An integrated <scp>user‐system</scp> approach for shelter location and evacuation routing

Disasters are catastrophic events that can severely affect the life conditions of entire communities. Disaster-related issues usually dealt with according to Disaster Operations Management framework, which is composed four phases: mitigation, preparedness, response, and recovery. This work focuses on two crucial operations belonging response phase: shelter location evacuation endangered populations. Specifically, ultimate scope this paper present some applications a scenario-based mixed-integer two-stage linear program integrates different types evacuation, self- (or car-based) supported- bus-based) namely Scenario-Indexed Shelter Location Evacuation Routing (SISLER) model. The SISLER model solved using an off-the-shelf optimization software, whose performance improved through addition valid inequalities added at root node solution tree improve lower bound. Computational results reported for both testbed instances realistic case study (Sioux Falls network). analysis solutions provides useful managerial insights relevant stakeholders working within planning area, such as emergency management practitioners public service providers.
