Analysis of Vulnerability and Zoning of Ilam city against air attacks from the perspective of passive defense

Vulnerability can be considered as an inherent defect in the specific dimensions of the urban environment, which is prone to damage due to its biological and physical characteristics or design characteristics. Examining the structures of a city and its micro-zoning of vulnerability From the point of view of passive defense, it is a step towards the future of a safe city. The problem of the present study is the challenge of vulnerability in urban structures from the perspective of passive defense and the expected modeling approach is to identify these infrastructures. The scope of the present study; The city of Ilam is in the center of Ilam province and as a support center for the war and the city is involved in the war. This research is based on the applied purpose and in terms of descriptive-analytical methodology based on the approach of spatial-model studies and indicators were identified in the form of 10 categories and using AHPFUZZY-GIS combined analysis weighting of distance maps for They were designed and standardized using the Inverse Distance Weighting tool. The FUZZY OVERLAY tool in ArcGIS software is used for spatial distribution and defense vulnerability assessment. The results show that in the study of the studied indicators, the index of law enforcement centers and warehouses with weights of 0.116 and 0.113 were identified as the most important indicators in the field of passive defense. In the zoning section of Ilam urban structures, the most sections The danger of attack was in the air attack and they were in a very vulnerable situation: 41.28 warehouses, 84.29, residential centers, 62.38 commercial centers, 35.32 administrative centers, 100 administrative centers, terminals and Health centers, 18/27 religious, 39/28 educational and 33.38 roads in this city.
