V.; Dunay, Anna; Калініченко, Антоніна ВолодимирівнаДокумент Application of Modern Enterprise Resource Planning Systems for Agri-Food Supply Chains as a Strategy for Reaching the Level of Industry 4.0 for Non-Manufacturing Organizations.(MDPI: Engineering Proceedings, 2023-07-18) Kopishynska, O. P.; Utkin, Y. V.; Sliusar, I. I.; Muravlov, V. V.; Makhmudov, H. Z.; Chip, L. O.; Копішинська, Олена Петрівна; Уткін, Юрій Вікторович; Слюсарь, Ігор Іванович; Муравльов, Володимир Вячеславович; Махмудов, Ханлар Зейналович; Чіп, Людмила ОлександрівнаThe Ukrainian Industry 4.0 strategy envisages the positioning of Ukraine as a high-tech, post-industrial country, integrated into global technological chains of value creation and producing unique engineering services and high-quality products. In particular, for the needs of the territorial communities of Ukraine in the conditions of war, the uninterrupted operation of agro-food supply chains and ensuring the ecological safety of these territories has become especially important. This paper explores the possibilities of creating a unified digital information space in a modern cloudbased enterprise resource planning (ERP) system to improve the management of all subjects in the territorial community and facilitate the transition to the Industry 4.0 technology landscape.Документ Augmented reality in the interests of ESMRM and munitions safety.(2019-10-08) Slyusar, V.

L.; Degtyareva, L. M.; Поночовний, Юрій Леонідович; Дегтярьова, Лариса МиколаївнаNowadays Markov Modelling Processes (MMP) found widely use into realm pertaining to availability assessments of diverse complex. technical systems and devices. In this regard, Cloud Server Systems (CSSs) are no exception. However, in order to leverage MMPs for the availability evaluation of CSSs the researchers should take into account that this assessmet procedure based on the utilization of just one distributio that is exponential distribution of times to failure, times 10 repair et prelit events and impacts. In that regard, that some groups of researchers into realm pertaining to CSSs availability are increasingly trying to leverage approaches based on Sem Markov Modelling Processes (SMMPs). Using SMMPs the researchers can consider more number of parametric characteristics and have a realistic picture as regards of availability level for the server system addition, seeking to improve overall availability of CSSs, the results for SMMPs in the so-called borders’ states, when Non-Markovian Process transforms at Markovian Process.Документ AvTA Based Assessment of Dependability Considering Recovery After Failures and Attacks on Vulnerabilities(2019) Ponochovnyi, Y.

L.; Illiashenko, O.; Поночовний, Юрій ЛеонідовичThe paper contains the results of the development and implementation of a cybernetic approach to the creation of resilient systems. The architecture of a resilient system contains redundant components compared to a traditional feedback control system. This is primarily due to the need to implement additional channels in the control system to respond to changes in requirements, environment, or unspecified faults and failures. The general structure of a resilient system is based on the principle of dividing control channels for functional and non-functional characteristics. This allows to react to changes in the information component of the environment during attacks on the system to ensure its cybersecurity. The case for a space resiient system with online verification is described. Three scenarios of the system behaviour to assure resilience are suggested and the first scenario is explored by the use of Markov model. That allows offering options for improving availability function and other indicators of resilient systems.Документ Cпроможності тропосферних станцій зв’язку на основі технології цифрових антенних решіток(2021-04-15) Слюсар, Вадим ІвановичДокумент Data Farming на основе пандемической статистики(2021-09-09) Слюсар, Вадим ІвановичДокумент Dependability Assessment for SCADA System Considering Usage of Cloud Resources(2020-05) Ivanchenko, O.; Kharchenko, V.; Brezhnev, E.; Ponochovnyi, Y. L.; Moroz, B.; Kabak, L.; Поночовний, Юрій ЛеонідовичControl (SCADA) system is one the most significant cyber-oriented components of management circuit for any complex hierarchical infrastructure. The effectiveness and performance of the SCADA system depends on a number of relevant factors including a possibility to utilize additional cloud resources. Of particular note, the cloud services ean apply in order to create concurrent redundant system for implementation of disaster recovery feature of SCADA information resources during different deliberate malicious impacts and intrusions. However, in spite of the fact that usage of the cloud services allow to enhance functionality of SCADA system, there are dependability and cybersecurity’ aspects for their joint utilization hat keep to remain a serious challenge for service personnel and users. In this paper, authors propose to employ analytical and stochastic modelling in order to get a numerical dependability assessment for SCADA system with realization of the cloud resourcing support considering influence of diverse negative factors, Furthermore, developers can utilize these modelling results in order to perform justification of overall functional requirements of the SCADA system.Документ Determining the Project Model for Implementation ERP Class Information System for the Resurses and Activities Management in Territorial Communities(ЛНУП, м.

V.; Protas, N. M.; Ключак, О.; Ластівка, О.; Семенюк, А.; Ківшар, О.In this study, the object of research is organizational and technical systems. The primary issue addressed is the enhancement of operational efficiency in assessing the state of such systems under constraints related to data reliability, regardless of the volume of incoming data acquired from information sources. The subject of the research is the process of evaluating the condition of organizational and technical systems. The study presents the development of a methodological approach for assessing the condition of complex organizational and technical systems. The originality of the proposed approach lies in the implementation of advanced auxiliary procedures that enable the following: – deployment of a search population of hippopotamus agents across the search plane, accounting for uncertainty in the information acquired through technical means about the organizational and technical system, by employing appropriate corrective coefficients. This enables a reduction in the time required for initial configuration of the subsystem responsible for processing heterogeneous data from extraction sources; – additional consideration of the velocity of each agent within the hippopotamus swarm, allowing the prioritization of search tasks by each individual agent within the corresponding search space (across elements and components of the organizational and technical system); – verification of the algorithm’s convergence to local and global optima; – replacement of ineffective search agents by refreshing the population of hippopotamus agents; – implementation of deep learning mechanisms for the knowledge bases of the hippopotamus agent swarm; – estimation of the required computational resources in cases where the available computational capacity is insufficient for performing the necessary calculations. An illustrative example demonstrated a 13–16 % increase in decision-making efficiency due to the integration of additional procedures, while ensuring a decision reliability level of 0.9Документ Development of a methodological approach to the research of special purpose communication systems(2022) Semenenko, I.; Artabaiev, Y.; Degtyareva, L.
