A geoinformation system of “the hydrocomplexes of Ukraine” as an important part in supporting managerial decisions

Application of a logical-probabilistic method of failure and fault trees for predicting emergency situations at pressure hydraulic facilities (the case of Kakhovka hydroelectric complex)

“…Pressure hydraulic facilities of hydroelectric complexes are among the most common engineering facilities among complex, major, and unique engineering systems. In many cases, they are both critical infrastructure facilities [9][10][11] and potentially hazardous facilities [10,12]. At the same time, studies concerning both critical infrastructure [9][10][11] and the affiliation of pressure hydraulic facilities to potentially dangerous facilities usually ignore the factor of their interaction within the hydroelectric complex as a system.…”

“…The literature [7,8,10,33] provides examples of studies based on the application of probabilistic methods to analyse and evaluate the reliability and safety of complex man-made facilities. In particular, [7,8] indicate the importance of the scenario approach in assessing the safety of hydraulic facilities and [10] indicates the need to take into account their interaction as part of hydroelectric complexes.…”

In particular, [7,8] indicate the importance of the scenario approach in assessing the safety of hydraulic facilities and [10] indicates the need to take into account their interaction as part of hydroelectric complexes. In [14,15], various problems of reliability and safety of hydraulic facilities are formulated within the framework of the probabilistic approach with the analysis of the factors determining the reliability and safety of hydraulic facilities of different type and purpose.…”

“…Given that predicting an accident at a hydroelectric complex is a "poorly structured" system problem, burdened by various uncertainties (stochastic and epistemological, structural and parametric, etc.) [7,10,14], its solution, in the absence of a significant statistical sample, is a complex and unsolved task. The reason for this is, in particular, that the classical deterministic (dynamic) approach is extremely difficult to apply to the forecasting of accidents at hydraulic facilities.…”

Development and use of a geoinformation system for revealing urban problems

“…Most papers relating to geography, such as [5], set out the possibilities of digital technology in processing and presenting spatial information on natural and social phenomena. This topic is quite popular in Ukraine [6][7][8][9].…”
