Locating Temporary Shelter Areas after an Earthquake: A Case for Istanbul

In this study, we first analyze the specific dynamics of the shelter site location problem for an application in Turkey and develop a mixed integer linear programming based methodology which incorporates with their requirements of the Turkish Red Cresent and improve their current system. The mathematical model maximizes the minimum weight of open shelter areas while deciding on the location of shelter areas, the assigned population points to each open shelter area and controls the utilization of open shelter areas. We validate the mathematical model by generating a base case scenario using real data on Kartal, Istanbul, Turkey. Also, we perform a sensitivity analysis on the parameters of the mathematical model using the same and discuss our findings. Lastly, to test the performance of the mathematical model, we use a larger dataset based on the Asian side of Istanbul
