摘要: 提出基于Floyd算法的化工园区有毒气体泄漏人员疏散路径规划,利用高斯烟团模型模拟有毒气体泄漏后在大气中的动态扩散过程,在保证疏散路线安全的条件下,运用Floyd算法计算最优疏散路径。研究给出了一套针对化工园区液氨泄漏事故人员疏散路径选择的优化方案,通过案例研究表明,该模型科学合理,可为化工园区内大多数建筑提供最优疏散路径。

Abstract: In this paper, evacuation path planning of toxic gas leakage in chemical industrial park based on Floyd algorithm is proposed. Gauss smoke mass model is used to simulate the dynamic diffusion process of toxic gas in the atmosphere after the accident. Under the condition of ensuring the safety of evacuation route, Floyd algorithm is used to calculate the optimal evacuation path. This paper presents a set of optimization scheme of evacuation route selection for liquid ammonia leakage accident in chemical industrial park. The case study shows that the model is scientific and reasonable and can provide the optimal evacuation path for most buildings in the chemical industrial park.
