The aim of the present study is to determine the suitable areas for establishing Disaster Management Support Bases in the region one of Tehran municipality. For this purpose, at first, 26 factors were classified in 5 groups. Then, Weighted Linear Combination (WLC) was used as Multi Criteria Evaluation modeling by elimination of constraints, standardization by Fuzzy membership functions in byte scale, factor weighting by the AHP (Analytical Hierarchy Process), and site selection by zonal land suitability (ZLS) in GIS environment. The results shows that the eastern part of the study area (Zones 6, 9, and 10) has the least percent of differentiation and area reduction in texture, transportation and compatibility constraints including residential area, road, health & treatment centers, commercial centers, vacant lands, faults, multi-storey buildings, gas lines, aqueducts, gas stations & diplomatic area which shows more accessible area in the eastern part of the area. Also, the eastern part of the study area has a very high suitability average in non-proximity (incompatibility) factors such as faults, multi-storey buildings, aqueducts, power lines, gas stations, metro lines, diplomatic area & earthquake intensity. The result of siting shows 17 zones for disaster management support bases that there are 14 zones in the eastern part of the region. Then, five zones were selected in the study area including zone A with area of 4900 square meter and suitability average of 166, zone C with area of 2700 square meter and suitability average of 164, zone E with area of 3200 square meter and suitability average of 165, zone L with area of 28100 square meter and suitability average of 146 & zone N with area of 2400 square meter and suitability average of 155. Therefore, it is suggested that decision rule and the methodology of current study can be used in other studies of siting of Disaster Management Support Bases.
