This article provides results of studying the world
achievements in modeling social systems in the
aspects of personality, group, and social institute (e.g.
the state and army). Through prism of conflict, we
review research methodology for modeling social
identity, social navigation, geopolitical processes, and
command and control systems of the enemy. We
discuss four agent-based models of social identity:
SCIPR, MetaContrast, PS-I, and SILAS. We examine
Spence model for modeling social navigation. Basic
principles for modeling relations between the states
are considered using ontology approach. The
presented model allows systemic analysis of various
micro- (intrastate) and macrolevel (external) variables
and relations between them. Modeling command and
control system of the enemy is implemented as a part
of an automated decision support system that tackles
the problems of enemy structure identification as well
as classification of objects and relations within the
structures. The object of study are approaches,
methods and models for representation and analysis of
group interaction. The subject of study are processes
of agent self-identification and interaction, formal and
informal organizations, the states and public institutes
as well as processes and principles for group
formation and mechanisms for behavior control.
Research methodology: social network analysis,
ontology approach, theory of graphs and hypergraphs,
multiagent systems
In the article, we have calculated the cost of the combined energy of the proposed four types of the multifunctional units and their optimal system for the conditions of grain harvesting in the Krasnodar region; the analysis of the costs has also been reviewed
The article discusses the application of the theory of
vibration in the design and creation of devices seeding.
The ways of solving the problem of creating a single
universal device for seed and fertilizer using vibration
processes influencing the change flow rates when sowing
seed from the hopper. The ability to transfer the
balance of volume of crops and fertilizers at the expiry
of their bunker in order to bring the different flow rates
for identical simplifies management processes noncontact
sowing materials of different physical and mechanical

Modern extraction systems are characterized by a change in the parameters of the production cycle under the influence of a number of causes caused by the structural dynamics of systems. Information systems can successfully function by solving the tasks of collecting, processing, analyzing and distributing real-time information, which involves the use of modern information technology methods. With increasing requirements to the volume, speed and quality of information on the progress of extraction processes, modernization of information systems is required, allowing to make informed decisions by management structures. In the article the regularities of mass transfer of n-components in carbon dioxide of the solid-liquid system are considered. The effect of spontaneous interfacial convection in the mass transfer of individual components under the influence of an electromagnetic field of low frequency is detected. The joint mass transfer of extractive substances during spontaneous interfacial convection leads to an increase in the mass transfer coefficient of eugenol compared to its diffusion mass transfer
Hereby are represented: method and results of experimental research for substantiation of rational operating mode for honey centrifuge electric drive. Empiric model of influence of honey temperature (from 20 to 30 оС) and honey humidity (from 17 to 21%) on initial rotating speed of centrifuge was worked out. Rational operating mode of honey centrifuge electric drive consists of 3 stages of honey output. Rotating speed of drum with allowance to the honey temperature and humidity for each stage was substantiated. There is an example of model using. Recommendations for application of research results are given
The article shows the influence of pre-treatment
with a solution of sodium chloride and a solution of
succinic acid in various concentrations to clean the
baskets-of inflorescences of sunflower from the
ballast towards the pectin substances. The
application of these solutions helps to reduce
protein, coloring and aromatic substances contained
in baskets-inflorescences of sunflower, as well as
easing the connection of calcium ions with
protopectin in inflorescences of sunflower, in the
future, cleaned baskets-blossoms of the sunflower
are used as raw material for producing high-quality
pectin extract
The presented technique of optimizing adequacy and requirements feasibility for electronic component-component base includes expert evaluations method data requirements, as well as an algorithm of optimization and aims to support decision-making in the planning work area on capacity-electronic components
The article describes the methods of synthesis of optimal structural schematics of autonomous power supply systems, made using renewable energy sources, for several performance criteria
The article is devoted to an actual problem: increasing of reliability of expert estimates, due to attraction in group of the most competent experts for carrying out examination. The analysis of application of expert estimation in the field of operation of corporate and telecommunication networks is provided in the article. The technique of an assessment of competence of experts is offered. When assessing the competence of experts the following factors were considered: specialization of the expert, an experience and experience of its work in the field, scientific qualification, existence of scientific works on a perspective of carrying out examination. For identification of a priority of factors at determination of competence of experts it is offered to use a method of the analysis of hierarchies. The necessary number of experts for carrying out examination of objects is defined on the basis of application of the statistical analysis
The article presents an analysis of the existing approach
to automobiles technical maintenance in
agriculture. We have pointed out that in modern
conditions it is impossible to forecast the automobiles
maintenance operation frequency and as a
result its improvement as well. It is obvious that
one cannot achieve the considerable increase of
maintenance operation efficiency by separate means
and there exist the necessity to treat it as a system
and use the up-to-date methods to investigate and
improve complicated systems. We have made a
conclusion that the increase of maintenance operation
efficiency is not possible without some rational
strategy of maintenance operation and repair. We
have shown that the program of maintenance operation
and repair being an integral part of automobiles
technical maintenance has considerable effect on
maintenance and repair quality. As a result, there
is some necessity of the developed system of
parameters diagnosing and control in technical
maintenance and repair. We have shown that to
get sufficient diagnose information one needs
selection of the controlled parameters which
give maximum information about the object
technical status taking into account possible characteristics
of its operational faults. We have discovered
that in order to solve the task it is necessary to
have the object’s information pattern, calculation of
possible characteristics of the controlled object being
in good or bad order due to some parts fault,
evaluation of information brought by every parameter
and determining parameters to be diagnosed. We
have proposed to evaluate the parameters’ information
value with the help of information entropy as
uncertainty measure that is one of the main concepts
of the information theory. Because of solving
the task, we have got the aggregate of the controlled
automobile parameters orderable according to the
amount of information
