  • The method for the technical and economic assessment of options for building an organizational and technical system of the "cyberpolygon" class

    The article is devoted to the study of problematic issues of the formation of organizational and technical systems of the "cyberpolygons" class using the original methodological apparatus for the feasibility study of system engineering solutions for their construction. The features of existing approaches to the justification of system engineering solutions for the construction of organizational and technical systems, information technology and technical systems are considered. Directions for their development are proposed, taking into account the dynamics of the phased creation and modernization of organizational and technical systems with simultaneously developing infrastructure projects and solutions. Formal aspects in the methodological apparatus are reflected in the change in the composition of the functional components in the conceptual and analytical models, the corresponding formal descriptions of their relationships and characteristics, as well as in the modification of the procedures for the technical and economic assessment of options for building a cyberpolygon. The method of technical and economic evaluation of options for constructing a cyberpolygon proposed in this study makes it possible to rank alternative options for the infrastructures of the created cyberpolygon according to the value of their technical and economic efficiency and to select the rational one from them.

  • Organization of formal cognitive model processing schemes

    The article offers schemes and models that allow using formal parameters and procedures to expand the capabilities of cognitive modeling and increase the level of adequacy of decisions made based on the results of modeling. The paper presents various variants of modeling schemes, which allows the researcher to perform a more versatile analysis of the system, including the analysis of dynamic effects, as well as the selection of parameters of control actions that provide the desired level of system response.

  • Model of a dynamic neuron with state memory

    The problems of synthesis of a model of dynamic neuron with state memory (DNSM) are considered in the paper. The introduction of a special additional parameter into the model of a neuron, defined as a state parameter, is substantiated. It is indicated that the parameter of the state of the neuron has the ability to vary with time depending on the nature of the information processes that occur in neighboring neurons of the network. This parameter in a certain way accumulates information about the history of the behavior of the neuron in accordance with the entered formal descriptions. The concept of a "strained neuron" is introduced, taking into account the above. This concept characterizes the degree of influence of a given neuron on the neurons surrounding it. On the effects of time-varying parameters of the state of neurons, it is proposed to implement the process of self-evolution of the network directly during its operation. A variant of the analysis of the structure of the neural network, created on the basis of the proposed model DNSM. The topological representation of a neural network in the form of a graph model allows formalizing the interaction of neurons in a network with each other, both in time and in space. For this, the concept of k-space is introduced, which determines the degree of proximity of neurons to each other. The degree of proximity of neurons allows one to formalize, in the form of mathematical relationships, the procedure for the exchange of information between neighboring neurons in a network. Mathematical relationships that formalize these processes are given. A variant of the structure of the hardware design of DNSM, focused on implementation using FPGA technology, is proposed.

    The article considers a number of proposals aimed at improving the efficiency of the design, training and operation of neural network models within the framework of control systems for complex objects. This includes: organization of processing of networks of large dimenstionality; development of neuroevolutionary procedures; providing opportunities for the formation of neural network models in a single cycle of designing automated systems. The hierarchical construction of network structures is considered as an apparatus that provids work with network models of high dimensionality. At the same time, unlike the traditional approach associated with cutting the graph of an already synthesized model, the article proposes procedures for synthesizing a generalized model from structural elements. The formal descriptions of structural synthesis introduced in the article can serve as a basis for organizing software and hardware interfaces of the forming models. The formation of such neural network structures within control systems is associated with the proposed and described concept of neural network regulators as the basic elements of building intelligent automated systems. The article also examines and describes as a neuroelement a model of a dynamic neuron with a state memory, allowing to implement the mechanism of self-evolutionary development of the network directly in the course of its operation.
