Safety Evaluation of Railway Exceptional Dimension Freight Transportation Based on AHP-Grey Correlation Analysis
ZHANG Jieru
Abstract：On the analytical basis of the safety impact factors of railway exceptional dimension freight transportation, the evaluation system is constructed from three layers such as loading reinforcement, line parameters and management level. The AHP method is used to establish the index weight of safety evaluation system of exceptional dimension freight transport, the consistency degree of each transportation scheme and standard transportation scheme is calculated by grey relational analysis method. Finally, the reliability of the model and the algorithm is proved by an example analysis for the safety of exceptional dimension freight of Chengdu to Beijing railway.
