为提高铁路的整体运输能力,实现资源利用最大化,采用因子分析与信息熵相结合的方法对铁路运输资源利用状况进行优化分析.在分析铁路运输资源技术经济指标的基础上,采用因子分析法对原始数据进行降维处理,并通过熵权法对主因子进行客观赋值,根据计算得出的综合得分预测2013年的铁路运输资源利用状况.研究结果表明:通过因子分析能使熵计算的数据从13个减少至3个,熵计算以及预测所得的1996-2013年的资源利用率的综合值表明铁路运输资源利用率总体呈提升趋势.
In order to improve the overall transportation capacity of railways and maximize the utilization of resources, this paper uses the method of factor analysis and information entropy to optimize the utilization of railway transportation resources.On the basis of analyzing the technical and economic indexes of railway transportation resources, The original data is reduced dimensionally, and the main factors are objectively assigned by the entropy method, and the utilization of railway transportation resources is predicted based on the comprehensive scores calculated in 2013. The results show that the factor analysis can make the entropy calculation data From 13 to 3, the entropy calculation and the forecast of the resource utilization ratio from 1996 to 2013 show that the utilization rate of railway transportation generally shows an upward trend.
