The fishbone diagram is a diagram that will cause many reasons for a certain result in a systematic way, that is, to express the relationship between the result (characteristic) and the cause (factor) in a diagram. It is a causal analysis method. The fishbone diagram is used in safety analysis. The disadvantage in the field is that it cannot reflect the development process of events
[0004] Therefore, the existing analysis methods of urban rail transit risk accidents based on accident trees and fishbone diagrams lack integrity and systemicity.

Embodiment Construction
[0043] In order to facilitate the understanding of the embodiments of the present invention, the following will take several specific embodiments as examples for further explanation and description in conjunction with the accompanying drawings, and each embodiment does not constitute a limitation to the embodiments of the present invention.
[0044] The method proposed by the embodiments of the present invention starts from basic events (risk points), studies the relationship between risk points, and explores the generation process of risks. There is no obvious superior-subordinate relationship between risk points, and the same risk point may pass through multiple risk chains, and there are also many possibilities for the final risk accident evolved from the transmission of the risk chain. This method is more in line with the law of event development.
[0045] On the basis of determining the urban rail transit risk point set and the risk accident set, the invention studies the ...

The invention provides a multi-layer-network-based method for constructing an urban rail transit risk chain group. The method comprises: determining an urban rail transit risk point and a risk accident type, forming a risk point set by all risk points, and constructing a risk accident set by all risk accident types; according to a multi-layer network theory, defining a connection relationship between the risk points, defining a relationship between all risk points in each layer of network as an internal connection relationship, and defining a connection relationship between the risk points indifferent layers of networks as an external connection relationship; determining logical relationships, including a propagation relationship and a correlation relationship, between the risk points andconnecting all risk points with the propagation relationship; and matching the last risk point in the connected propagation relationship with the risk accident type to form a risk chain group. According to the invention, the risk accident occurrence process can be controlled globally; and corresponding control measures can be taken to reduce the occurrence of the risk accident based on the globalcontrol.
Description
technical field [0001] The invention relates to the technical field of rail transit safety assurance, in particular to a method for constructing a risk chain group of urban rail transit based on a multi-layer network. Background technique [0002] The occurrence of risk accidents in the urban rail transit system is often not caused by the occurrence of hidden dangers at a single risk point, and the occurrence of a risk accident is often caused by the interaction of multiple risk points after the occurrence of hidden dangers. It is particularly important to comprehensively grasp the safety guarantee of the rail transit system by analyzing the interaction relationship, analyzing the generation process of urban rail transit risk accidents, and comprehensively grasping the causes and development process of risk accidents. [0003] Accident tree is a relatively common method for analyzing accidents. The analysis process starts from a single top event, and then analyzes the subord...
