Research on Railway Emergency Risk Decision-Making Method Based on BDN and Multi-agent

With the continuous improvement of people's living standards, outbound travel is already a part of people's daily life. Railway is one of the most important ways to travel, and its popularity has increased with the development of high-speed railway, but it also accompanied by a variety of emergencies. When these emergencies occur, it will cause property losses, and even casualties, so how to reduce the risk of decision-making and make the best decision in the face of emergencies is a key issue to be concerned. In this paper, the multi-agent theory is used to describe the main body, and Bayesian Decision Network (BDN) is used to express the relationship between decision-making subject, decision-making and decision-making scheme; Then the optimal decision-making scheme set is determined by the multi-attribute decision-making scheme selection method. Finally, the emergency treatment of bullet trains fire on viaduct is taken as an example to prove the feasibility of the emergency decision-making method proposed in this paper.
