Abstract
We present an evacuation network design problem under cost and travel congestion considerations while incorporating worst-case evacuation time for the evacuees. Employing a time-expanded network, we model for effective and controlled evacuation by determining active shelter locations and evacuee routes that can be implemented in the preparedness stage in response to foreseen extreme events, such as hurricanes and flooding. To solve our model, we devise an efficient Benders Decomposition (BD) framework with convergence enhancements for solving large-scale instances while also taking advantage of specific characteristics of the problem. We design and implement an experimental study to test our BD technique and to conduct sensitivity analysis for various parameters and model validation using data from Central Texas.
