Investigating the effective consequences on the assets of an urban system in facing scenario-based hazards

Abstract

Urban assets are generated through physical elements in a city as part of critical infrastructure. To ensure a sustainable urban future, innovative businesses and people are also essential urban assets. In the possible occurrence of natural and manborne hazards, architecture, population density, gathering locations, and connected infrastructure systems in cities are efficient. Manmade hazards are accidents caused by people that happen in or close to human settlements. These are things that have a major impact on the quality of life, health status, and even mortality. The consequences of such hazards in the town will have to be analyzed. To this end, causal relationships between a town's assets against man-made and natural hazards have been analyzed using the Fuzzy DEMATEL method. According to the results of this research, physical elements have a more important effect on other assets in cities at risk from man-made hazards than any other factor. In the face of man's hazards, economic activity can be more closely linked to population and physical elements. Physical elements have a higher impact on the population and economic activities when confronted with environmental hazards. Physical elements interact more with population and economic activities. In line with the results, more important than physical elements are population and economic activities. Lastly, it is suggested that the risks of dangerous accidents should be assessed and their consequences determined by taking into account the worst-case scenario.
