A safe and effective evacuation route is important for reducing casualties during building fires, and this topic has been a long-term focus of emergency management. Indoor space is a space within one or multiple buildings consisting of architectural components and is the basis of indoor route analyses. Based on indoor space, an indoor network model is designed that considers fire protection design, spatial matching between fire information and the indoor space, and the passability of the indoor space during a fire. Then, an evacuation route selection algorithm that considers hazard and time is proposed. The key features of the route selection algorithm, which include assessing the fire hazards, evacuation time in each indoor space and parallel computing in the route selection algorithm, are subsequently presented. Finally, taking a gymnasium as an example, case modelling and fire information integration are performed to investigate two fire scenarios and the optimal evacuation routes over time are identified in each scenario.

安全有效的疏散路线对于减少建筑物火灾中的人员伤亡非常重要，并且该主题一直是应急管理的长期重点。室内空间是一栋或多栋建筑物内由建筑组成部分组成的空间，是室内路线分析的基础。基于室内空间，设计了一种室内网络模型，该模型考虑了防火设计，火灾信息与室内空间之间的空间匹配以及火灾期间室内空间的可通过性。然后，提出了一种考虑危险性和时间性的疏散路线选择算法。随后介绍了选路算法的关键特征，包括评估火灾隐患，每个室内空间的疏散时间以及选路算法中的并行计算。最后，
