Natural disasters that cause loss of life and property in Türkiye occur frequently. It is also very important to quickly deliver the necessary materials and equipment to people affected by these disasters. Therefore, in this study, Last Mile Humanitarian Aid Distribution with Electric Vehicles 0-1 Mixed Integer Mathematical Model is proposed due to the fuel problems that will be experienced during the disaster process. The proposed model calculates routes that minimize the total distance traveled by electric vehicles, while also considering their charging needs and energy consumption. Given the likelihood of power outages post-earthquake, the model prioritizes the use of solarpowered electric vehicle charging stations. 7 earthquakes with magnitudes between 4 and 5 occurred in Kayseri in 2023. In this study, an application was carried out for a possible earthquake close to the magnitude of the earthquakes that occurred in Kayseri in recent years. The application of this proposed model was demonstrated in an example of post-earthquake aid distribution using electric vehicles in Kayseri province. Distance data and consumed energy amounts for the Kayseri province example were entered into the model and solved in the CPLEX program. As a result, 3 identical electric vehicles met the demands and the total distance traveled by Vehicle 1 is 414.3 km, Vehicle 2 is 18 km and Vehicle 3 is 10.8 km. Additionally, the effectiveness of the use of energy-efficient electric vehicles in disaster management was evaluated in the article.
