基于多层次灰色评价法的铁路危险货物办理站运输安全综合评价

摘要

This paper puts forward the multi-level grey evaluation method applied in the railway dangerous goods transport station safety evaluation in view of the fact that the station safety evaluation indexes of railway dangerous goods are many and most of them are qualitative evaluation .Firstly, through the analysis of the influ-ence factors of railway dangerous goods transportation , this paper establishes evaluation index system .At the same time, both AHP and entropy method are combined to calculate the weights in the the determination of weight of each index .Then this paper assesses each index using the gray evaluation principle and obtains the comprehensive evaluation result on this basis .%针对铁路危险货物办理站安全性评价指标多，且多为定性评价，提出将多层次灰色评价法应用于铁路危险货物办理站运输的安全评价中。首先通过对铁路危险货物运输影响因素的分析，建立了评价指标体系。同时在确定各指标的权重中，利用层次分析法和熵权法两者相结合求得权值。然后应用灰色评价原理，对各指标进行评价，并在此基础上得出综合评价结果。
