Документ The method of constructing a development trajectory as the basis of an intelligent module for strategic planning of the EPM system(CEUR Workshop Proceedings, 2021) Moskalenko, V. V.; Fonta, N.; Москаленко, В. В.; Фонта, Н. Г.The application of computational intelligence methods for solving strategic problems based on the analysis of research in the field of strategic management and forecasting is considered. The description of the process of forming strategic goals for the company as procedure of the business process to form the company development program is presented. This business process is implemented as a separate module of the strategic planning subsystem of the Enterprise Performance Management system. A solving for theproblem of choosing strategies to achieve strategic goals is proposed. The choice of strategies is based on the analysis of development trajectories. A method for constructing a development trajectory is proposed.The method uses the idea of a sequential analysis of options. Each point of development trajectory will correspond to market positions that the company must have at strategic intervals in order to achieve the strategic goal. Possible market conditions (company positions) at intervals of the planning period are determined based onpredicted values of market parameters and solving the segmentation problem. The segmentation problem is formulated as a classification problem and is implemented by one of the Machine learning methods. Forecasting is based on neural networks. It is proposed to use a neural network with the Temporal Fusion Transformer architecture.Документ Дослідження нейронних мереж для прогнозування вартості акцій компаній у нестабільній економіці(Національний технічний університет "Харківський політехнічний інститут", 2022) Москаленко, В. В. ; Санталова, А. Р.; Фонта, Н. Г.; Moskalenko, V. V. ; Santalova, A. R.; Fonta, N.Дані дослідження присвячені аналізу і вибору нейронних мереж різної архітектури та гібридних моделей, до яких включені нейронні мережі, для прогнозування ринкової вартості акцій на фондовому ринку країни, яка перебуває у процесі нестабільного розвитку. Аналіз та прогнозування таких фондових ринків не може бути проведено з використанням класичних методів. Актуальність теми дослідження зумовлена необхідністю розробки програмних систем, які реалізують алгоритмічне забезпечення прогнозування ринкової вартості акцій в Україні. Впровадження таких програмних систем до контуру прийняття інвестиційних рішень у компаніях, які зацікавлені у підвищенні інформаційної прозорості фондового ринку України, дасть можливість покращити прогнози щодо ринкової вартості акцій. Це у свою чергу сприятиме покращенню інвестиційного клімату та забезпечить зростання інвестування в українську економіку. Проведено аналіз результатів існуючих досліджень щодо використання нейронних мереж та інших методів обчислювального інтелекту для моделювання поведінки учасників фондового ринку та прогнозування ринку. У статті надано результати дослідження щодо використання нейронних мереж різної архітектури для прогнозування ринкової вартості акцій на фондових ринках України. Для прогнозування було обрано чотири акції Української фондової біржі: Центренерго (CEEN); Укртелеком (UTLM); Крюківський Вагонобудівний Завод ПАТ (KVBZ); Райффайзен Банк Аваль (BAVL). Для експериментального дослідження були обрані такі моделі: довга короткострокова пам’ять LSTM; згорткова нейронна мережа CNN; гібридна модель, яка поєднує дві нейронної мережі CNN і LSTM; гібридна модель, що складається з алгоритму декомпозиції варіаційного режиму та нейронної мережі довгострокової пам’яті (VMD-LSTM); гібридна модель VMD-CNN-LSTM глибокого навчання на основі варіаційного режиму (VMD) та двох нейронних мереж. Розраховано оцінки якості прогнозу за різними метриками. Зроблено висновок, що використання гібридної моделі VMD-CNN-LSTM дає мінімальну помилку прогнозування ринкової вартості акцій українських підприємств. Також доцільно використовувати модель VMD-LSTM для прогнозування на біржах країн з нестабільною економікою.Документ Information technology of determination the company's financial condition for the financial planning subsystem of the EPM system(Національний аерокосмічний університет ім.

V.; Santalova, A. R. ; Fonta, N.; Nikulina, O. M.; Москаленко, В. В.; Нікуліна, О. М.The relevance of this research topic is due to the need to develop algorithmic provision of the market value forecasting for shares in Ukraine and the introduction of the concept for increasing information transparency of the domestic stock market. All this will help improve the investment market, provide investment and development of Ukrainian companies and the economy as a whole. An analysis of researchon the use of methods for computational intelligence, including neural networks to model the behavior of stock market participants and solve the problem of forecasting. A study was conducted based on using neural networks of different architecture to predict the market value of shares in the stock markets of Ukraine, which are in the process of formation and development. The following models of neural networks were chosen for experimental research: Long short-term memory; Convolutional neural network; a hybrid model that combines two neural network architectures CNN and LSTM; a hybrid model consisting of a variational mode decomposition algorithm and a long-term memory neural network (VMD-LSTM). Four shares of the Ukrainian Stock Exchange were selected forforecasting: Tsentrenergo (CEEN); Ukrtelecom (UTLM); Kriukivs’kyi Vahonobudivnyi Zavod PAT (KVBZ); Raiff Bank Aval (BAVL). Estimates of forecast quality are calculated. It was concluded that it is advisable to use the LSTM network to forecast stocks that are on the stock exchanges of countries with unstable economies.Документ Financial Sustainability Evaluation and Forecasting Using the Markov Chain: The Case of the Wine Business(MDPI, 2020) Rekova, N. Yu.; Telnova, H.; Kachur, O.; Golubkova, I.; Balezentis, T.; Streimikiene, D.; Рекова, Н. Ю.This paper proposes a framework for assessing the financial sustainability of a wineproducing company. The probabilistic approach is used to model the expected changes in the financialsituation of an enterprise based on the historical trends. The case of an enterprise in Ukraine isconsidered as an illustration. The Markov chain is adopted for the forecasting exercise. Using theMarkov chain framework allows one to predict the probability of financial security change forseveral periods ahead. The forecast relies on the transition probabilities obtained by exploiting thehistorical data. The proposed framework is implemented by construction of the financial securitylevel transition matrices for three scenarios (optimistic, baseline and pessimistic). The case studyof a Ukrainian wine producing company is considered. The possibilities for applying the proposedmethod in establishing anti-crisis financial strategy are discussed. The research shows how forecastingthe financial security level of a company can serve in anti-crisis financial potential buildup.Документ Analysis of the stability factors of Ukrainian banks during the 2014–2017 systemic crisis using the Kohonen self-organizing neural networks(LLC “Consulting Publishing Company “Business Perspectives”, 2019) Mints, A. Yu.; Marhasova, V.; Hlukha, H.; Kurok, R.; Kolodizieva, T.; Мінц, О. Ю.The article proposes an approach to analyzing reliability factors of commercial banks during the 2014–2017 systemic crisis in the Ukrainian banking system, using the Kohonen self-organizing neural networks and maps. As a result of an experimental study, data were obtained on financial factors affecting the stability of a commercial bank in a crisis period.It has been concluded that during the banking crisis in Ukraine in 2014–2017, the resource base of a bank was the main factor of this bank stability. The most preferred sources of resources were funds from other banks (bankruptcy rate of 5.7%) and le-gal entities (bankruptcy rate of 8%), and the least stable were funds from individuals (bankruptcy rate of 28.5%).The relationship between financial stability and the amount of capital and the structure of bank loans is less pronounced. However, one can say that banks that focused on lending to individuals experienced a worse crisis than banks whose main borrowers were legal entities.The tools considered in the article (the Kohonen self-organizing neural networks and maps) allow for efficiently segmenting data samples according to various criteria, including bank solvency. The “hazardous” zones with a high bankruptcy rate (up to 49.2%) and the “safe” zone with a low rate of bankruptcy (6.3%) were highlighted on the map constructed. These results are of practical value and can be used in analyzing and selecting counterparties in the banking system during a downturn.
