Modern distributed information systems (DIS), based on the complex application of many technologies, increasingly acquire the properties of multi-agent systems (MAS). Autonomy, mobility, cooperativity, intelligence, basic for MAS, become necessary properties of DIS. At the same time, the rapidly growing complexity, distribution and criticality of the use of DIS cause no less growth in the requirements for the reliability of their functioning, provided at the systemic, behavioral level by a complex of many approaches, both for project verification and for implementation testing. Most functional verification and testing problems have NP-complexity, which requires the integration of different verification tools and the use of various types of decomposition to achieve the desired result. The proposed model of MAS cooperation for testing is based on the representation of the behavior of DIS and MAS in their composition by extended Petri nets, automata behavioral experiments of check and recognition, functional hierarchical decomposition. The features of the model are the spatio-temporal decomposition of the set of events and actions of the goal and behavior of the MAS in the resource space of the DIS deployment environment, the spatio-temporal definition of the goals and behavior of all agents on the set of constrictions of events and actions of the MAS, the corresponding definition for agents of their autonomy, mobility, cooperativity and intelligence, the definition of cooperativity as a structure of agent coordination, the definition of the MAS model, reduced for events and actions outside the cooperativeness and coordination and commutation in its composition, the construction of a behavioral check model for the reduced MAS cooperation model. The proposed model is designed to reduce the computational complexity of behavioral check and recognition of cooperative interaction of the MAS and to determine the general algebraic conditions for constructing the corresponding

The structure of a multiloop system of fuzzy extreme control of modes and optimal stabilization of electric arc furnace coordinates using fuzzy inference systems has been substantiated. A method for calculating integral values of energy efficiency indices is proposed, using which performance curves of electric arc furnace were built.

This paper is devoted to increasing the automation level of docking operations through the development of a mobile application for a decision support system capable of determining the optimal option for loading ballast into floating dock compartments when setting up and launching ships. The proposed decision support system and the mobile application allow implementing effective ballasting of the floating dock before docking the ship based on mathematical calculations of the impact of the ship on the floating dock and the ballasting rules. To test the developed system, the paper presents the functioning of the mobile application for a case of calculation of the docking up process of a 4, 100-ton ship. In particular, the load forces of this ship are calculated with a graphical display of the distribution of the influence of 20 sections of the ship on 6 pontoons of the floating dock. As a result, this decision support system with the implemented mobile application has the characteristics of a convenient interface and is easy to operate. It can provide the dockmaster data and suggestions for decision-making, and during its operation, it is actively replenished with a database of the docked up ships. © 2024 River Publishers.

A modified approach to the Bayesian data analysis is proposed and an original methodology for identifying and accounting the possible uncertainties that exist in modelling and predicting non-stationary processes problems is developed. A new methodology for the combined model implementation is considered. It includes the following elements: the Bayesian data processing method, the optimal data processing filter, regression models for the statistical data formally describing and predicting the conditional variance, and the probabilistic Bayesian network model for predicting non-stationary processes. The conducted computational experiments for the financial market indicators forecasting showed that the quality of short-term volatility forecasts is significantly improved due to the optimal filtering procedure and the right choice of model structure. © 2020 IEEE.

Now we can see the rapid growth of the internet of things market, and low power wide area technologies have become very popular. Among these technologies, a long-range (LoRa) is one of the leading. The article discusses the features of the chirp signal that applied in LoRa technology under the conditions of multipath signal propagation, which takes place in densely populated areas, in a mine, high buildings, and other similar places. Multipath reception makes it difficult to process the true signal, so side signals are perceived as interfering. The paper analyzes the probability of symbol error and the bitrate under conditions equivalent to multipath propagation. The main feature of the presented work is a consideration of the case of signal propagation in the absence of direct beam propagation, i.e. Rayleigh's communication channel. When analyzing the parameters under study, the geometric representation of the received signals was essentially used. The obtained results are given in comparison with known approaches. © 2020 IEEE.

A procedure for formalized presentation of a sequence of test (verify) hypotheses in the course of checking the health of electronic devices when they are decomposed into subschema is developed. The procedure is brought to a practical algorithm that provides an effective (from the point of view of minimizing labor input) search for faulty subschemas of the electronic device.

This paper deals with the main features of electromagnetic interaction between the mobile robot's (MR) electromagnetic driver and ferromagnetic surface. In particular, the problems of clamping force calculation are discussed for robotic applications. The main attention is paid to computing of geometrical parameters of clamping forces localization patches by proposed combination-generation method. Efficiency of the method is checked by computer simulation and shown for one arc of localization patch's contour. Obtained results show rather high accuracy of this processing and its ability to be used in a functional structure of an experimental setup for fast Hall sensors' data stream computing at clamping force calculation by computerized tools.
