Документ Assessing the Economic and Technical Effectiveness of Intercepting UAVs Using Alternative Methods(2023) Pohasii, Serhii; Mashchenko, Maryna; Serhiienko, Olena; Klimenko, Olena; Andriushchenko, Tetiana; Milevska, TetianaThe study explores the various methods and technologies employed in intercepting unmanned aerial vehicles (UAVs). It highlights the use of UAV interceptors, specifically those utilizing the kamikaze scenario, which have demonstrated effectiveness in conflicts such as the war in Ukraine. The research investigates the technical and economic aspects of combating UAVs, particularly reconnaissance and kamikaze UAVs equipped with various types of ammunition. Cost analysis and technical characteristics of commonly used kamikaze UAVs are examined. This study provides valuable insights into the challenges and potential solutions in countering UAV threats.Документ Assessment of volatility and the level of hedging effectiveness on oil markets(Wydawnictwo Wyższej Szkoły Technicznej w Katowicach, Poland, 2023) Haponenko, Olha; Mashchenko, Maryna; Serhiienko, OlenaДокумент 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 Modeling Internationally Diversified Investment Portfolio(Institute of Electrical and Electronics Engineers, Inc., USA, 2020) Chernova, Natalia; Mashchenko, Maryna; Sergienko, Olena; Bilotserkivskyi, Oleksandr; Shapran, OlenaA diversified portfolio can deliver improved performance and lessened risk relative to not diversified one. The diversification may be achieved in different ways: an investor may allocate money in different asset classes; or in stocks of different industries; or in bonds with different maturities; or in stocks with large, middle and small market capitalization; or in different commodities and so on. Another way is international (global) diversification. The paper aim is to form an optimal investment portfolio containing assets of different countries. To achieve this the following tasks should be solved: carry out a preliminary financial analysis of assets (stock indices) of different countries and determine the set of assets that are eligible for investment; form an optimal portfolio of selected stock indices; carry out a comparative analysis of the efficiency of the obtained portfolio and the benchmark portfolio, which is domestically oriented. The proposed algorithm for modeling internationally diversified optimal portfolio includes the following core steps: forming the information base of the research; classification of assets into homogeneous groups and detecting the group that is suitable for the investment; modeling diversified portfolio and a benchmark portfolio; comparison of obtained portfolios performance.Документ Project management of innovation and investment activities to ensure agricultural entities economic security in Ukraine(2021) Makovoz, Oksana; Mashchenko, Maryna; Lesnaya, Iryna; Ponomarenko, Oleksandr; Savytska, LarysaThe purpose of this article is to justify the project management of innovation and investment activities to ensure economic security of agribusiness entities based on increasing the efficiency of innovation and increasing competitiveness in the Ukrainian economy. It is proved that investment and innovation policy to ensure economic security involvesimplementing state investment priorities capital and growth of investments in rural development. Factors influencing the growth of equity of agro-industrial enterprises are identified with factor analysis. It allows increasing the socio-economic efficiency of agricultural production.
