Abstract: The paper was aimed at reflecting the safety management status objectively in a high-speed railway station. A safety evaluation system of high-speed railway station, including 4 criterion layers and corresponding 18 specific indicators, was established on the basis of referring to railway laws, regulations and experts' research results. The weights of indexes were determined by using the IEM. An improved fuzzy comprehensive evaluation model of high-speed railway station was built by taking advantage of Vague sets theory. A corresponding empirical analysis of the operation safety of a high-speed railway station in northwest China was made so as to verify the model. The results of calculation example indicate that both the station equipment level and personnel ability level have great influence on the operation safety of high-speed railway station, and that the model can reflect the objective situation of high-speed railway station accurately and effectively.

Key words: high-speed railway station, operation safety, interval eigenvalue method (IEM) Vague sets, comprehensive evaluation
