Abstract

The invention provides a railway operation risk control method based on an accident cause network. The method comprises the following steps: acquiring a risk cause-effect pair and a risk accident cause-effect pair, constructing a railway accident cause-effect network based on the risk cause-effect pair and the risk accident cause-effect pair, and determining the weight of a connection edge betweennodes in railway accident cause-effect network nodes; calculating the shortest cause path between the risk node and the accident node in the railway accident cause network according to the weight ofthe connection edge between the nodes in the railway accident cause network; and constructing a railway operation risk control model according to the shortest cause path between the risk nodes and theaccident nodes in the railway accident cause network, and solving the railway operation risk control model to obtain the risk nodes or risk factors needing to be eliminated in the railway accident cause network. Key risk factors needing to be removed can be selected according to the help of a risk management and control department, so that a risk management and control scheme is formulated, and railway operation accidents are prevented.

Description

technical field [0001] The invention relates to the technical field of traffic safety control, in particular to a method for controlling the risk of railway operation based on an accident-causing network. Background technique [0002] A large amount of accident data has been accumulated during the operation of the railway, including the accident process and the cause of the accident. By analyzing the occurrence process and causes of different accidents, a weight network including four types of risk factors such as human, machine, environment and management can be constructed. However, the weight in the weight network only represents the number of occurrences, and the traditional shortest path method cannot be used to obtain the maximum possible path leading to the accident. [0003] The causal network of railway accidents is an important method to analyze the causes of railway accidents. However, the construction of accident causation network in the past cannot achieve the ...
