Business performance assessment is one of the basic tasks of management. Business performance can be assessed using a number of methods. The basic ones include financial analysis, Balanced Scorecard or Economic Value Added (EVA). The paper is focused on SME business performance assessment based on Economic Value Added, calculated using the INFA build-up model. According to this method, companies were divided into four categories. The first category included companies with a positive EVA value. The second category included companies with negative EVA, but with the economic result above the risk-free rate. The third category included companies with a positive economic result above the risk-free rate. The fourth category included companies with a negative economic result. The model did not include companies with negative equity. The input represented 15 predictors based on their financial statements. The data were normalized and all extreme values, likely caused by a data rewriting error, were removed. Company performance is visualized by comparing Principal Component Analysis and Kohonen neural networks. Compared to similar research, the methods are compared using the data that analyzes the performance of companies. Both methods made it possible to visualize the given task. With regard to the purpose of facilitating the interpretation of the results, for the given case, the use of PC seems to be more appropriate.

Problems and Perspectives in Management Volume 18, 2020 Issue #3 pp. 81-92 Views: 894 Downloads: 219 TO CITE АНОТАЦІЯIt is necessary to choose proper methodology and indicators for assessing sustainable economic development as the information becomes a tool for decision-making support of sustainable development policies and implementation of programs. In Ukraine, evaluating the results of implementation of different programs for development is essential as an analytical basis for making a strategy for the next period and a prerequisite for further progress.
Certain shortcomings of linear models for evaluating the results appeared during the design and implementation of the strategy to manage sustainable economic development. The potential for establishing erroneous targets increases in the formation of strategic objectives for the next forecast period. There is a special need to choose adequate indicators to comprehensively approximate the factors of economic development and evaluation methods that allow more sensitively measuring the results of management decisions in the implementation of the strategy.
The article evaluates the results of the Sustainable Development Strategy “Ukraine – 2020”, employing the potential of the neural network method for a flexible combination of a large number of factors in constructing nonlinear models of impact on the resulting indicator. As a result of applying the neural network model with one hidden layer for evaluation, based on 16 indicators identifying economic, social, and institutional aspects of sustainable development of Ukraine, it was found that institutional transformations contribute most to achieving sustainable development. Reforms in terms of deregulation and support of entrepreneurship, property rights protection, and competitive environment have the most significant positive impact. On the other hand, low efficiency of capital market reforms, implementation of the energy efficiency program, and reform in the field of public procurement determine the need to revise the program of their fulfilment. -

Problems and Perspectives in Management Volume 22, 2024 Issue #2 pp. 1-16 Views: 394 Downloads: 96 TO CITE АНОТАЦІЯRussian aggression adversely affected the economy of Ukraine and emphasized the need to adapt the best practices of EU countries to determine steps to restore the country’s competitiveness. This study aims to determine the influence of the innovative development of countries on their competitiveness and identify prospects for Ukraine’s post-war economic recovery. The study constructed neural networks to assess the relationships between the factors of innovative development and the competitiveness of the EU countries and Ukraine. Six main factors of innovative development of countries are identified: “innovations in business (S1),” “intellectual property (S2)”, “innovations in industry (S3),” “eco-innovations (S4),” “innovation management (S5),” and “digital innovations (S5).” Groups of factors are determined by the strength of influence (strong, moderate, or weak). For Ukraine, S1 and S6 have a strong effect (33.3%), S5 shows moderate (16.7%), S2, S3, and S4 show weak effects (50%). For EU countries, S1 and S6 have a strong influence, S2 and S3 – moderate, S5 and S4 – weak. This comparative analysis concluded that EU countries consider intellectual property, green economy, and state innovation policy as key components of their competitiveness. The results discovered a weak relationship between intellectual property protection, innovation in industry, and competitiveness of Ukraine compared to EU countries. However, digital innovations significantly and positively affect Ukraine’s competitiveness.
