  • Automation and control of technological processes of a promising checkpoint

    The restraining setting for customs administration at the border of the Russian Federation is the insufficient equipment and technological equipment of checkpoints. The current uniform requirements for equipment and material and technical equipment of buildings, premises and pass structures do not provide for the introduction of high new technological solutions that have appeared in recent years. Proposals are presented to improve the control system at checkpoints based on advanced technologies of Technet technologies and subtechnologies of end-to-end digital technology "Artificial Intelligence and Neurotechnologies".

  • A model for assessing the timeliness and completeness of the exchange of information resources in corporate systems with a distributed registry

    The article considers a model for evaluating the performance indicators of information resource exchange in corporate systems, designed to analyze the ability of systems with a distributed registry to ensure the timeliness and completeness of information exchange. As the main indicator, it is proposed to take into account the probability of failure of a segment of the corporate system for each epoch. To find this indicator, we use probabilistic estimates of sums bounded from above by hypergeometric and binomial distributions with probability boundaries of Chebyshev, Heffding, and Schwatal. A numerical and comparative analysis of the proposed estimates is carried out.

  • Methodology for ensuring the timeliness and completeness of the exchange of information resources in corporate networks with a distributed registry

    The article discusses the methodology for ensuring the timeliness and completeness of the exchange of information resources in corporate networks built on the basis of distributed registry technology, which takes into account the variability of the strategy of the behavior of the distributed registry system during information exchange. The technique takes into account non-standard functions, such as the formation of a branch of the processed data and the impact of an attacker, and also allows you to determine the average value of the block generation delay time by adjusting the number of operations required to solve the block. The use of this method allows to increase the value of the indicator of timeliness and completeness of the exchange of information resources in the corporate network by 30% compared to the existing system of information exchange.

  • Research of the difference model of coordination of public and private interests of resource allocation in marketing networks by simulation methods

    The article deals with the difference model of coordination of general and private interests in the distribution of resources in marketing networks. The dynamics of a managed system describes the interaction of members of the target audience (base agents), leading to a change in their opinions (spending on the purchase of goods and services of firms competing in a certain market). The gain of each firm includes two components: the total opinion of the base agents, taking into account marketing costs (the common interest for all agents of influence) and the return on investment in some private activity. The Coordinating Center determines the marketing budgets of the firms and maximizes the total opinion of the base agents, taking into account the resources allocated to the firms. The total discounted income of the Center and the agents of influence are found. The results are analyzed and the optimal allocation of resources is concluded.

  • Research of methods of loading of bales of biomass

    This study shows how it is possible to reduce the cost of transporting bales of biomass from the place of their production – the field, to the place of storage and processing on farms. The developed model of increasing the number of small warehouses allows farmers to transport round bales to storage locations in the most efficient way. The calculation was carried out in a field with an area of 16 hectares, the optimal distance for transporting bales is 0.8 km.

  • Algorithm for conceptual design of an object monitoring system with a collaborative multi-agent robotic system

    The issues of modeling the interaction of humans and robots in a common operating environment are considered in order to select the optimal parameters of such a system. The context of the application of multi-agent robotic systems (MRTS) is the monitoring of a fire hazardous area. The homogeneous MRTS includes unmanned aerial vehicles (UAVs) that cyclically perform operations of flying around their area of ​​the territory (with identification of fires) in an autonomous mode, returning to the charging base, waiting for charging, charging, returning to their area of ​​responsibility, flying around their area, etc. etc. An operator works in the charging area, to which the UAVs should not approach less than a certain distance. The system is presented as a multi-channel queuing system (in the charging area). A simulation model is constructed that allows, according to the data of many runs, to construct polynomial regression dependences of the quality indicators of the MRTS operation on its parameters, by which to solve the multicriteria problem of choosing the optimal parameters of the MRTS charging terminal.

  • Improving the economic efficiency of conducting cost expertise in the restoration of real estate after a fire

    The article deals with the forecasting of direct material damage to urban areas depending on the number of fires based on official data of the Ministry of Civil Defense, Emergencies and Elimination of Consequences of Natural Disasters, presented in state reports on the state of protection of the population and territories of the Russian Federation from natural and man-made emergencies for five years, based on the model of correlation analysis, which allows us to determine the degree of mutual influence of the parameters under consideration and the linear regression responsible for determining trends for subsequent years. The analysis of the reasons associated with the lack of the possibility of assessing the damage resulting from the fire of the structures of the building or its premises and its subsequent extinguishing in order to increase the economic efficiency of the cost examination during the restoration of real estate is an auxiliary basis for the construction of a correlation-regressive forecasting model.
