Thus, the present study aims to locate urban shelters with passive defense approach in district 4 of Tabriz through descriptive-analytical method. Required data are collected through documentary - library studies and field observations. In order to determine the coefficients of importance of the indices, the network analysis technique is used and this criterion coefficients are applied in the overlay environment. Finally, using fuzzy logic and overlaying the information layers, the preferred locations are identified in proportion to the research objective. The results of the research show that several points in district 4 of Tabriz with more demographic density that are close to fire stations, close to health centers, convenient access to the communication network, far from flammable and crisis applications, standard materials in construction, close to military centers and have a suitable slope are relatively safe and suitable land for the construction of sanctuaries.
