度值,对各方案进行优劣排序,从而得到最优方案.该评价模型能有效避免评价标准不确定性、主观臆断性带来的影响,从评价结果看,该评价方法具有科学性、合理性.
The introduction of Passenger Dedicated Line into the railway hub terminal site is a complicated task.According to its characteristics, this paper establishes a fuzzy matter-element model based on 15 evaluation indexes of 5 factors including demand, adaptability, economy, environmental impact and operationality , And introduces the entropy theory to determine the entropy of each index.The optimal scheme is obtained by ranking the schemes according to the Euclidean values of each fuzzy element and the standard fuzzy matter element.The evaluation model can be effective Avoid evaluation criteria uncertainty, the impact of subjective assumptions, judging from the evaluation results, the evaluation method is scientific and reasonable.
