基于NetLogo平台的室内学生疏散过程仿真研究

为了保证学生在突发事件发生时能够安全迅速的疏散,本文基于多主体仿真平台NetLogo,利用瓦片建立真实教室模型,赋予海龟自主移动能力,对不同出口条件、不同人数的教室内学生疏散过程进行了模拟。计算结果表明,随着学生人数的增加,疏散用时随之增大,双出口条件学生疏散用时较单出口条件可平均节约53.8%,可提高学生的安全逃生概率,并利用计算结果对教室出口条件进行了优化。

Analysis on Indoor Students Evacuation Process based on NetLogo Simulation

Evacuation process of indoor students was simulated in terms of different exit conditions and various students’ number based on the multi-agent simulation platform NetLogo to quickly evacuate under emergency circumstances. The real classroom model was built by tile and the turtles were endowed independent moving abilities in the simulation process. The results showed that the evacuation time became longer with increasing student’s number. The evacuation time of students under double-exit condition can save 53.8% on average compared with that under single-exit condition, which can improve the probability safe escape. The calculation results were used to optimize the exit conditions of the classroom.
