Assessing the vulnerability of urban housing in the spatial area of Tehran metropolis (Case study: neighborhoods of Tehran's 9th district)

Rapid population growth, lack of resources, and mismanagement have made natural and human hazards more and more a major threat to human societies. This means that neighborhoods and urban areas will become the main source of many potential hazards. The main purpose of this study is to analyze and prioritize the neighborhoods of District 9 of Tehran in terms of residential vulnerability indicators using multi-criteria decision-making techniques. This research is theoretical-applied in terms of descriptive-analytical method and its nature. Therefore, in this study, using Shannon's entropy technique to the indicators (building age, materials used, quality of construction of buildings, floors, block placement status), the study was weighted and using WASPAS models, COPRAS, WSA was used to prioritize the vulnerability indicators of the neighborhoods and finally to achieve a single result in the assessment of the vulnerability of the neighborhoods, the integrated model was used. The results of the consolidated model model show that Fatah Industrial Neighborhoods with a score of 7 and Shahid Dastgheib with a score of (5) in terms of vulnerability in terms of urban housing indicators are at a low level of vulnerability and Imamzadeh Abdullah neighborhoods with Score (3) and Sword with Score (1) are in the average level in terms of housing vulnerability indicators, as well as South Mehrabad, Sar-e-Asiab-e-Mehr and Ostad Moin neighborhoods with a score of (-3) and Dr. Hoshyar neighborhood with a score of (7). -) In terms of housing vulnerability indicators, they are at a high level of vulnerability.
