This study tried to integrate Analytical Hierarchy Process model and Index Overlay logic in GIS to present a model for fire station location planning. A comprehensive GIS-based fire station location study can be the central component for a master plan for the station locations. This plan can show both the efficiency and deficiency of current fire station coverage for a specified travel time and provide a model for future fire station location. The model is applied to the zone of 6 of Tehran. The existed stations are located in the southern part which a large area of the North and North West is out of emergency aid. Also these sites have other location problems as they have access only to one sided road. The results of this research introducing two sites which are most appropriated for the establishing the two new stations. The major advantages of the new proposed sites are: Accessibility to two sided road, setting in the most populated area of the zone and the high potential for interventions.
