This paper addresses the examination of urban resilience to mitigate the life and financial impacts of natural disasters. One of the fundamental principles of urban resilience is the enhancement of infrastructure resilience during natural disasters and incidents. In this regard, a crucial step is improving the resilience of key urban centers. This research employs a combined method of the analytic Hierarchy Process (AHP) and TOPSIS to measure the resilience of flood-vulnerable buildings. Using a descriptive-analytical approach, the paper initially gathers the required data and information, identifies the influential criteria and sub-criteria for ranking the resilience of buildings against floods, calculates the final weights for each of the vulnerable city's key centers, and ranks the options using the TOPSIS method. The ranking results for the vulnerable centers in Hamedan city against floods indicate that, in order, the Industrial University with a weight of 1.000, Payam Noor University with 0.520, Amir Hotel with 0.297, Architecture and Art University with 0.273, and the Blood Transfusion Center with 0.153 are the key vulnerable buildings. The Blood Transfusion Center exhibits the lowest level of resilience, while the Industrial University shows the highest level of resilience. The method used in this research can be extended to all of the cities based on their unique decision-making criteria.
