High-speed rail risk analysis and control method and high-speed rail risk analysis and control system

Abstract

The invention relates to the technical field of risk control, and provides a high-speed rail risk analysis and control method and a high-speed rail risk analysis and control system. The method includes the steps: performing cause analysis and effect analysis for hazardous events of a high-speed rail system by the aid of a fault tree and an event tree respectively, enabling m types of causes and n types of effects to form mXn accident sequences, and obtaining risk values of all the accident sequences; and sequencing all the accident sequences according to the risk values to obtain high-risk accident sequences, setting cause and effect control measures aiming at the high-risk accident sequences, and setting further failure control measures for preventing the cause and effect control measures from failing. The method and the system have the advantages that risk of the hazardous events is comprehensively predicated by means of risk analysis of the accident sequences, and the control measures are set by expanding the causes and the effects of the high-risk accident sequences, so that two elements forming the risk of the hazardous events are controlled respectively, and further the risk of the hazardous events is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of risk control, in particular to a high-speed railway risk analysis and control method and system. Background technique [0002] Risk refers to the possibility of unexpected events, usually measured according to the severity of the consequences of the event and the possibility of the event, if quantitative analysis is used, its mathematical formula is expressed as: R=F*S; where , R represents the risk, F represents the frequency of adverse events, and S represents the severity of the consequences. [0003] According to the risk components and their relationships, the risk analysis and control methods currently used in various industries have made a general definition of the application of risk analysis and control, such as the British comprehensive safety assessment method (Formal Safety Assessment, referred to as FSA) to represent the current typical risk assessment method. In November 2004, Wuhan Univer...
