Abstract
Purpose The causes of high-speed railway failures are complex, and it is difficult to quantitatively and accurately describe safety evaluation. The purpose of this paper is to construct a model to ensure the safety of high-speed railway operations. Design/methodology/approach The authors construct a high-speed railway operation safety evaluation index system from four aspects: personnel, equipment, environment and management and analyze the inter-coupling relationship of various safety factors. Based on the evaluation index system, the use of network analytic hierarchy process (ANP) and fuzzy comprehensive evaluation will be used to establish a high-speed railway operation safety evaluation model. Findings Through the literature investigation and field investigation, combined with high-speed railway safety key points and system composition, 4 first-level indicators and 17 second-level indicators were selected to construct a high-speed railway operation safety evaluation index system. It can be seen from the results that the personnel management system and the signal and control system have the largest weight. Originality/value On the basis of establishing an evaluation index system, comprehensively considering the internal coupling relationship between evaluation indexes and the fuzziness of high-speed railway operation safety evaluation, high-speed railway uses ANP fuzzy network analysis method to construct high-speed railway operation, and the safety evaluation model has certain advantages and practicability in the case of the relative lack of high-speed railway operation data and fault data.
Highlights
As of the end of 2018, the mileage of China’s high-speed railways that have been built and put into operation reached more than 29,000 km, accounting for more than 66% of the world’s high-speed railway operating mileage
2.1 Evaluation index analysis The factors affecting the safety of high-speed railway operations are analyzed from the four aspects of personnel, equipment, environment and management
Personnel factors refer to the staff of various functional departments such as train depot, locomotive depot, public works depot and electricity depot during the operation of high-speed railway, and include management personnel and technical operators at all levels, as well as passengers of high-speed rail trains
Summary
As of the end of 2018, the mileage of China’s high-speed railways that have been built and put into operation reached more than 29,000 km, accounting for more than 66% of the world’s high-speed railway operating mileage. China’s high-speed railway construction has made world-renowned achievements, it still needs to be improved in terms. © Leyi Cheng, Yinghan Wang and Yichuan Pe.
