Документ Information systems and technologists and economists(Національний технічний університет "Харківський політехнічний інститут", 2024) Zhu, Xiaoyi; Kramskoi , D. Ju.Information systems and technologies in the economy play an important role in ensuring the efficiency, competitiveness and innovation of business. They allow you to collect, process, analyze and use data for making management decisions, planning resources and automating many business processes.Документ Aspects of the development of the comprehensive information security system in the information systems(Харківський національний університет радіоелектроніки, 2020) Nosyk, Andrii Mihajlovych; Kucherenko, Yurii; Nosyk, Kateryna AndriivnaHere are considered some aspects on the comprehensive information security system development of any information system of civil purposes, which manages the critical infrastructure or process in a relevant field, or control systems for special purposes. The basis for the functioning of these systems is information, and because of it the issue of protection is paramount in their functioning. The questions on the choice of general security policy in them, the choice of methods for identification and authentication, authentication of documents, circulating them. This will conceptually define the future of information security records they elaborate.Документ Features of information systems audit in the digital economy(Національний технічний університет "Харківський політехнічний інститут", 2024) Wang, Wei; Havrys, Olha O.In the context of the digital economy, information systems audit professionals must not only master basic theoretical knowledge of auditing, but also acquire professional knowledge of information technology, become interdisciplinary professionals who can skillfully use information technology to collect and analyze data, and have the ability and experience to evaluate data for information system management.Документ Problems of assessing the economic efficiency of information systems for retail enterprises(Одеська національна академія харчових технологій, 2021) Liutenko, Iryna Victorivna; Bieliaiev, Oleksandr IhorovychThe problems of assessing the economic efficiency of information systems were considered on the example of the retail business. The features of the business model of enterprises that significantly affect functional requirements for information systems and priorities were considered. Multicriterial evaluation problems were considered. Development of the software that will perform multicriterial assessment of information systems for retail trade based on user-entered data were proposed. The software users were divided into categories depending on their theoretical knowledge in the field of marketing and trade and experience with information systems.Документ Punctured NCC codes for information protection in information and measurement systems(Національний технічний університет "Харківський політехнічний інститут", 2022) Krylova, Victoria; Tverytnykova, Elena; Vasylchenkov, Oleg; Kolisnyk, TatyanaDuring development and design of information-measuring systems, enabling to carry out collection, processing and transmission of information, one of the main problems is the choice of effective methods of information protection against defects in noisy communication channels. Effective use of frequency-time resources of information communication channels, as the most valuable part of the information transmission system, is the key to provide reliable delivery of transmitted messages. One of effective directions of reliability increase and information transfer reliability in information-measuring communication networks is implementation of methods and algorithms of noise-resistant coding, providing for detection and coping with errors, arising due to interferences in the communication channel. In this case, the choice in favor of one or another coding method depends on the information characteristics of the data channel. Parameters of the noise coder must be coordinated with the source of the message, the communication channel, as well as the requirements for the reliability of bringing information to the recipient. The problem of obtaining a wide range of codec parameters with simultaneous preservation of the unified macrostructure of the codec in communication systems causes the need for research on the development of adaptive algorithms for error information protection. In the article the research results of the characteristics of variable rate slot convolutional codes for adaptive coding/decoding in information-measuring systems of information transmission are proposed. Consequently, when creating communication networks, there is no need to use a large number of different codecs, even with completely different requirements to the code rate, channel rate and gain due to coding. In addition, there is a real opportunity to create terminal equipment, working on unified algorithms of protection against errors and access.Документ Синтез квазиоптимального обнаружителя трасс воздушных объектов запросными системами наблюдений единой информационной сети(Харківський університет Повітряних Сил ім. Івана Кожедуба, 2009) Обод, Иван Иванович; Заволодько, Анна ЭдвардовнаПриводится синтез квазиоптимального обнаружителя трасс воздушных объектов по данным запросных систем наблюдения единой информационной сети в последовательной постановке вопроса обнаружения в рассматриваемых информационных системах: обнаружитель ответных сигналов, обнаружитель воздушного объекта и собственно обнаружитель траекторий. В результате структура синтезированного квазиоптимального обнаружителя трасс воздушных объектов запросными системами наблюдения более унифицирована в схемотехническом построении.Документ Towards modeling of comprehensive assessment for licensing in higher education(Технологический Центр, 2013) Cherednichenko, Olga; Yanholenko, Olha; Liutenko, Iryna Victorivna ; Pylypenko, A.In the modern society information technologies, services, quality become the determinative factors of success of any business. The questions of quality management are especially relevant in social sphere, since organization oriented on quality of its processes provides the improvement of people living standards. Information computer technologies (ICT) are the powerful tool for increasing the performance of decision-making processes. Formalization of management problems and adequate mathematical models provide ICT with techniques and methods of solving the application problems in different domains and improving business performance. Higher education is a unique social and economic environment. The quality of its functioning influences many processes of successive development of society.Therefore elaboration of ICT in higher education domain remains the challenging problem for specialists in computer sciences.Документ Analysis of using information technologies іn systems with dual processes(Національний технічний університет "Харківський політехнічний інститут", 2019) Morozova, OlgaThe article deals with the analysis of using information technologies in systems with dual processes. It was shown how concepts information systems and technologies relate. The information system is the main medium for information technology. Information technology is a combination of techniques and processes, with clear rules and actions. Without knowledge of the oriented information technology, it is impossible to realize information system. The information system uses information technology to support decision making. At present, using of information technologies in the educational systems of 1-2 levels of accreditation is increasing. There are some opportunities for application of network technologies for the purpose of training, which allow the transfer of information of any kind and volume on-line to any distances, as well as interactivity and visibility of providing training materials. Among the information systems and technologies used in the higher education institutions, the most popular are web-technologies; intellectual computer programs, training; information technologies of decision making support and expert systems.Besides, creation of personal websites for teachers is particularly popular, thanks to these websites the teacher demonstrates hiseducational research activity, communicates with representatives of scientific schools and student communities, and thereby shares his experience and scientific achievements. After analysing the information systems and modelling tools in the production systems, it shows using some of the considered systems and tools in combination for divisions of the industrial enterprise. The structure of the industrial enterprise is divided into main blocks and each of them uses its ownsoftware product.
