Abstract
Decision making for rescue and evacuation is critical for disaster response operations not only in open spaces but also in buildings where hazardous situations occur. For infrastructures with large and complex geometric layout, decision making could be facilitated with computer-aided approaches for better accuracy and efficiency. This research aims to respond to fire in buildings. As the operational plan is influenced by various attributes such as geometry and material of building elements, we combined network analysis with Building Information Modeling (BIM) models to facilitate the decision making for response operations. Building geometry is retrieved from the BIM model for graph generation and route finding. Rescue routes based on graph networks for rescuers can be determined depending on actual building layouts and conditions. In this paper, visibility graphs (VG) and medial axis transform (MAT) are evaluated for graph generation. A hybrid method that combines VG and MAT is proposed. Results of using the hybrid method showed encouraging results. Risks based on building materials are to be adapted for network edge costs to enable lowest risk route finding in the future, and the accuracy and efficiency is expected to be improved for in-building rescue and evacuation operations.
