改进社会力模型的飞机火灾一体化疏散仿真优化

为改善现有飞机火灾应急疏散研究滑梯处旅客行为分析较少及疏散方案整体性不足等情况,规划出包括舱内狭小空间、应急滑梯以及地面在内的一体化疏散通道。此外引入惶恐系数和集体关系因素对传统社会力模型进行改进,根据问卷调查充分了解人群在机上危险时刻的心理状态从而设置建模参数。用AnyLogic软件对一体化疏散流程进行模拟,分析仿真过程中拥挤点的产生原因及环境影响因素并提出合理方案,从不同风向下应急出口开放数量及人员分拣区位置设置等方面进行优化。所得研究结果完善了机上旅客疏散流程,有利于机场应急预案改进及演练。

Simulation Optimization of Aircraft Fire Integration Evacuation Based on Improved Social Force Model

In order to improve the analysis of passenger behaviors at slides and inadequate integrity of evacuation plans in aircraft fire emergency evacuation studies, an integrated evacuation passage including a small space in the cabin, an emergency slide, and the ground was planned. In addition, the terror coefficient and collective relationship factors are introduced to improve the traditional social power model, and the psychological state of the crowd at the dangerous moment is fully understood according to the questionnaire survey to set the modeling parameters. Use AnyLogic software to simulate the integrated evacuation process, analyze the causes of congestion points and environmental impact factors in the simulation process, and propose a reasonable plan, and optimize it from the number of emergency exit openings to different winds and the location of personnel sorting areas. The obtained research results improve the evacuation process of passengers on board, which is conducive to the improvement of airport emergency plans and drills.
