The general situation of system composition and safety management of high-speed railway terminal isinvestigated and a comprehensive evaluation index system of operational security is established on the basis ofrailway laws and regulations and previous research results to evaluate the operational security management ofthe high-speed railway terminal objectively and scientifically. Index weight is determined by introducinginterval eigenvalue method (IEM), which aims to reduce the dependence of judgment matrix on consistencytest and improve judgment accuracy. Operational security status of a high-speed railway terminal in northwestChina is analyzed using the traditional model of fuzzy comprehensive evaluation, and a general technique ideaand references for the operational security evaluation of the high-speed railway terminal are provided. IEM isintroduced to determine the weight of each index, overcomes shortcomings of traditional analytic hierarchyprocess (AHP) method, and improves the accuracy and scientificity of the comprehensive evaluation. Riskfactors, such as terrorist attacks, bad weather, and building fires, are intentionally avoided in the selection ofevaluation indicators due to the complexity of risk factors in the operation of high-speed railway passengerstations and limitation of the length of the paper. However, such risk factors should be considered in the followupstudies.
Abstract
The general situation of system composition and safety management of high-speed railway terminal isinvestigated and a comprehensive evaluation index system of operational security is established on the basis ofrailway laws and regulations and previous research results to evaluate the operational security management ofthe high-speed railway terminal objectively and scientifically. Index weight is determined by introducinginterval eigenvalue method (IEM), which aims to reduce the dependence of judgment matrix on consistencytest and improve judgment accuracy. Operational security status of a high-speed railway terminal in northwestChina is analyzed using the traditional model of fuzzy comprehensive evaluation, and a general technique ideaand references for the operational security evaluation of the high-speed railway terminal are provided. IEM isintroduced to determine the weight of each index, overcomes shortcomings of traditional analytic hierarchyprocess (AHP) method, and improves the accuracy and scientificity of the comprehensive evaluation. Riskfactors, such as terrorist attacks, bad weather, and building fires, are intentionally avoided in the selection ofevaluation indicators due to the complexity of risk factors in the operation of high-speed railway passengerstations and limitation of the length of the paper. However, such risk factors should be considered in the followupstudies.
