摘　　要：针对室内应急响应中如何科学、高效地对人员进行个性化实时疏散导航问题进行了研究,构建了一种面向复杂室内环境下融合多种上下文的应急疏散导航位置模型。利用改进的Dijkstra算法,结合实际环境动态上下文计算出实时疏散导航路径,为不同类型用户提供地图导航、语音导航、短信导航等个性化服务,同时为应急指挥者提供辅助决策支持。并以医院为例进行了实验,实验表明基于该模型及算法能够高效计算出满足不同类型用户需求的实时疏散导航路径,可应用于医院、商场等环境的应急疏散导航与救援中。The research focused on how to provide scientific, efficient and personalized real-time evacuation and navigation under indoor emergency response. This paper built an indoor navigation location model that fused a variety of context for emer- gency evacuation. In combination with the actual environment dynamic context, the model used the improved Dijkstra algo- rithm to calculate the real-time evacuation navigation path in order to provide different users with customized services such as map navigation, voice navigation, text message navigation and assistant decision. Experiments were carried out in a hospital. The results show that the model and algorithm can efficiently compute the real-time evacuation navigation path that satisfies dif- ferent types of user needs, and can be applied for emergency evacuation, navigation and rescue under the situations like hospi- tals or department stores.
