Abstract—The process of fire stations site selection is always traditionally based on the experience of a few people in some special organizations or with regard to available facilities in cities. On the other hand, the proper distribution of fire stations is essential in order to provide relief to vulnerable areas in times of crisis. In the meantime, the correct, accurate and scientific site selection of the fire stations will be an important step in improving the relief operation during the crisis. In this research, a hybrid model has been developed based on Network Analysis and Set Covering Location Problem (SCLP) for the site selection of fire stations in Tehran, Iran. At first, the areas that are covered by the 3-minute standard time of 112 existing fire stations were found on Tehran road network. Then the operational areas of the fire stations were divided into 308 sub-areas and the centers of these areas were considered as demand points in order to respond within the 3-minute standard. By examining the coverage matrix for 112 fire stations, 86% of the areas were covered by standard relief time. By solving the scenario, 29 sub-areas were designed to achieve 100% coverage of sub-areas.
