Abstract
Vital arteries or infrastructures are one of the main foundations and basic frameworks of any society, which includes all the facilities required by that society. In modern life, this need has increased with the rapid dependence on these facilities. The vital arteries determine the survival of urbanization in today's world, and these arteries are used to produce and distribute goods and services in urban units, and the possibility of living in cities depends on the quality and quantity of these arteries; Also related to Canada's definition of social security and emergency preparedness are critical infrastructures, networks, facilities, and related physical and information services that, if discontinued or destroyed, could seriously affect health, safety, security, and the economy as a whole. Types of critical arteries include water supply systems, electricity grids, oil and gas pipelines, sewage and surface water collection, communications and transportation networks. The safety of vital arteries before and after natural crises is essential to prevent the destruction and even delayed performance of the arteries and to carefully examine their safety. Given the interdependence and survival of vital arteries and the nature of integrated management and the creation of an information connection between these arteries, what is clear is that it will be impossible to achieve the safety of vital arteries without the use of integrated management, especially in critical situations. Therefore, the aim of this study is to evaluate integrated management in the safety and increase resilience of vital arteries in the metropolis of Tehran, so that by identifying the strengths of integrated management, it can be effective in implementing this form of management. Implementing integrated management in crisis management in Tehran can be very effective in accelerating activities before, during and after the crisis, as well as preventing rework and repetition of activities and thus wasting time and of course saving costs. Due to the high vulnerability of Tehran city to earthquake crisis, integrated crisis management can be an effective help to improve Tehran city management in crises.
