This research aims at finding the optimum location of Military Logistic Supply Coordination Centers (LSCC) that are established by Turkish Land Forces for gathering and distributing the logistic supply materials among citizens in an area of a county damaged by a natural disaster, i.e. earthquake. The problem of finding the optimum locations of LSCCs in disaster regions is modeled as a Maximal Covering Location Problem. Coverage distances are defined based on the capacity of LSCCs that can be located within the area of counties in the damaged regions. Then, candidate points representing potential sites and demand points representing the provinces having high expected damage estimation due to a probable future earthquake that may occur at the vicinity of Ankara Metropolitan area, are defined. In order to set the standarts on various issues regarding the selection of candidate points, additional constraints are defined. Furthermore, weights, determined by considering the earthquake damage hazard expected for each region are assigned to the demand points. The seismicity of Ankara has been investigated by using the statistics of earthquakes equal or larger than Magnitude>4 that occurred in a region with a 140 km radius for the time interval 1900-1997. Two different scenarios are developed for this model. Optimal solutions are found using mathematical programming software LINGO. Finally, the changes in the optimal solutions are analyzed by altering the problem parameters.
