Review of Risk Evolution Research and Its Application and Discussion in Rail Transit
Risk connotation analysis and risk evolution mechanism are currently hot issues in risk management research.In this study,the bibliometric method and content analysis were adopted to construct a co-occurrence network diagram of risk evolution at home and abroad,and the research characteristics and distribution of hot topics in risk evolution were comprehensively analyzed.The result shows that risk evolution mainly focused on four hot topics:risk analysis and safety assessment based on graph theory,risk assessment based on system theory,risk prediction and failure analysis based on machine learning,and risk transmission and fault analysis based on simulation and modeling.The risk management framework was constructed,and the risk evolution methodology was systematically analyzed and proposed.The risk evolution research method was elaborated from five aspects:system theory,causal logic,graph theory,modeling and simulation,and machine learning.Finally,the problems and challenges of the current risk evolution in rail transit were analyzed,and the future research trend was explored.The study can provide an academic reference for the construction of risk prevention and control theory systems and technology application practice in safety production.
