Abstract
Chile's susceptibility to natural catastrophes, encompassing earthquakes, tsunamis, and volcanic activities, is exacerbated by climate change, resulting in heightened occurrences and increased severity of wildfires, floods, landslides, and droughts. Within this context, optimizing logistics planning and routing is critical to ensure timely aid delivery to affected communities. Our study introduces a novel routing model tailored to address unique geographical and disaster-related challenges faced in Chile. Unlike existing approaches, our model integrates comprehensive inventory control and distribution hub placement, optimizing relief supply routes in natural disasters. We propose a mixed integer linear programming (MILP) model to formulate a supply chain network strategically allocating distribution centers, regulating their inventories, and planning for ground and aerial transportation of relief goods. The efficacy of our proposed model is assessed through experimentation using real-world data sourced from various locations in Chile that have experienced natural disasters.
