Research on Multi-exit Laboratory Safe Evacuation

This technical report investigates the safety of evacuation procedures in university laboratories, addressing the critical issue of student evacuation through multiple exits. Utilizing AnyLogic software, the study simulates a laboratory environment to quantify factors such as safety education, training, and familiarity, which enhance evacuation speed. The report details the development of an optimization scheme aimed at improving exit layouts and widths to balance utilization rates among exits. The findings indicate that increased awareness significantly reduces evacuation time and alleviates congestion at exits. The report also reviews historical data on laboratory accidents in China, highlighting the prevalence of explosions and fires, and discusses existing evacuation models and their limitations. By incorporating psychological attributes into the social force model, the study aims to provide a comprehensive approach to emergency evacuations in indoor settings, particularly in environments with dense obstacles. This research contributes to the formulation of effective evacuation strategies for multi-exit scenarios in university laboratories.
