Документ Intelligent management of an innovative oil and gas producing company under conditions of the modern system crisis(2023) Krasnyuk, Maxim; Hrashchenko, Iryna; Goncharenko, Svitlana; Krasniuk, Svitlana; Kulynych, YuriiThis publication presents the part of the research results and practical results obtained by the authors regarding the hybrid use of economic-mathematical modelling, knowledge-oriented decision support technology of an oil and gas production company using fuzzy logical inference. The purpose of this research is the development of theoretical provisions of modelling and knowledge-oriented decision support means at the macro level of oil and gas production companies. The purpose of the work determined the solution of the following tasks: - development of science-based recommendations regarding the architecture of a knowledge-oriented DSS of an oil and gas company, the basic model of knowledge presentation, features of the logical conclusion mechanism, etc.; - development of a complex system of economic and mathematical support for decision-making at the macro level of an oil and gas production company in modern economic conditions. The object of the study is the oil and gas production industry. The subject of the research is information processes, economic-mathematical models and knowledge-oriented methods and means of supporting the adoption of management decisions at the strategic level on economic and production issues of the domestic oil and gas production project. Methods/Approach: Economic and mathematical methods, methods of artificial intelligence, methods of logical generalization, expert evaluations and situational approach are used to solve the tasks set in the work. Results: The main scientific result of the work consists in the creation of the concept that allows creating a hybrid DSS of an oil and gas company on the basis of the developed systems of economic and mathematical decision-making support at the macro level of an oil and gas production company, focused on knowledge of technology and intelligent technologies. Conclusions: The scientific, theoretical and applied practical solutions proposed in this publication are universal for implementation by both state and private oil and gas resident and non-resident companies for emerging markets, however, in order for a specific oil and gas company to obtain special additional competitive advantages over others, additional industry-specific Big Data Analysis of collected and stored heuristics, expertise and project development are requiredДокумент Strengthening green taxation within the framework of fulfilling the green deal conditions in the context of formation of the environmental security system of EU countries(2024) Nikiforov, Petro; Abramova, Alla; Zhavoronok, Artur; Bak, Nataliia; Yaremchuk, Vitalii; Kulynych, YuriiThe study is dedicated to the scientific justification of the need to strengthen green taxation in the context of the Green Deal implementation and the greening of EU countries based on a comprehensive analysis of the effective functioning of the green taxation system, and presents the following vectors of its improvement. Scientific approaches to the interpretation of the essence of the economic value of green taxation, taking into account the systematicity of the economic, socio-political, innovative and infrastructural goals in the conditions of modern challenges, have been studied. Based on the international system of economic indicators, in particular the Environmental Policy Stringency Index, the actual state of green taxation in EU countries was assessed. By applying a methodological approach based on comparing the cost characteristics of regulation and stimulation of the ecologically oriented business activity of business entities with the cost characteristics of the tax burden and the regulatory nature of the impact due to the use of environmental taxation objects and damage to the environment, an assessment of the effectiveness of green taxation was carried out in 12 EU countries. The architecture of the environmental taxation environment of EU countries is presented, the interrelated elements of which are defined as the legal framework of green taxation, the toolkit for the Green Deal implementation with an emphasis on green taxation, as well as systemically important market transformations capable of influencing the economic and environmental behavior of business entities by using natural resources and pollution of the natural environment under the influence of time factors, globalization changes and subsequent future uncertainties. The author's approach to increasing the efficiency and improvement of green taxation, which is expedient to implement to achieve the Green Deal goals and the formation of the environmental security system of the European region, is substantiated.
