Optimizing Coastal School Tsunami Evacuation through Dynamic Logistics and Graph Theory: A Case Study in Cartagena, Chile. Instituto profesional ipg, Chile Current School Emergency Plans (PISE) in Chile rely on standardized risk assessments and static maps to design evacuation protocols. This approach fails to account for real-world logistical constraints critical for vulnerable coastal populations, such as heterogeneous crowds, street capacity, varying topography, and latency times of institutional alert systems. This Work in Progress research proposes a quantitative framework using graph theory and logistics optimization to transition PISE from administrative compliance to dynamic operational management. Evacuation routes are modeled as networks, introducing velocity penalties based on terrain slope and student mobility, constrained by a strict survival window equation. Preliminary results from Cartagena, cross-referenced with official 2025 regional drill data, validate the model: standard drill times are identified as "false positives" achieved under controlled traffic conditions. To resolve this, the project introduces DERA (Delayed Evacuation Routing Algorithm), a software architecture proposing staggered departures to eliminate multicommodity flow bottlenecks, theoretically increasing the arrival rate of students to safety zones within the survival window and significantly reducing the probability of system collapse during real-world evacuation scenarios.
