The paper presents an approach for evaluation of the likelihood of damage to the transportation infrastructure in the context of the terrorist attacks on the example of a number of bridges located in Wrocław (Poland). Assuming that there will be only one bridge destroyed in a given area, in order to determine the probability of damage to one of the objects, there was one of multi-criteria optimi-zation methods used, i.e. the method of Analytical Hierarchy Process (AHP). The main advantage of the analysis carried out was that the accepted hierarchy of decision-making options could be easily explained in a scientifi c manner, not only with reference to personal knowledge, experience, and intuition.

The main objective of this paper is (і) to determinate the energy sector as an important part of the resource economy in conditions of increasing epidemiological risks, and (іі) to present the potential of crisis management instruments to influence and strengthen the energy sector in Ukraine. This study uses expert assessments and monographic methods (for the assessment of crisis-management instruments) graphical methods Practical measures aimed at improving and reshaping the energy sector in Ukraine are defined by means of synthesis and economic analysis; statistical and interstate comparisons are used to analyze the Spanish experience of anti-crisis management measures in the post-COVID energy sector.
The study of the world electricity distribution issue shows its direct connection with the energy production source, including renewable energy use, which increased under the impact of COVID-19. The analysis of developed crisis-management systems provides the basis to propose measures to improve and reshape the energy sector in Ukraine. Thus, the results section represents findings to strengthen the energy sector, supporting crisis-management-system development in Ukraine.
The study is a part of a research cycle on energy-sector development, its management and financing. The proposed measures to improve and reshape the energy sector in Ukraine can be applied to specific energy-sector projects, the optimization of investments in the energy sector, as well as being used for the modeling of complex crisis-management systems of various spheres of the economy.
