Назва: Robust decentralization of information management systems Автори: Udovenko S. G.; Zatkhey V. A.; Teslenko O. V. Короткий огляд (реферат): An approach to determining control influences for a decentralized information management system that ensure its robustness to structural disturbances is considered. An algorithm for selecting a suboptimal strategy for forming controls over system objects is proposed.

Назва: Neural network technology for detecting errors in text documents Автори: Udovenko S. G.; Zatkhey V. A.; Teslenko O. V. Короткий огляд (реферат): The goal of this work is to develop a modified technology for error detection in text documents using a multilayer perceptron neural network. The proposed technology is implemented using an autoassociative neural network trained on a corpus of parallel texts containing distorted and corrected sentences. The feasibility of using the principal component method for preprocessing input text data is investigated. The test results confirm the effectiveness of the application of the studied technology for detecting errors in polythematic text documents.

Назва: Analysis of the effectiveness of software testing technologies for information systems Автори: Brynza N.; Lobanov K. Короткий огляд (реферат): The purpose of this work is to analyze the effectiveness of software testing. Modern approaches to software testing are analyzed, and their advantages, limitations, and areas of practical application are identified. To conduct a computational experiment, an experimental dataset in CSV format was created, containing approximately 15,000 records that characterize the testing parameters, specifically costs, execution time, and the number of defects found. Models were constructed to evaluate the economic efficiency of various testing types, enabling the determination of time limits for return on investment. Based on the results of the experiment, practical recommendations were formulated for choosing the optimal type of testing: manual testing is appropriate for small projects due to low costs, automated testing is appropriate for medium-sized projects with repetitive scenarios, and intelligent testing is suitable for large and dynamic systems where adaptability and high accuracy in detecting defects are critical.
