The process of urban development has intensified in recent decades, and adaptation of the built environment and critical infrastructures are needed to increase their resilience. Some of the most important of these elements are transportation infrastructures, which is particularly important to address the resilience of these infrastructures as a strategic approach. Therefore, in this research, the resilience of the transportation infrastructures of two (region 9), four (6) and five (region 1) neighborhoods of Tehran metropolis were explained. For this purpose, 6 indicators of population density, texture of localities, design pattern of localities, Placement on the fault, enclosure, width of passage using network analysis method (ANP) in order to evaluate the resilience of transportation infrastructure the locations were weighted and classified. The results of this research showed that the resilience of transportation infrastructure in Kashank neighborhood got the highest score (4.89) and South Mehrabad neighborhood got the lowest score (2.92) in the total of indicators, which indicates better desirability and resilience. The transportation infrastructure of Kashank neighborhood is better compared to other neighborhoods, and in contrast, it is necessary to pay more attention to the transportation infrastructure of South Mehrabad neighborhood and empower them.

In construction of main urban infrastructures, observing the principles of passive defense in order to maintain safety and reduce vulnerabilities in critical situations is very important. In this study, critical infrastructures were identified and ranked. Finally, the most effective and impressible infrastructures for successful management in non-operating defense were identified.

In this study, urban infrastructures evaluated and ranked in relation to each other. Initially, 32 urban infrastructures were identified and introduced in the case study of Guilan province. Then, using the Friedman method, unimportant infrastructure was removed.Finally, most effective and impressible infrastructures of the remaining 23 infrastructures were measured by fuzzy DEMTEL technique.

The infrastructure of the power plant has the least influense on other infrastructures, and the infrastructure of transmission lines and pressure boosting stations has the least influense. Also, airports within urban areas recive the most impact and air and ground cabling infrastructure recive the least impact from others.

Power plant infrastructure is the most effective infrastructure that needs to be rebuilt or re-engineered according to the principles of passive defense due to the time it takes to repair and the high cost of repairing it in times of crisis as well as it is need for other infrastructures.

today tourism is one of hope Bkhsh activities as a development pathway called. In this regard, according to the features, facilities, services and capabilities that are needed for urban tourists, it is necessary to provide for proper planning it can be applied to a greater number of tourists attracted. The harmony between the number of tourists and tourism areas, especially infrastructure capacity must be considered. The criteria for determining the center of tourist areas and determine the infrastructure requirements and is adjusted for inequalities between regions. The goal of this study, ranking the city of the province of sub-structures of tourism. Methodology This study is based on a "descriptive analytical" approach of the space research, applied. In this regard, Zanjan city eijruod (0.417) khodabndeh (.326) are the least infrastructure for tourism. The city of Mahneshan (.287) and Tarom (.245) despite the considerable tourist attractions, but at least Habrkhvrdarnd infrastructure. In the city of Zanjan (0.061), Khoramdeh (.155) and Abhar (0.235) in terms of tourism infrastructure and favorable conditions are favorable for tourism. The province ranks first in the ranking of tourism infrastructure to third account. Over the past half-century tourism has taken a large scale and every year the number of passengers that travel with different motivations, added. According to the World Tourism Organization estimates, nearly 25 million people of tourists in the world in 1950 and in 2000 was about 700 million, the figure in 2020 to about 1.6 billion. These figures represent growth of 7 percent in a 50-year period (2000-1950) is. Thus, according to statistics and reports can be said, the tourism industry has become the largest and most profitable industry in the global dimension, so that 11 percent of the gross domestic product, 10 percent of employment, 5% of exports and 5% the global investment is allocated. So today tourism is one of hope Bkhshtryn activities as a development pathway called. this regard, according to the features, facilities, services and capabilities that are needed for urban tourists, it is necessary to provide for proper planning it can be applied to a greater number of tourists attracted.
