The peculiarity is that <strong>each problem is considered from two sides - the economist’s and the engineer’s</strong>, for example, in the context of forming the «price – quality» criterion, in which the first component concerns research in the field of business economics, and the second - engineering. The research result at the intersection of these disciplines can be used in the actual production to identify reserves, providing the opportunity to reduce costs and improve product competitiveness.</p> https://journals.uran.ua/tarp/article/view/322457 Optimization of pump jack electric drive operation taking into account reservoir flow rate 2025-02-07T16:54:21+02:00 Andriy Malyar andrii.v.maliar@lpnu.ua Mykola Malyar andrii.v.maliar@lpnu.ua <p><em>The object of the study are the processes occurring in electric drives of sucker rod pumping units, which are used for mechanical oil production.</em></p> <p><em>When designing oil pumping units, one of the issues is the synthesis of control systems for the electric drives of pump jacks. In the synthesis of the control system, it is important to take into account as many factors as possible that influence the performance of the well and its equipment. When synthesizing the criterion for optimal operation of the system, it is necessary to take into account changes in the technical condition of the oil production facility and the conditions of the reservoir operation. This is implemented using a control system that adjusts the electric drive speed according to the real operating conditions of the well. This approach allows improving the productivity of the oil pumping unit and increasing its economic efficiency.</em></p> <p><em>The main focus is on the synthesis of a control system for the electric drive of a pump jack, which makes it possible to balance the intensity of fluid inflow into the well and its withdrawal. An optimization criterion is proposed, which takes into account different fluid inflow rates, thus adapting the electric drive operation to the specific conditions of each well.</em></p> <p><em>The study used the theory of classical variational calculus. To find the minimum of the functional, and therefore the optimal parameters of the control system, a quadratic form, which is a Lyapunov function, was used.</em></p> <p><em>The study resulted in the formulae for calculating the key operational parameters of the pump jack electric drive. The synthesized optimization criterion links the unit's productivity to parameters such as the number of crankshaft rotations, the rod pump delivery coefficient, and the load torque of the drive motor.</em></p> <p><em>In practice, the proposed optimization criterion for the electric drive operation will enable improving the efficiency of the oil pumping unit through the rational selection of the drive motor's speed and torque. This, in turn, will enhance the well's operating conditions and extend its operational life.</em></p> 2025-02-10T00:00:00+02:00 Copyright (c) 2025 Andriy Malyar, Mykola Malyar https://journals.uran.ua/tarp/article/view/322308 Development of ways to improve strategic financial planning in an enterprise 2025-02-04T16:55:58+02:00 Maria Iorgachova manadger413@i.ua Olena Kovalova o.m.kovalova@op.edu.ua Viktoriia Kirsanova v.v.kirsanova@op.edu.ua <p><em>The research object is the issue of strategic financial planning at enterprises under conditions of high uncertainty in the external economic environment.</em></p> <p><em>One of the most problematic aspects is the need to improve strategic financial planning in conditions of economic turbulence, as its successful implementation is a prerequisite for financial stability and effective operations.</em></p> <p><em>The research utilized methods of analysis and synthesis, critical analysis and generalization methods, graphical methods, an algorithmic approach, and an expert method.</em></p> <p><em>A set of universal practical recommendations has been developed to improve the process of strategic financial planning at enterprises by generalizing conceptual theoretical and methodological foundations.

They also account for the peculiarities of different development stages, enterprise-specific activities, as well as various tools and approaches to achieve the primary goal. The study identifies barriers complicating the implementation of strategic financial planning at Ukrainian enterprises, including a lack of financial resources, the complexity of planning methodologies, and the high uncertainty of the external environment.</em></p> <p><em>The developed pool of recommendations enables improvements in a set of key performance indicators for the functioning of business entities by integrating these recommendations into the process of strategic financial planning. Achieving a qualifying effect becomes possible through the simultaneous use of ratio analysis combined with a balanced scorecard system, forecasting, and a scenario-based approach. The proposed authorial approach represents the most suitable option for implementing strategic financial planning under modern conditions. Compared to similar known approaches, it offers advantages such as cost optimization, clarification of the qualifying impact of factors on resulting indicators, and integration of advanced methodologies.

The study's object is to model military game scenarios, in particular, the role of artillery forces in countering an amphibious operation of one or two divisions. One of the most problematic areas is combining continuous fire support and maneuvering to maintain artillery survivability and save ammunition with limited resources.</em></p> <p><em>The study used mathematical models of combat resource utilization based on Markov chains, taking into account the probabilistic aspects of target destruction. Simulation models were also developed for various scenarios of countering amphibious assault ships, which allows for optimizing the number of shells and determining the most effective moments for opening fire.</em></p> <p><em>Several approaches to firing have been developed and analyzed: methods of minimizing the number of shells, rapid neutralization of enemy targets, and mixed methods that allow finding a balance between minimizing resources and speed of response. Each method has its advantages depending on the combat situation: cost minimization methods are suitable for controlled scenarios. Instead, methods of rapid destruction are effective in high-risk situations but require more resources. A new mixed tactical method has been developed. This is because the proposed methods have several features, in particular, a large discrepancy in the predicted minefield, which also made it possible to assess the ability to hold the minefield of the fairway, which is important for protection against further attacks. This ensures the possibility of obtaining a high level of minefields on the fairway (up to 67.77 %). Compared to similar indicators, which ranged from 46.42 % to 67.77 %, but without specifying the method, this provided advantages in the form of the possibility of tactical maneuvering between the proposed methods, depending on the current state of resources and the proximity of enemy targets.</em></p> 2025-01-29T00:00:00+02:00 Copyright (c) 2025 Maksym Grishyn, Oksana Maksymova, Kateryna Kirkopulo, Oleksandr Klymchuk https://journals.uran.ua/tarp/article/view/322052 Development of innovation projects based on the synergy TRIZ principle and AI technology 2025-01-30T19:27:27+02:00 Sergey Bushuyev SBushuyev@ukr.net Natalia Bushuyeva Natbush@ukr.net Andrii Puziichuk a.puziichuk2018@meta.ua Denis Bushuiev bushuyevd@gmail.com <p><em>The object of the research is a novel development methodology for innovation projects that leverages the power of the synergy principle of the Theory of Inventive Problem Solving (TRIZ).

By integrating the structured problem-solving framework of TRIZ with the analytical power of AI, a novel approach is proposed to enhance the evaluation and optimization of innovation initiatives.

The empirical estimates obtained for individual countries show significant differences in the impact of fiscal freedom and the rule of law on income. This allows to better understand the specifics of fiscal policy and institutional transformation in the selected countries. There are several main results. First, improving the financial situation is favorable for economic growth in Poland, Romania, and Ukraine, but unfavorable in the Czech Republic (there is no effect in Hungary). Second, it was found that lower government spending is beneficial for economic growth only in Romania and Hungary (to a lesser extent). At the same time, for the Czech Republic and Ukraine, an increase in government spending is preferable. Third, the protection of property rights encourages economic growth only in Ukraine. The inverse relationship for Central and Eastern European countries may mean that administrative guarantees in the area of property rights are much stricter than the achieved income level would suggest. Fourth, the efficiency of the judicial system is found to encourage economic growth in 4 out of 5 countries except the Czech Republic.</em></p> <p><em>The paper confirms the findings of other studies for Central and Eastern European countries and Ukraine that currency devaluation in nominal and real terms hinders economic growth. Money emission and interest rate increases in the US are favorable for economic growth in all countries. The consequences for economic growth of the increase in global crude oil prices, the COVID-19 pandemic and the period of extremely low interest rates (ZLB) in 2010–2020 differ across countries.</em></p> 2025-02-14T00:00:00+02:00 Copyright (c) 2025 Mariia Blikhar, Solomiya Sokurenko, Andrii Hodiak, Yuliia Ilkiv, Mariana Kashchuk, Anatolii Kucher https://journals.uran.ua/tarp/article/view/322370 Development of a semantic structure for the composition of cognitive web services 2025-02-06T16:10:27+02:00 Ihor Kasianchuk kasyk3@gmail.com Anatoliy Petrenko tolja.petrenko@gmail.com <p><em>The object of the research is the semantic structure for the composition of cognitive web services. The framework is designed to model, search, and orchestrate cognitive web services, including functionalities such as text recognition, language translation, and sentiment analysis, within dynamic environments. The problem addressed is the lack of efficient and scalable mechanisms for the automated discovery and composition of cognitive web services that can adapt to changing requirements and meet Quality of Service (QoS) constraints. Existing approaches often rely on static rules or keyword-based searches, which fail to provide adequate precision, adaptability, or scalability for complex service ecosystems.</em></p> <p><em>The key result of the study is the development of a semantic framework that integrates ontology-based service modeling with logical inference using SWRL (Semantic Web Rule Language) rules. The framework supports dynamic service composition by leveraging semantic relationships between services, input/output data, and constraints such as execution time and accuracy. The results demonstrate higher semantic precision, better adaptability to changes, and improved QoS compliance compared to existing approaches. This is achieved through the use of a formalized ontology for precise service representation, SWRL rules for automated inference, and dynamic service composition based on semantic relationships, which improves query matching and reduces execution time.</em></p> <p><em>The proposed framework can be practically applied in environments requiring adaptive service orchestration and composition, such as intelligent automation systems, cloud-based service ecosystems, and IoT (Internet of Things) applications. Its effectiveness is especially evident in scenarios involving complex multiservice workflows where traditional approaches are inefficient. The framework's extensibility ensures its applicability across various domains, with minimal customization required to incorporate new services or workflows.</em></p> 2025-02-07T00:00:00+02:00 Copyright (c) 2025 Ihor Kasianchuk, Anatoliy Petrenko
