At 10:00 am on May 10th, the third phase of the "Engineering Management Forum" series of lectures of School of Economics and Management of Beihang University was successfully held on the Tencent conference platform. In this lecture, Professor Jianjun Wugave usa detailed descriptionof the subway emergency management of several difficult problems.

ProfessorJianjun Wu is deputy director of the State Key Laboratory of Rail Transit Control and Safety, and deputy director of the Transportation Industry Key Laboratory of Integrated Transportation Big Data Application Technology. He is the Distinguished Professor of Changjiang Scholars of the Ministry of Education, the recipient of the National Science Foundation for Distinguished Young Scholars and the National Excellent Doctoral Dissertation, and the New Century Excellent Talents of the Ministry of Education. He is also the executive deputy secretary general of the Society of Management Science and Engineering, deputy director of the Society of Traffic and Transportation Management, executive director of the Chinese Society of Systems Engineering, deputy editor of China Journal of Highway, editorial board member of Frontiers of Engineering Management, Theory and Practice of Systems Engineering, etc. He has published more than 100 papers in PNAS, TR-B and TR series journals, and won 2 first prizes of the Ministry of Education's Natural Science Award.

The subway network is a huge system with high systematisms and complexity. There are many problems in this system, such as the difficulty of coupling passenger flow and vehicle flow, the difficulty of improving system operation efficiency, and the difficulty of improving management and decision-making level. Especially under the influence of various uncertain factors, the number of emergencies increases, which greatly affects passengers' travel and operation decisions. It is urgent to apply the theory and method of system science and carry out theoretical and applied research with new technology. Aiming at several difficult problems in subway emergency management, this report introduces the construction of simulation method and the application of several typical scenarios from the perspective of multi-agent, such as general emergencies and major public health events in subway operation. Combined with the actual application cases, the corresponding system solutions are proposed to provide support for intelligent management, decision-making and application of the subway network.

To be specific, Professor Wu uses a simulation model based on human-vehicle-environment multi-agent interaction to identify and predict emergencies and public health problems in urban subways. From individual modeling to group evolution, a large-scale epidemic prevention and control simulation system of subway network was developed and applied to the control of Beijing and Jinan subway network. The simulation system can track the trajectory of confirmed personnel and confirm the close contacts by identifying the human state parameters, adopting the multi-angle collection method of human characteristics and the dense crowd screening technology. This system can be applied to the intelligent prediction and induction control management of urban rail transit passenger flow under emergency. Taking Jinan City as an example, the number of waiting people and waiting time can be greatly reduced.

Professor Wu showed us some problems that should be paid attention to during the construction and application of the simulation system through practical cases and simple explanations, which benefited us a lot. During the presentation, the participating teachers and students had an in-depth discussion with Professor Wu about some puzzles in the research, and the presentation was successfully concluded in a warm atmosphere.
