Map displaying the results of the proposed multi-objective two-stage stochastic optimization model for the case study in Banteay Meanchey. It highlights the selected locations for each facility type, including warehouses, shelters, staging areas, and local markets, based on the model’s optimized decisions.The map shows the spatial distribution of victim zones, staging areas, shelters, local markets, local warehouses, non-governmental organisation sites, and a main warehouse across 46 numbered administrative zones in Banteay Meanchey province. Symbols for each category are identified in the legend on the top left. Victim zones, marked with star-shaped icons, appear densely scattered across all zones, especially in zones 6 to 10, 17, 18, 33, and 43. Shelters and staging areas appear mostly in southern and central zones such as 7, 8, 9, 12, 17, and 36. A cluster of service points including a local warehouse, non-governmental organisation site, and local market is visible in zone 33. A large heart symbol is placed on zone 2 of Phnom Penh City, shown in an inset to the right, with another inset below marking Banteay Meanchey's location within Cambodia. A compass and scale bar at the bottom left indicate orientation and a distance of 10 and 20 kilometres.
