Firefighting station are one of the elements of public security in the city.to make them have the supposed role in public security; we should look at different urban facilities in detail and lend the city structure as a whole. Appropriate site selection of firefighting stations is one of the most important obligations of the city planners, which should be carefully planned and implemented. Better site selection is meant to avoid waste of resources in one hand and better capability of the stations on the other hand. In this research, best sites for the construction of new stations and moving of those stations with improper location in Tehran city has been studied. First, conceptual model of the study was defined, then, spatial layers and other information about site selection of the stations collected.in the next session Analytical Hierarchy process used to assign weights to spatial layers. This process was done based on the expert’s views and pair wise compactionmethod. After collection of expert views and in order to avoid wrong views, judgment compatibility amounts were calculated. After accepting of CR values, these weights used in future analyses. Network analysis, one of GIS spatial functions, used to find best routes from fire stations to affected area and service area of each station. Based on the analyses of this section and field checks, gave good attitude in terms of stations functionality. Regarding to the locations of existing stations, new stations proposed using a moving widow on the potential sites map.

METHODS: The present study was applied in terms of purpose and descriptive-analytical in terms of nature and method. The data collection method included the library and survey studies. The technique used in the analysis was also the analytic hierarchy process (AHP) based on the experts’ opinion and a pairwise comparison between the indicators in the geographic information system (GIS). FINDINGS: Combining the layers of population density, land use, communication network, medical centers, distance from industrial centers, and distance from fire stations as well as creating the final map, a suitable area for medical centers was identified. CONCLUSION: The study findings indicated that the distribution pattern of the health centers in Omidiyeh is not in accordance with the principles and criteria of passive defense and the establishment of new urban medical centers using the GIS capabilities in the city can be useful in providing services to citizens.

INTRODUCTION: Pre-crisis planning is one of the important issues facing managers and planners, especially in the field of crisis management. In recent years, the world has faced an increasing number of natural and man-made disasters, such as earthquakes. Moreover, the growing effect of disasters on communities has highlighted the need for efficient and effective emergency logistics operations in this field, and some criteria are provided for decision-making and prioritization of relief centers in crisis situations. METHODS: In the current research, Analytic Network Process (ANP) and PROMETHEE (Preference Ranking Organization Method for Enriching Evaluations) methods were used for analysis and ranking, and construction cost and usage time indicators were considered for the first time. Criteria were also defined and evaluated as layers according to global standards and crisis management criteria in the region. In addition, geographic information systems and experts' opinions were used to evaluate the indicators. FINDINGS: Due to the higher weight value, safety (0.36), usage time (0.24), as well as concentration and coverage level (0.22) received priority for the selection of the most optimal relief sites in crisis situations. Therefore, centers, such as Amini Stadium and Golestan Park, which had a lower performance status in terms of the mentioned indicators, compared to other options, were placed in a lower rank in the final ranking, in comparison with other centers. CONCLUSION: The indicators identified in order of importance were security, time of use, concentration and coverage level, and compatible access. In the end, Takhti Stadium, Saat Park, and Rajaei Stadium received priority for the establishment of relief centers in terms of performance and the weight value of the mentioned indicators in time of crisis.

The selection of a tourism development site involves a complex array of decision criteria that may have interdependence relationships within and between them. This study assessed the possibility of establishing natural tourism development site in Lavasan-e Kuchak Rural District (Tehran province) in Iran by using analytic network process (ANP) in a geographical information system (GIS) environment. ANP and the overlaying process were done on GIS. Using 10 information layers in three main criteria including Site Feature, Infrastructures & Services, and Risk & Sensitive Areas, the land suitability map was produced and reclassified into 5 scored divisions from least suitable to most suitable areas. The results showed that about 15.87 of the area of Lavasan-e Kuchak Rural District is most suitable for establishment of tourism development.
