In present-day industrial control systems responsible for effective and safe operation of nuclear power plants (NPP), the databases of the upper level playa crucial role in process monitoring and control as they acquire, process, and present to the operator the data from all the lower-level systems. Moreover, the air-gapped separation of the upper level makes them extremely valuable for the entire manufacturing management. The specific feature that should be taken into account when dealing with databases of upper level control systems is that they are not perfectly stable and due to the modifications being introduced in lower-level systems subject to changes at all stages of the life cycle. The problem of making changes to the databases combining information of all lower-level devices and so being highly complicated happens to be particularly serious. The article considers the databases of NPP upper level control systems and delves into the problem of making changes to them. A brief overview of the upper level control system illustrating the importance of databases is presented. The description of working databases is provided, their characteristic features are highlighted and the basic principles of the methods for making changes to them are disclosed.

The paper proposes a method, an algorithm and scenarios of the use of a group of unmanned aerial vehicles (UAVs) as base stations to provide radio communication for a group of ground mobile agents (GMAs) as part of heterogeneous dynamic technical systems (HDTSs) operating in an intelligent environment. The work gives the mathematical description of the problem of choosing sub-optimal (rational) composition and spatial distribution of the UAV s, and calculating the coverage range (radius) for DAV-DAV and DAV - GMA links respectively. The proposed algorithm allows forming the composition of the DAV group (iteratively) to ensure that the coverage for the GMAs when moving in a given region. The algorithm checks the expediency of moving the D A V s (or their operation in current positions), moves additional DAVs from the base or returns unused DAVs to the base (changes their state to inactive), if necessary. The main tasks to be performed by the HDTS (composed of the groups of DAVs and GMAs) have been determined. The paper proposes several scenarios for the use of the UAVs to ensure radio communications for ground mobile agents. The work offers the requirements to the developed solution as part of the security monitor of a HDTS, including the functionality, a set of target parameters, and the main events/possible failures that can occur during the mission

The paper discusses key aspects of the digitalization of nuclear power in the context of the transition to Industry 5.0. The topic's relevance is due to the global transition of world industries to the concept of Industry 5.0, which is focused on integrating digital technologies, strengthening the human-centricity of management services, and increasing their adaptability to new challenges. Particular attention is paid to the use of digital twins and intelligent operator support systems (IOSS) at nuclear power facilities, which transforms their management, considering modern safety, reliability, and efficiency requirements. The paper describes the principles of creating digital twins of NPPs and considers the role of IOSS, the main tasks of which are to increase the level of awareness of NPP operators about the current state of the system, reduce the response time to emergency events, and automate decision-making. The authors propose an algorithm for interacting with a digital twin and IOSS, including collecting and processing data from real systems, modeling in a virtual environment, forecasting scenarios, and recommendations to the operator for optimal control. The algorithm ensures synchronization of the digital model with actual processes, optimization of operating parameters, and increased safety through early detection of deviations. The paper also focuses on the connection of the algorithm with the principles of Industry 5.0.

The article discusses an approach that combines expert systems and dynamic models in an intellectualized operator information support system (IOISS) for nuclear power plant units. The main goal of this approach is to provide operators with the most complete and accurate information for the efficient management of power units (PU). The main functions of the IOISS of NPP PUs are highlighted, and a path is proposed for their full-scale implementation based on the use of predictive dynamic modeling of PU parameters and expert systems (ES). The use of predictive dynamic modeling makes it possible to predict the behavior of a power unit based on available data and calculate optimal control parameters. ES, in turn, provides expert knowledge and specialist experience, allowing operators to make informed decisions and respond to possible emergencies. The structure of the ES, which is part of the IOISS and includes modules for data analysis, decision-making, and information visualization, is considered. All these components work together to ensure the efficient and reliable operation of NPPs. This approach to IOISS is the basis for developing upper-level systems for instrumentation and control systems of NPPs. It can significantly improve the safety and efficiency of power units and simplify operators' decision-making process.

For present-day facilities of increased danger, such time-related performance measures as delays in control actions transmission and emergency signals presentation are critical. Taking into consideration the appropriate control systems, one can note that the knowledge of arrival processes is necessary for the assessment of such delays. A couple of significant branches of applied mathematics: queueing theory and a theory of deterministic queuing systems network calculus operate with arrival processes and can help with delay evaluation. Arrival curves, a representation of arrival processes in network calculus, seem to be much easier to handle and obtain than probability distributions used in queueing theory. Nevertheless, many different arrival curves can be distinguished, each of them having its pros and cons. The article considers the problem of arrival curve representation and calculation for facilities of increased danger. It discloses the duality of the concept of arrival curve and investigates different types of them: the classical minimal arrival curve, the empirical one, linear arrival curves based on the empirical ones, and arrival curves on finite intervals. For the empirical arrival curve, the algorithm is presented, and the drawbacks are revealed. The advantages and disadvantages of empirical-based linear arrival curves are pointed out. The concept of arrival curves on finite intervals is considered, and the linear representation of them is highlighted. The algorithm for the calculation of linear arrival curves on finite intervals is presented, and their advantages are discussed.

作者： Vitaly Promyslov Kirill Semenkov Laboratory of Distributed Information and Control Systems V.A. Trapeznikov Institute of Control Sciences of RAS Moscow Russia

The paper considers the problem of analyzing the characteristics of a digital control system as a black box based on the input and output flows characteristics. The Network calculus method is proposed as a system model. The method makes possible to describe the system as a set of deterministic constraints or arrival curve on the flow. The paper proposes to extend the Network Calculus for the case when the flow is described by more than two parameters and extend Network Calculus for multidimensional feature space. An example the feature space may be consist from a packet sequence number, packet size and packet arrival time. The multidimensional flow might be described in a framework of the Network Calculus by some multidimensional arrival cure used to compute boundaries on the flow behavior and characteristics. The proposed extension of the network Calculus makes possible to model a wider class of systems, for example, considering non-uniform data flows.
