This study addresses the problem of pre-disaster preparedness by determining the optimal locations for a limited number of relief containers. These containers serve as mobile logistics units containing essential supplies such as tents, blankets, water, and hygiene kits for immediate post-disaster use. This research proposes a strategic placement model that distinguishes between candidate locations and demand points, acknowledging that not every demand site is suitable for installation and that a single candidate site may serve multiple demand areas. The decision-making process involves two simultaneous levels: selecting the optimal candidate sites and determining the number of containers to be allocated to each selected site, considering varying physical site capacities. A critical feature of the model is the service radius, which ensures that relief is not only available but also accessible within a specific distance. The proposed approach accounts for both satisfied and unsatisfied demand, aiming to achieve a balanced and efficient distribution of limited resources. The model is applied to a case study in the Avcilar district of Istanbul to demonstrate its effectiveness in enhancing urban disaster resilience and response efficiency.
