Публікація Simulation and optimisation of business process management: case study of IT company(2024) Serhiienko, Olena; Mashchenko, Maryna; Samorodov, Borys; Babichev, Anatoliy; Klimenko, OlenaIn managing business processes of complex hierarchical systems, primary attention is given to analysing, accelerating, and optimising the basic processes typical for any company. Objectives: The goal of this work is to prove that while managing business processes, it is crucial to consider the peculiarities of the external and internal environment to determine the effects of individual triggers. Method: An example of business process analysis was provided regarding the peculiarities of managing IT service companies operating in a dynamic environment of rapid technological changes. The business processes analysis of IT service companies in Ukraine was conducted. Business process groups characterised by low use of labour and financial resources and excessive and high levels of risk management were determined. Results: An algorithm for optimising the IT company's business processes was developed. Simulation and optimisation models for managing IT company business processes were developed using scenario modelling and simulation techniques. Conclusion: Based on these models, a predictive evaluation of management impacts on business processes was conducted, representing individual clusters according to defined management strategies.Публікація 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.Публікація 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.Публікація Cognitive technologies for modeling migration processes in education(Kaunas University of Technology, Lithuania, 2022) Sergienko, Olena; Mashchenko, Maryna; Gavkalova, N.; Chernova, L. S.; Lola, Yu.The cognitive model of regulating educational migration is constructed on the basis of an oriented graph-structured scheme of causal relations between system elements. This model, in contrast to others, combines factors, taking into account their interaction, leaving, and the educational conditions of foreigners, which in balance lead to educational migration. This model also determines the effects for the country, region, university, and individual migrants. The cognitive model is the basis for developing a set of scenarios. Scenario modeling allows for the identification of possible variants for the development of a situation, ways and mechanisms of influencing the situation in order to achieve the desired results and avoid undesirable consequences, and the development of a set of measures to influence the situation. Each scenario is characterized by the initial data, the influence of management, and the obtained result. Thus, all possible variants of system development are considered and the optimal management strategy is chosen to achieve the desired goals. Three core scenarios of development (optimistic, realistic, and pessimistic) were obtained on the basis of the cognitive model of educational migration regulation. Given these scenarios, methodological recommendations can be formulated on the regulation of educational migration in order to attract educational migrants to Ukraine from foreign countries. This will promote the interests of the social, economic, political, and demographic development of the country. The implementation of the proposed measures to regulate educational migration will facilitate the integration of domestic education and science into the global system, improve the quality of education and its competitiveness in international markets for educational services, increase income, and offset the negative effects of Ukraine’s demographic decline.Публікація Evaluation of the effectiveness of crediting management system of agrarian enterprises(Global Scientific Trend, 2021) Mashchenko, Maryna; Sergienko, Olena; Dykan, V.; Dykan, O.The state of governmental support for crediting of agricultural enterprises is analyzed. A comprehensive analysis of the state of agricultural enterprises crediting is carried out in all possible areas that allows to solve the main problems of agricultural enterprises crediting in Ukraine and shortcomings in the management of financial and credit relations at different levels and to identify the main factors of influencing the development and priority directions of crediting development. The complex of tasks for assessing the effectiveness of crediting management system of agrarian enterprises is determined. The three-level management system for the agroindustrial complex is proposed: agrarian enterprises - the object of management, regional bodies - the subject of the first level management, the state - a higher level management subject.
