In this study, a methodology for locating shelter sites after a disaster is developed.
Currently, in Turkey, Turkish Red Crescent is responsible for selecting the location of
shelter areas. First, they identify the candidate shelter site locations. Then, they rank
those locations by using a weighted average function composed of eleven criteria and
whenever there is an emergency, they utilize the locations with the highest ranking until
there is enough space to house the affected population. To improve Turkish Red
Crescent’s methodology, a mathematical model that selects the best possible
combination of shelter sites from a set of candidate locations, controls the utilization of
those sites and assigns every district to its closest shelter site is developed. The
mathematical model is implemented with a decision support system. The decision
support system, which is developed in C#, is an ArcGIS extension that uses Gurobi
optimization software. With the decision support system, the user is able to solve the
problem, obtain an initial solution, edit the solution and view the solution on the map
that is generated by ArcGIS. To test the model with a greater data set, a sample data
based on the Asian side of Istanbul is used.
