Conducting a comparative analysis of the system state options under various external influences

Abstract

Abstract One of the principles of increasing the sustainability of cities as a part of the campaign “My city is getting ready!” states: “Identification and study of risks, use of scenarios of existing and future risks”. The city is a complex system, “packed” with all kinds of dangers. Dangers affect all elements of this system and it is necessary to identify and monitor processes that contribute to the development of hazards into threats, i.e. conduct research, in this case, “urban risks” and learn to manage them. In our opinion, the “Tree structures” method of risk analysis may be suitable for the study of “urban risks” [14], which allows, in particular, to analyze various but interrelated situations and events in relation to the entire system within a single “tree”.
