Документ Analysis of the dynamics of Europe stock markets development(Fintechalliance LLC, 2023) Serhiienko, Olena; Bril, Mykhailo; Baranova, Valeria; Tatar, Maryna; Bilotserkivskyi, OleksandrThe article proposes a complex of economic and mathematical models of assessment, analysis, and forecasting of the world stock indices development state for effective management of investment flows. The modern concept and strategy of European countries’ stock market development were considered, and the existing methods of diagnosing the stock market development level were analyzed. ARIMA models were built and spectral analysis of the main world indices was carried out. The possible trends in the stock indices development for the future period were analyzed using predictive models. It makes it possible to determine directions for improving the stock market efficiency and investment strategies in modern conditions.The proposed set of models for evaluation, analysis, and forecasting of the world stock indices state can be used to test various trading strategies and to test various hypotheses in relation to the entire stock portfolio of a particular company or to one stock index. The results of the research can be used in the development of theoretical provisions and methodological tools for evaluating the global stock market effectiveness in modern conditions and development trends in local markets.Документ Application of Cost-Effective Acoustic Intelligence to Protect Critical Facilities from Drone Attacks(Institute of Electrical and Electronics Engineers, 2022) Pohasii, Serhii; Baranova, Valeria; Bilotserkivskyi, Oleksandr; Haponenko, Olha; Serhiienko, Olena; Vorobiov, BohdanUnauthorized use of unmanned aerial vehicles (UA Vs) for surveillance of important objects, carrying out terrorist attacks and sabotage, throwing prohibited objects (weapons, drugs) has updated the search for cost-effective and technically feasible solutions to counter UA Vs. An analysis of materials on this topic showed that the effectiveness of defeating all types of UA Vs by existing means of air defense and electronic warfare is quite high. However, the problem of countering small UA Vs, based on the experience of the war in Ukraine, is not resolved. The purpose of the article is to analyze the UA V, as an object of detection and countermeasures, using acoustic means of airspace control with minimal economic costs. The article presents the results of the analysis of the UAVas an object of detection and the issuance of target designations by means of acoustic observation.Документ Applied aspects of proactive modeling of innovative-investment processes of complex hierarchical systems: enterprise–region–state(Ljubljana School of Business, Slovenia, 2020) Sergienko, Olena; Tatar, Maryna; Bilotserkivskyi, Oleksandr; Baranova, ValeriaThe paper proposed a proactive mechanism of innovative activity management of complex hierarchical systems (CHS), consisting of successive stages of assessment, analysis, planning, forecasting and innivative activities regulation at the levels of an enterprise - a region – the state. Specific tasks of the proposed mechanism require model support, in connection with which the author has developed a set of models for the proactive innovation management SYSTEM. The valuation models and analysis of the innovation capacity and innovation outcomes of socio-economic system of a region (SESR), which allow, in contrast to the existing models, to compare the results of innovation activities and innovation potential and to make a conclusion about the effectiveness of the existing potentia use are built. The model of evaluation of innovative projects of business-industrial structures (BIS) efficiency based on the use of fuzzy set theory and methods of multicriteria problems solution, which allow to consider the risks arising at each stage of the innovation life cycle. The set of models of economic evaluation of SESR innovative activities based on panel data, which allows to estimate the resource use efficiency in the implementation of innovative activities and to predict the consequences of managerial decisions on stimulation of innovative activities is proposed. The simulation model scenarios of stimulation of SESR innovative activity, which allowed the simulation of scenarios to stimulate and assess their performance in order to select the best scenario of innovation regional systems according to the criteria of profit maximization, maximizing the number of innovative-active BIS and maximize the gains integrated assessment of SESR innovative activity results are designed. The simulation results allowed to determine the best scenario for promoting regional systems and the state as a whole.Документ Concept of financial flow management of enterprise corporate security system(ТОВ "Фінтехальянс", 2022) Sergienko, O.; Volosnikova, Nataliia; Reshetniak, Natalia; Mashchenko, Maryna; Baranova, ValeriaThe concept of financial flows management of enterprise corporate security system is developed and justified in the article. The approaches to the assessment and analysis of the financial flow are analyzed. It is determined that the financial flow of enterprises' corporate security system should be understood as financial resources purposeful movement, which is a dynamic set in time and space within the logistics of processes at enterprises. The paper proves that the time factor is an important criterion for the industrial enterprise resource security management effectiveness because the duration of the time of any task depends on many interdependent cycles and parameters. It is emphasized that the vector of strategic goals in the multi-purpose model of integrated logistics processes at enterprises in a particular time period is complexly determined on the basis of various coefficients which are formed by the internal and external institutional environment analysis. It is confirmed that modeling of financial resources of integrated logistics processes makes it possible not only to form the optimal vector of strategic goals of the multipurpose model of integrated logistics processes but also to identify the interconnection between the composition and volume of incoming and outgoing financial flows of all enterprise integrated processes. Material flow management optimization as a key aspect of logistics activities is considered, which is achieved by attracting and allocating financial resources and realized in the financial flows of integrated logistics processes at enterprises. The urgency of the requirements of coherence of material, financial, informational, and other types of resource flows of integrated logistics processes at enterprises is determined. It is proved the topicality and relevance of algorithms implementation for finding and analyzing performance indicators and decision-making criteria, which form the basis of the decision-making system for effective management of industrial enterprises’ resource potential, including financial, in conditions of factors instability and significant changes in the micro and macroeconomic environment.Документ Cost-Effective Software and Hardware Complex to Ensure Security Against Unauthorized Use of Enemy Commercial Uavs on the Combat Territory(Institute of Electrical and Electronics Engineers, 2023) Pohasii, Serhii; Milevskyi, Stanislav; Bilotserkivskyi, Oleksandr; Baranova, Valeria; Ippolitova, Inna; Pyvavar, IrynaThe rapid development in unmanned aerial systems (UAS) has raised concerns about security in both civilian and military domains. Remote identification of UAS, crucial for ensuring legality and ownership verification in real-time, poses challenges. This article explores the improvement of software and hardware complexes to counter the unauthorized use of enemy commercial UAVs on combat territories. Different data transfer protocols used by UAS, such as MAVLink, DJI OcuSync, Lightbridge, Datalink, and LTE/4G/5G, are compared based on their technical characteristics. The article highlights the vulnerabilities in identity forgery that can compromise privacy and operational security, emphasizing the need for robust remote identification systems. It discusses controversies surrounding DJI's DroneID protocol and the utilization of the DJI AeroScope Monitoring System. The limitations and problems associated with existing hardware solutions are addressed, and the benefits of using budget-friendly equipment for combatting dual-purpose commercial UAS are highlighted. The proposed detection system offers cost-effectiveness, scalability, mobility, and adaptability to counter evolving enemy UAS control methods, ensuring improved security on the front lines.Документ The phenomenon of innovative development and modernization processes of Singapore(Wydawnictwo Wyższej Szkoły Technicznej w Katowicach, Poland, 2023) Baranova, Valeria; Shapran, Evgeniy; Smorodin, AndriyДокумент Price Environment for Gold and Silver in the Context of the Development of COVID-19(2020) Baranova, Valeria; Sergienko, Olena; Stepurina, Svitlana; Lyashenko, VyacheslavThe precious metals market is an integral part of the overall financial market.
