The invention provides a method for constructing a risk chain group of a rail transit system based on an infectious disease model, comprising: determining the risk points in the rail transit system, forming a risk network through edge connections according to the relationship between the risk points; and then calculating the initial risk points of the risk points Migration measure and coupling measure between risk points, and then calculate the comprehensive probability of heterogeneous risk transmission according to the initial average infection rate of risk points; on the basis of traditional infectious disease model, combine risk point state migration measure and risk point coupling measure and heterogeneous risk propagation probability, construct a rail transit system risk propagation evolution dynamics model, and use the asynchronous update method to construct a rail transit system risk chain group. The risk chain group obtained by this method can reflect the law of risk propagation and evolution in the rail transit system, and can provide theoretical support for rail transit operation management.
Description
technical field [0001] The invention relates to the technical field of rail transit system risk control and safety analysis, in particular to a method for constructing a rail transit system risk chain group based on an infectious disease model. Background technique [0002] With the expansion of rail transit network operation scale, the difficulty of safety management of rail transit system is increasing. As a complex system, the safety state of the urban rail system conforms to the system theory that "the change of the system state and system behavior mainly depends on the change of the correlation relationship in the system structure". Therefore, combined with the characteristics of rail transit system operation safety management, attention The dynamic process of risk propagation along the relevant relationship paths in rail transit, and this group of propagation paths is called the risk chain group, and then the risk chain groups that have a high possibility of risk propa...
