Authors: Mezentsev Y A , Baranova N V , Pavlov P S 
Published: November 2020

Abstract
The paper presents the problem of controlling the input and output material flows of an industrial enterprise, supplemented by the condition for the choice of sales prices and adjusted in terms of the number of products sold. This economic and mathematical model finds optimal solutions for the management problem at enterprises, namely, the problem of forming a production program according to the criterion of the maximum net profit at the end of the planning period. In the constraints of the model, both production components and constraints on resources and the logic of input and output material flows are systematically taken into account. The considered model and the given control problems are investigated using a unified approach that allows working with logical conditions of any complexity and setting the corresponding formal optimization problems. The results of testing the algorithm on test data close to industrial (real) dimensions are also given.

Published: November 2020

Abstract
The purpose of the work is to study the informativeness of visual models. The article reveals the features of the visual perception of images. We described the factors that distort the concept of informativeness as an objective value. The article proves that the perception of visual images cannot be equated with the collection of information using technical devices. We described the content of reception, perception and apperception in visual perception of visual models or spatial images The article introduces a systemic model of informativeness, which shows that the use of pixels as image elements does not evaluate the informativeness, but evaluate the information volume of the image. In order to evaluate the informativeness of visual models, it is recommended to use a visual cluster model. The article introduces a system of key indicators to evaluate the informativeness in the information visual processing.

Abstract
The paper deals with results of hardware-software complex application in nuclear power units design tasks and control. Critical analyses of existing information systems applied in the global power engineering was made. It was demonstrated that the main task, to be solved, was aimed at parameters monitoring and not processes control in complex. Moreover, all existing systems have distinguished functions resulting in high information load on operating personnel if there is no established managerial decision. Authors proposed the approach based on the power unit software model and respective mathematical simulation hardware for the operating personal support system development and nuclear power units facilities designing. A list of function for such systems was developed. It is demonstrated that the basis of functioning in technological process control tasks is the power unit simulation model enabling modelling under different operation modes. The power unit of the state-of-the art nuclear facility evolves a complicated technical system. For presentation of the power unit formal structure an oriented graph is used. Mathematical model of the power unit process flow diagram presents formalized record of the system digital and logic variables. The power unit model includes a distributed dynamic neutronics reactor core model, one dimension two-phase thermal physical model of processes in the main power unit systems, I&C model.

Authors: Korelin I , Porshnev S 
Published: November 2020

Abstract
Visitor flow dynamics at public venues has been studied by using mathematical models of the non-stationary queuing system and discrete-event modelling. Computational approach for research visitor flows quantitative characteristics is described. The dependence of input rate from time in non-stationary queuing system model is like the dependencies of rate of visitors to football matches. Quantitative characteristics are waiting line length and waiting time (time spend in queue) from time for different parameters of the input rate and the service rate device. It is proven that the maximum values of the studied characteristics and the corresponding time values are described by deterministic functions that depend on the maximum intensity of visitor flow and the average service speed. The form of these functions is well described.
An ultrawideband indoor positioning system with distributed ranging between tags
Authors: Krasnov T V 
Published: November 2020

Abstract
The aim of the work is to develop methodologies based on ultra-wideband positioning to create systems for the mutual positioning of moving objects. For this purpose, positioning errors in ultra-wideband radio navigation in the presence and absence of a direct signal propagation line between the radio tag of a mobile object and a base station are shown in the article. In presence of difficulties, pseudorange measurements acquire a displacement error. The construction of positioning systems using the ranges between radio tags (interpersonal channel) is proposed in the article. Construction of schemes based on radio channel models of copper mines shows that there is no error in the displacement of the RFID tag range, which is defined as the sum of the ranges by the intermediate RFID tag. With a low speed of movement of an intermediate RFID tag and a high frequency of range measurements, the intermediate marker can be represented as a fixed base station. The broadcast format of RFID signals will allow avoiding collisions on the air.

Abstract
In this paper, we present a study of web-crawlers behavior depending on the web resource. We provide a simulation model of web-crawler which is necessary for web robots detection techniques and dataset generation for methods based on machine learning. We analyze differences of behavior among humans, common crawlers, malicious crawlers and demonstrate that their models can be used for behavior analysis. We show that malicious crawlers behave similar to common crawlers and their behavior can be simulated to obtain necessary datasets and traffic patterns for the further detection and protection against unethical crawling. Our results and observations can be used as a basis of comprehensive intrusion detection and prevention system development.

Authors: Bekeneva Ya A , Petukhov V D , Frantsisko O Yu 
Published: November 2020

Abstract
In this paper an approach to local image processing in distributed monitoring systems is considered. The proposed approach makes possible to optimize traffic transmitted from monitoring devices generating images or video streams. Image processing, object recognition and identification are performed locally. Based on information received from all monitoring devices, including images, event logs are generated locally for their further transmission to the central data collection, processing and analysis unit. The method of local image processing was tested on the example of face recognition of people who took part in the experiment. Under various experimental conditions, it was found that the proposed method has a sufficiently high accuracy.

Authors: Korobko Aleksei A , Korobko Anna V 
Published: November 2020

Abstract
The effectiveness and validity of decisions in all subject areas depend on the completeness and reliability of the information base. Despite the development of information technology, some part of data is collected manually. This is important for the tasks of updating normative references, recording results of observations and laboratory studies, and statistical reporting. The paper describes the authors’ approach to building typical model-driven data collection systems. The approach includes the original conceptual model, the order of building systems by forming a control model and a set of algorithms for the construction of the system. Theoretical results form the basis of a software platform for building typical model-driven systems for collecting and consolidating primary data. The paper describes the procedure of constructing a data collection system on the basis of the platform using the example of the Soil Condition Research System. The software platform provides the systematization of consolidated data and their consistent storage. In addition, the control model of the system is a formal description of its subject area and may be useful for exploring the data collected.

Published: November 2020

Abstract
The work is devoted to the issues of building cohesive hybrid intelligent multi-agent systems that implement the following mechanisms for ensuring the joint work of heterogeneous agents: coordination of goals and agent ontologies, development of the problem solving protocol. These mechanisms are similar to the processes that occur in long-standing expert teams. In them, experts, interacting in the course of solving problems, exchange views, knowledge, take into account each other’s goals, establish formal and informal norms of communication. In the paper, in particular, a method for estimating the similarity of ontologies is considered, which is the part of the method for estimating the cohesion of agents of the hybrid intelligent multi-agent system. The estimation of cohesion is used by system’s agents as the interaction effectiveness criterion when making decisions about the need to converge goals, ontologies or correction of the interaction protocol.

Distribution law of the percolation threshold in one-dimensional bond problems
Authors: Yakunina T V , Udodov V N 
Published: November 2020

Abstract
A one-dimensional lattice percolation model is constructed for the bond problem at flowing along non-nearest neighbors. Arbitrary parameters were taken (percolation radius, number of nodes in a one-dimensional lattice and number of experiments). Based on original algorithms operating on a computer faster than standard ones, the values of the percolation threshold were obtained with the corresponding error. Based on these data, the hypothesis about the normal distribution of the percolation threshold is tested. Using Pearson’s criterion it was shown for the first time that there is no reason to reject this hypothesis for one-dimensional problems of bonds and sites with an arbitrary percolation radius.
New information technologies in the analysis of electroencephalograms
Authors: Eskov V M , Filatov M A , Grigorenko V V , Pavlyk A V 
Published: November 2020

Abstract
Today, the evidence of the Eskov–Zinchenko effect is becoming increasingly widespread. In this case, it is proved that any set of human body parameters is unique (statistically unique). Now we are also applying this effect to the neural networks of the brain. An analysis of electroencephalograms shows that brain biopotentials are not statistically stable. For the electroencephalograms analysis, it is proposed to create paired sample comparison matrices and find numbers k of the sample pairs that can have one (common) general population. It was found that these numbers k depend on the physiological state of the test subject. For example, for epileptic patients, number k increases dramatically, and it usually does not exceed 30-45% of all 105 pairs in each of such paired comparison matrices.

Published: November 2020

Abstract
We compare the results of splitting batches of industrial products (semiconductor devices) into several prospective homogeneous production batches using the standard k-means and p-median clustering models with various normalization methods. In the case of clustering problems, quadratic Euclidean distances are the most popular. We use them as well as the Mahalanobis distances to calculate the differences (distances) in the normalized space of the industrial product features, and compare the clustering results with the use of the Rand index, and empirically establish the advantage of the p-median model.
