The article presents the main directions of the
application of the scree plot method in solving
metrological problems in the social and humanitarian
fields of knowledge (economics, pedagogy, sociology,
including sciencemetry). It is known that statistical
measurements in socio-economic systems are
inextricably linked with the processing of primary
homogeneous monitoring information. It is also known
that empirical averaging (computation of the empirical
mean), as the dominant method of mathematical
statistics, is becoming a thing of the past, due to moral
aging, inconsistency with modern requirements
(primarily to measurement results in socio-economic
systems); In science meteorology, this method was
replaced by the scree plot method (the Hirsch index
and other scientometric indicators are estimated on the
basis of this method). Despite its enormous potential,
the scree plot method, as an alternative to traditional
methods of mathematical statistics, is very poorly used
in the social and humanitarian fields of knowledge.
The authors of this article have shown that this method
can be successfully applied in solving various
metrological tasks, not only in science (sciencemetry is
a branch of science), but also in economics, pedagogy
and sociology. In addition, the authors show
modifications of the scree plot method, using the
example of measuring (measuring) indicators in the
economy, sociology and pedagogy; The relationship
between the scree plot method and the theory of latent
variables (qualimetry) and database technology is
grounded. The authors also substantiate that the scree
plot method - the basis for the formation of monitoring
indicators that adequately reflect the performance of
socio-economic systems. The practical significance of
the results of this study is that they can be used in
socio-economic and psychological-pedagogical
monitoring systems (according to modern views,
monitoring is an information management
mechanism). Methodological basis of the research:
system, sociological, competence, probabilitystatistical
and qualimetric approaches (leading
methodological basis is the probabilistic-statistical
approach). Research methods: modeling; Methods of
graph theory, sets and relations; Systemic-cognitive
analysis; Methods of qualimetry (the theory of latent
variables); Methods of mathematical statistics
The article compares various hypotheses that explain the mechanisms of the influence of the magnetic field with different characteristics on liquids, physico-chemical and biological systems. Physical effects that cause specific biological activity of water (magnetic treatment of water, production of thawed water, degassing, etc.) make water be metastable or non-equilibrium states. Water attracts the attention of researchers as a likely universal mediator in the transmission of electromagnetic field signals to the biological level. Water is involved in a variety of chemical and metabolic reactions, so the question about the ability to change the properties of water and solutions under the influence of fields of different nature: an electromagnetic field with different frequencies, with different combinations of field orientations (parallel constant and variable magnetic field, slope fields, rotating magnetic fields, magnetic fields close to zero and electric fields) arises. At the heart of existing methods for treating liquids lie methods that use the energy of the acoustic and magnetic fields, as well as complex methods of influencing the electromagnetic field in combination with thermal heating, pressure change, etc. The analysis of existing hypotheses about the mechanisms of the influences of fields of a different nature on the treated liquid makes it possible to put forward a hypothesis about the possibility of the joint influence of the acoustic and magnetic fields on the liquid by means of the acoustic and magnetic device
The integration of producers of raw materials and its processors into the agro-industrial complex is connected with the social division of labor, its specialization, the need for interaction between specialized branches and types of agro-industrial production. Agrarian enterprises are united in an effort to reduce the risk, the emergence of which depends on the climatic conditions, the spontaneity of the agricultural market, the dictates of processing enterprises, the need to increase the competitiveness of production. In the Russian practice, there were various organizational forms of integration, differing in the nature of economic ties between participants, the degree of independence of the enterprises entering the association, the combination of centralization and decentralization of management. Conventionally they are divided into associative - "soft" and corporate - "hard." The "soft" forms of association include as-association, union, non-profit partnership and strategic alliance. They can effectively function at the interregional level. A rigid type of integration ties is characteristic for combines, concerns, trusts, holdings. Agricultural consumer cooperatives are voluntary associations of legal entities and individuals residing or operating in a certain rural area on the basis of membership and pooling of money units in order to meet the needs of members in credit resources and other banks services. The conditions for the emergence of sustainable integrated associations in the agroindustrial complex require qualitative and quantitative analysis based on mathematical modeling
The article proposes a solution to one of the problems
of small business, which is creation of a part of the
software of management of information system
efficiency for small processing enterprises of AIC.
The fact is, that currently, there are almost no
information systems to support small business. All
known information systems have approximately the
same list of automated functions, covering the
accounting phase, and sometimes phase of analysis.
Practically, not affected by the evaluation function of
the economic situation, prediction, planning and
regulation. The proposed mathematical model has
been developed on the basis of the creation of
streaming schemes of one-product processing
enterprises of agroindustrial complex and
mathematical description of the proceeding financial
and material flows

The article describes the process of developing the
two-level technique for assessment of the missed
benefit during the landing and cultivation of perennial
plantings. The technique is developed for the
enterprises where the cycle of production of raw
materials breaks into several periods until the first
harvest. The choice problem of the most suitable
grades for the landing is relevant for such enterprises.
The first level of the two-level technique assumes
assessment of qualitative and quantitative
characteristics of grades with use of such tools as the
theory of fuzzy sets and the decisions tree. The results
of the first level are entrance data for the second level
where there is final assessment of a grade and
determination of the missed benefit rather potentially
possible at the choice of the recommended grade. In
the article also designated the importance of the raw
materials stage for the technological chain. It is shown
that, being consecutive structure, the technological
chain strongly depends on the first stage – a stage of
raw materials production. Minimization of the risk
situations at the first stage promotes strengthening of
the general risk tolerance of a technological chain
The article reflects the relationship between the
parameters of research activities of students and the
characteristics of the educational environment in
higher education. It is known that the research activity
of students is an integral part of the educational
process, therefore, the parameters of research activity
can and should be indicator variables reflecting certain
aspects of the educational environment. According to
modern views, all types of research activities of
students (educational, research, scientific and practical
and research) is the most important mechanism for the
development of their research competence. In addition,
the parameters of research activities of students - the
reflection of the relationship of scientific and
educational activities in higher education, and this -
one of the most important factors of competitiveness
of the educational environment. The authors
substantiate that the parameters reflecting the research
activity of students characterize, first of all, such
aspects of the educational environment as its intensity,
social activity, dominance, coherence, mobility,
stability, reliability and efficiency. This is due to the
fact that the research activity of students is a transdisciplinary
process that depends on the same factors
as the educational process as a whole and is
characterized by the same didactic goals (tasks) as the
educational process as a whole. In identifying the
relationship between the parameters of research
activities of students and the characteristics of the
educational environment, the authors also took into
account the relevance of such a task as ensuring
continuity between levels of continuing education. The
theoretical significance of the results of this study is
that they can be the basis for further scientific
understanding of the problems of the quality of
education and the effectiveness of educational
environments, the practical significance is that they
can be applied in the systems of socio-pedagogical and
psycho-pedagogical monitoring and the effectiveness
of the educational environment, as well as monitoring
the student's personal and professional development).
Methodological bases of research: system,
sociological, competence, probability-statistical and
qualimetric approaches (leading methodological basis -
competence approach). Research methods: modeling;
methods of graph theory, sets and relations; systemiccognitive
analysis; methods of qualimetry (theory of
latent variables); methods of mathematical statistics
(first of all - the method of rocky scree); methods of
the theory of limits
The performance indicators of a trading company in
physical and monetary terms is significantly affected
by the types and volumes of purchased and sold
products, and which she purchased suppliers and the
consumers sold. However, the solution to the problem
of choosing the rational range of products faces
considerable cost of computational and human
resources, and lack of baseline data, and in real
dimensions this problem has no solution. The paper
proposes such a solution is very economical in costs of
different types of resources based on the application of
information theory, cognitive and control theory
Production and processing of grains formed in the national economic system of the country a number of cereals-governmental sectors, such as grain production, grain elevator industry, flour, cereals and mixed fodder production, which constitute the grain complex country. The significance and role of the grain as a commodity in the state economy can not be overestimated. This product is totally liquid, which has a constant, steady demand at any time of the year, in any region. Ongoing measures to increase grain production and improve its implementation did not have a complex character, therefore, insignificant effect on the efficiency of the industry and the competitiveness of grain production. The shortage was covered by imports. According to the characteristics of management in agriculture, it should be emphasized that the absence of objective and timely information at all stages of production of the plant-breeding, and as a result, non-optimal choice of technology of cultivation of agricultural crops, might result in the fact that the cost of labor and material resources increases significantly, the company does not receive profits, and sometimes suffers losses. When selecting cultivation technology for agricultural crops, an agronomist has a database of more than a hundred times-personal of alternative technologies for each crop. It is up to the decision-maker (DMP) to find specific criteria to select the most suitable (for the owners and the climatic zone) technology of cultivating for the culture. These circumstances explain the relevance of in-depth research of economic and mathematical models and methods of analysis and evaluation of the economic efficiency of technologies of cultivation agricultural crops. The article deals with the process of developing a complex of mathematical models and methods for evaluating alternative technologies for agricultural production (using the example of crop production), their software implementation, and the main scientific results of the project
The article presents innovative models and methods to diagnose the researcher’s synergic interaction with the scientific community (social mega-environment). It is known that the researcher’s interaction with the social mega-environment has two main directions: scientific collaboration and using the scientific community’s social and cultural potential; the former appears as scientific publications, while the latter appears as scientific citations. It is also known that synergic interaction is the interaction leading to the increase in activity results (according to the “1+1>2” scheme). In the article, the researcher’s synergic interaction is understood as his/her collaboration-based research activity that leads to obtaining the results impossible without this interaction. The theoretical significance of the research results is in the possibility for the further development of the sociology of science, as well as for the further development of the models of the individual’s interaction with the social environment; the practical significance is in the possibility to analyze the factors contributing to the success in the research activity of academic researchers and research teams (i.e. applicable for monitoring the research activity)
