ship collision accident level prediction method and system based on a Bayesian network

Abstract

The invention discloses a ship collision accident level prediction method and system based on a Bayesian network. According to the method, by constructing a ship collision accident prediction model, grade prediction of ship collision accidents is achieved, from the perspective of data, the law between accident factors is found by deeply mining the relation between the accident factors, an expert knowledge method with too high subjectivity is replaced, and the Bayesian network of the ship collision accidents is established. From the perspective of the method, a ship collision accident prediction model is constructed based on the Bayesian network, the ship collision accident level prediction problem is solved, and the development of the maritime risk theory is promoted. From the perspectiveof application, research results can provide scientific basis for ship navigation command and emergency decision making.

Description

technical field [0001] The invention relates to the technical field of traffic safety prediction, in particular to a Bayesian network-based ship collision accident level prediction method and system. Background technique [0002] my country is a big shipping country in the world, and shipping has important strategic significance to the country. With the development of the maritime transportation industry, the routes are becoming more and more busy, the density of ships is increasing, the ships are becoming larger and more specialized, the speed of ships is increasing, and the navigation environment is becoming more and more complicated, resulting in frequent occurrence of various marine traffic accidents. In the increasingly severe situation of maritime traffic safety, how to ensure safe and efficient ocean transportation has become the focus of attention of countries and maritime departments all over the world. [0003] The statistics of water traffic accidents show that t...

Problems solved by technology

Generally speaking, the research on the consequences of marine ship collision accidents (such as severity, casualties, etc.) is still in its infancy, and has great research potential and space, which needs to be further strengthened and deepened.
