The object of the study is the functioning of control centers during emergencies. Ukraine has faced large-scale emergency events caused by Russian aggression. The experience of crisis management in emergency events showed the need to find new solutions and improve the activities of emergency management centers at the State Emergency Service of Ukraine and GIS technologies in decision-making support systems. The curent paper has formulated a conceptual model of the work of emergency management centers at the Emergency Service of Ukraine; based on it, their main functions were formed. Identification of risks for objects that carry potential danger was carried out and a block diagram of object risk assessment was developed to improve the work of emergency control centers at the State Emergency Service of Ukraine. An approximate list of software and online resources for the operation of emergency management centers at Emergency Service of Ukraine is provided, which makes it possible to summarize the risks that are present in the given territory, isolate them, and pay special attention to prevent possible consequences from them. Based on the computer software MARPLOT, CAMEO, and ALOHA, an example of response to an emergency event was described. In this case, the weather conditions, physico-chemical parameters of the dangerous substance, and the radii of the danger zones of its distribution and the number of people who need to be evacuated were taken into account. In practice, having this knowledge, a head of the emergency management center at the State Emergency Service of Ukraine will be able to effectively manage people without exposing them to danger, as well as conduct timely evacuation. The use of these programs makes it possible to reduce the time of hazard assessment and visualize them, which creates advantages over the existing methodology of the State Emergency Service of Ukraine in terms of speed of hazard assessment. The results have made it possible to solve the problem of increasing the efficiency of the emergency management centers at the Emergency Service of Ukraine and to create the prerequisites for building a geo-information portal that could combine various methods and techniques on one platform Author Biographies Sergiy Yemelyanenko, Lviv State University of Life Safety PhD, Senior Researcher, Head of Department Department of Organization of Research Activities
