Discusses the relevance of developing a system of support of decision-making to build individual development programs for children with disabilities on the basis of criterion of assessment of disability in institutions of medico-social examination. The most important condition for achieving high quality examination is the use of scientific methods of system theory and qualimetry, formal approaches based on the use of problem-oriented software in the form of system of support of decision-making. The article formulates the requirements to the structure and functionality of the system of support of decision-making, focuses on mathematical apparatus, on the basis of which calculated the integral index characterizing an individual medical-social-educational development indicator (training) of a child with disabilities. Visualization tools allow you to build a profile that contains the quantitative characteristic for each criterion. The selection conditions of an individual trajectory of development and education of the child are formulated in the form of production rules, allowing you to make an individual plan of study. Also the system of support of decision-making is entrusted the task of monitoring the achievements of targets of the development and learning of the child. To exercise control it is necessary to organize the re-examination at every stage of learning and to compare the current profile with an initial or previous profile, compiled by the examination. The result of the comparison is the adjustment of the individual program of training and development. The use of formal methods, in the form of software tools provide a well-grounded choice of individual educational trajectories of students with disabilities and contribute to achieving the goal of quality inclusive education in accordance with Federal state educational standard of General education students with disabilities (HIA)
Keywords: psychology and pedagogical profile of the child, examination, decision-making support.
MODELING OF THE EFFECT OF ANTENNA ELEMENTS ARRANGEMENT INACCURACY ON THE ERROR OF THE CORRELATION INTERFEROMETRIC DIRECTION FINDER
A.I. Panychev, A.V. Maksimov, A.A. Vaganova
The main sources of instrumental errors of direction finding in means of automated radio monitoring are the design errors and the spread of the feeder path characteristics of the antenna system. In the article the direction finder realizing the principle of the correlation interferometric direction finder in which the resulting characteristic of the directionality of the ring antenna array is formed by the direct synthesis method is considered. The model of a volumetric array of linear radiators capable of taking arbitrary orientation and placed without shading each other is used. The distortions of the synthesized radiation pattern due to errors in the positioning of the antenna system elements along the azimuthal and radial coordinates are estimated. A comparative analysis of realizations of the synthesized radiation pattern of the direction finder obtained using various laws of distribution of geometric errors is carried out. Conclusions are made about the degree of influence of root-mean-square errors of antenna elements placement in azimuth and radius on the distortions of the radiation pattern. It is established that the displacement of the elements of the ring antenna array along the azimuth is more significant than radial displacement for deformation the radiation pattern. The main statistical characteristics of the direction-finding errors for both angular coordinates are calculated for different distribution laws for the errors in the placement of the elements of the antenna array. With a uniform distribution of placement errors, the hypothesis that a instrumental error in the azimuthal coordinate has a normal distribution is adopted in accordance with Pearson’s agreement criterion. In the case of a normal distribution of placement errors, the law of distribution of instrumental error in both coordinates is not normal.
Keywords: direction finder, annular array, radiation pattern, instrumental error, the direct synthesis method.
INFORMATION TECHNOLOGY OF DISTRIBUTION RESOURCES OF THE AUTOMATED MANAGEMENT SYSTEM OF MILITARY AND DOUBLE APPOINTMENT IN CONDITIONS OF INSUFFICIENCY OF INFORMATION ON THE DEVELOPMENT OF INTERFERENCE-TARGET SITUATION
D.O. Krikunov, V.A. Malyshev
The article considers the information technology of resource allocation for an automated military and dual-use control system in conditions of insufficient information on the development of noise-target conditions. The unpredictability of future interference effects and the possible change in objectives, the insecurity of domestic resources, as well as other almost unpredictable impacts, are called disturbances. Information technology is represented by a structural model in the form of a tuple of models performing certain narrowly directed functions on interaction with disturbances. The first model, included in the tuple, is the information model of possible perturbations, the second model describes the connections of the set of disturbances to the input of the automated control system, the third model converts the input object (disturbance) into an output object (control action), the fourth describes the connection of the output of the automated system with the set of disturbances, and the fifth set of reactions of the automated system to the appearance of each perturbation. Based on the technology of resource allocation for an automated military and dual-purpose control system under conditions of insufficient information on the development of the noise-target situation, an algorithm for its implementation has been constructed, including the consecutive implementation of five phases. Dedicated models due to the invariance of system properties are applicable to the description of the process of resource management of an automated control system at all levels of its organization.
Keywords: resource allocation, models, information, technology, automation, control systems.

USE AIS DATA FOR ESTIMATION OF MARINE TRAFFIC SAFETY
V.M. Grinyak, Y.S. Ivanenko
The paper is devoted to the problem of navigational safety of sea vessels traffic. The problem of determining the degree of danger of a traffic pattern implemented in a specific water area is considered. At the same time, it is proposed to refer to navigational data provided by the Automatic Identification System (AIS) and available on open Internet resources. As a metric characterizing traffic safety, the frequency of ship collision is used. It is determined on the basis of an estimate of the number and localization of closest points of approach. The problem with the use of AIS data provided by open Internet resources is a significant limitation in the accuracy of determining navigation parameters of vessels and the frequency of information receipt. The paper considers the format for presenting the initial data on motion and the available limitations. It is shown that, despite the limitations, it is possible to estimate a stable hazardous area of the waters. The work is accompanied by the results of case studies: the results of the estimation of marine traffic safety in the Tsugaru Strait, the waters of the port of Busan and the waters of the Inland Japan Sea are presented.
Keywords: vessel traffic control, collision avoidance, trace, closest point of approach, AIS.
APPLICATION OF THE WEAKLY-MANIPULATED GROUP PROCEDURE OF MAKING A CONSENSUAL DECISION TO INVEST IN THE STOCK MARKET
The article describes the procedure of interaction of decision-makers (DM) and the Council of experts under him who request for decision-makers develop and offer him a decision on the most effective investments in the stock market. The therapy is aimed at reducing the possibility of manipulating the decision-making process, both by individual experts and third parties through the use of special mechanisms of the theory of active systems together with the voting procedure and experience of the author. In addition, this procedure stimulates experts to offer the decision maker a quality solution, by offering him one of the best solutions out of many alternative solutions, members of the group. Another important advantage of this procedure is to support decision makers during decision-making due to the fact that the Council of experts invites the Centre to consider one solution. The proposed mechanism for making group decisions makes mandatory the use of quantitative criteria which sets the Center, which increases the transparency of the work of the Council of experts and the DM allows, firstly, better understand the process of developing collective decisions, and, secondly, if necessary, without quickly sort through the many alternatives on the specified criteria.
Keywords: non-manipulability, group decision making, agreeing common solutions.
HYBRID METHODS OF HIGH ACCURACY ORDER FOR NUMERICAL ANALYSIS IN THE TIME
DOMAIN OF STIFF AND OSCILLATING CIRCUITS
This paper considers the problems of numerical analysis of electronic circuits in the time domain that arise when using modern circuit simulators based on SPICE. Time-domain analysis of circuits through modern electronic simulators is realized by means of Gear’s methods and the trapezoidal method. An important property of models of real electronic circuits and especially of RF circuits is simultaneous stiffness and oscillability of these models. In turn, Gear’s methods can lose stability for oscillating circuits’ analysis, because these methods are not P-stable, and the trapezoidal method has a sufficiently high error for stiff circuits’ analysis, because it is not L-stable. The aim of this paper is to develop hybrid L- and P-stable methods based on the combination of various numerical methods for solving ordinary differential equations which provide a high accuracy of numerical simulation in the time domain of stiff and oscillating circuits. Hybrid methods are built on the basis of the known Rado IIA and Lobatto IIIA methods, which are subclasses of implicit Runge-Kutta methods. Comparative analysis of the known methods and the proposed hybrid methods demonstrates high accuracy of the latter methods for time-domain simulation of stiff and oscillating circuits and systems. Hybrid methods are also effective for numerical solving differential-algebraic equations that describe arbitrary electrical circuits.
Keywords: time-domain simulation, stiff systems, oscillating circuits, implicit Runge–Kutta methods, accuracy, stability.
