SPATIAL ANALYSIS OF DISASTER LOGISTICS IN SLOVENIA: A CASE STUDY OF CELJE AND THE 2023 FLOODS
SPATIAL ANALYSIS OF DISASTER LOGISTICS IN SLOVENIA: A CASE STUDY OF CELJE AND THE 2023 FLOODS

Summary/Abstract: As a result of climate change, the increase in the frequency and intensity of hydrometeorological disasters necessitates a reassessment of traditional disaster management strategies and logistical planning. Slovenia's geographical and hydrogeological structure, combined with the flood disaster that occurred in August 2023, has pushed the limits of the existing civil protection infrastructure. This research presents a spatial analysis of a two-echelon distribution network design for humanitarian aid logistics in the context of Slovenia's multi-hazard profile. The study focuses on the Thiessen Polygons (Voronoi Diagrams) analysis, a direct GIS-based geometric solution method, and validates the results with the Set Covering Problem (SCP), a mathematical optimization model, to ensure network resilience. The report is based on the manual identification of potential logistics depot locations in the Celje region. The resulting geometric service areas were overlaid with flood risk maps to analyze accessibility constraints.
