Research on Correlation Inference of Safety Risks and Accidents in Railway Freight Operations Based on 5M1E
The safety of railway freight transportation,as an essential guarantee for the safety of railway operation,car-go,and passengers,is an important support to ensure the continuous increase of railway freight volume.Aiming at long time consumption and errors in the analysis of the current problems existing in railway freight safety,according to the 5M1E quality management concept,this paper considered the major areas of safety risks during railway freight operation and systematically analyzed the factors affecting railway freight safety.Based on the accident causation chain model con-structed by Bode and Roftus,the accident phenomenon model of railway freight was proposed based on 5M1E.This pa-per further used Apriori algorithm to analyze the correlation between influencing factors,movement status and potential accident risks.Based on the data of freight safety accidents and near-miss events of S railway company from 2017 to 2018,the association rules of railway freight system safety accidents and influencing factors were obtained,providing ref-erence for the precise management and control of railway freight safety risks.Compared with the current risk correlation analysis method of screening,searching and statistics by fields,it can significantly reduce the workload of risk assess-ment for management personnel,and greatly improve the ability to identify and prevent railway freight safety risks.
