On March 27th, the Hujiang Economics and Management Forum Series (92nd Session) was held in the Intelligent Emergency Management Laboratory on the second floor of the Economics and Management Building of USST. Professor Fang Zhiming from the Department of System Science, gave a lecture entitled Modeling and Optimization of Crowd Behavior under Emergencies. Graduate students from the Business School, majoring in system science, management science and engineering, and public administration, attended the lecture.
Starting from the typical accidents and disasters, natural disasters, public health incidents, and social security incidents that happened in recent years, the lecture focused on the common problems and laws of public security emergencies, introduced the public security triangle model, and its three main parts, namely, emergencies, disaster carriers, and emergency management, and introduced the important role of the research method of system science in each of these parts. In particular, for the crowd, a key factor in the disaster carrier, a path for modeling and optimizing the dynamics of evacuation using Agent and cellular automata methods is presented. The focus is on the method of modeling crowd evacuation dynamics based on cellular automata, and how to couple the role of fire, hazardous material leakage, infectious disease transmission and other emergencies on the harm of people to construct the method of emergency risk analysis, assessment and control. Finally, the direction of the application of system science methods in emergency management problems, including the modeling and optimization of emergency material distribution, emergency management decision-making, analysis of the pattern of emergencies and early warning, and the system analysis and optimization of other disaster-bearing vectors, etc., is foreseen.
