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 shortagecovered 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 multicriteria economic-mathematical model of a comprehensive assessment of technology of cultivation of agricultural crops.
The article presents results of the study to assess the effectiveness of credit funds in interacting agricultural (AES) and processing (PP) agricultural enterprises. The conducted studies are a continuation of the scientific work on the development of mathematical models of interaction of the enterprises of the AES and PP, are shown in the articles [1, 2, 3]. This article presents the authors’ developed set of models of management of credit funds of interacting enterprises of an agroindustrial complex. It includes mathematical models of economic efficiency of agricultural enterprises considering the use of loan funds, as well as the assessment of the maximum amount of interest rate of the loan and the minimum selling prices of units of finished agricultural products; a mathematical model of the economic efficiency of the processing plant taking into account credit obligations of the agricultural enterprise and a model for the calculation of the minimum selling prices of its finished products; a mathematical model of the economic efficiency of the combined entity with all its loans. We have proposed a model to calculate the minimum selling prices of its finished products
In the article we have reflected a relationship between
the parameters of the research activities of scientific
and pedagogical collectives and the characteristics of
the educational environment in higher education. It is
known that the research activities of scientific and
pedagogical workers and teams - an integral part
functioning of the higher education institution (and
improving its efficiency is one of the most important
problems). The authors proved that parameters
reflecting research activity of scientific and
pedagogical higher education of institution employees
characterize the aspects of the educational
environment as its latitude, intensity, social activity,
coherence, mobility, stability, reliability and
efficiency. It is caused by the fact that the research
activities of scientific and pedagogical workers - a
multifaceted social and cultural phenomenon. The idea
of the diagnosis of the educational environment of a higher educational institution and its structural units,
based on an assessment of scientometric indicators
(criteria for research productivity), can be completely
suitable for international and Russian requirements:
the well-known Shanghai procedure shifts the
emphasis on the evaluation of various aspects of the
research activities in higher education; serious
attention to assessing the research activity focuses and
Russian technique diagnostic efficiency of higher
education institutions. This is logical and soundly: if
the educational environment of a higher educational
institution is not a center of science, then it cannot
have effectively and competitive graduates, because
Research and pedagogical staff - the governing factor
in the educational process. Based on previously
developed models of research activities in scientific
and pedagogical collectives, as well as on generally
accepted models of educational environments, the
authors have proposed a method for the diagnosis of
the educational environment, based on an assessment
of scientometric indicators - parameters reflecting the
impact of the research activities of scientific and
pedagogical workers. Obtained results may be the
theoretical basis for further scientific understanding of
the problem of increasing the productivity of research
activities in higher education, as well as problems -
increasing the competitiveness of educational
environments. The practical significance of the results
of this study - the possibility of their use in the system
of socio-pedagogical monitoring - monitoring of
productivity the research activities and effectiveness of
educational environments. Methods of investigation:
modeling, methods of the theory of sets and relations,
methods of probability theory and mathematical
statistics, methods of the theory of limits, methods of
linear algebra and analytic geometry, multi-parameter
analysis of the systems and methods of quality control
(latent variables theory). Methodological bases of
research: a systematic, metasystem, qualimetric,
sociological and probabilistic and statistical
approaches
The development of agro-industrial integration is an objective economic process involving, on the one hand, with the social division of labor and specialization, on the other - with the necessity of interaction between specialized sectors and modes of agricultural production. Agrarian enterprises come into this unification movement, seeking to reduce the risk, the occurrence of which is associated with the production depends on climatic conditions, natural agricultural products market, the dictates of the processing enterprises, the need to improve the competitiveness of production. Processing and service companies are also seeking to secure a stable income thanks to the raw material base, better use of raw materials, improving the quality of its products, decreasing the price and conquering markets. In most cases, the object is to integrate agriculture, and direct or indirect initiators often are non-agricultural plants and firms that concentrate the bulk of production and sales of AIC final product. As a result, the concentration of production results in savings on its scale, so-called technical-technological economy. Increased production expands beyond the optimal use of machinery and equipment. The more spread out are agricultural producers, so it is more difficult to realize their interests for scaling up. In the Russian practice we have developed a variety of organizational forms of integration differ in the nature of economic relations between the parties, the degree of independence of members of the business combination, the combination of centralization and decentralization. Conventionally, they are divided into associative - "soft" and corporate - "hard". By "soft" forms of association include associations, unions, non-profit partnership and a strategic alliance. They can function effectively at the interregional level. Hard type of integration ties characteristic of plants, corporations, trusts, holding companies. Agricultural credit consumer cooperatives (ACCC) is a voluntary association of individuals and legal entities residing or conducting their business activities in certain rural areas, on the basis of membership and monetary union shares in order to meet the needs of the members in the credit and other banking services
The article analyzes reasons that prevent the formation of stable and effective AIC associations of commodity businesses and processors of raw materials. Unbalanced process of the relationship between agricultural producers and processing plants have a negative impact on the economic situation of the organizations partners. Dictating low purchasing prices for raw materials by processing enterprises hinders profitability of agricultural producers. Purchase prices set by the processing enterprises of the dairy industry for milk, do not compensate for not only the production costs but also the losses from inflation. The rate of growth in energy prices is significantly higher than for livestock products, bringing its cost grew faster than sales prices. This leads to a dramatic reduction in milk production profitability. A paradoxical situation: on the one hand, dairies are facing an acute shortage of raw materials, on the other - exacerbated the problem of the sale of its milk producers at a reasonable price for them. The disparity between the purchasing prices for milk and retail prices for dairy products caused agricultural companies to seek alternative markets. Sharply increased sales of milk in the bottling of milk tankers, while many farms began to create their own recycling system
It is necessary to know exact value of the full
dispersion of waveguides, which leads to broadening
and reduction of pulse amplitude for modeling laser
radiation passage in quantum cryptography systems.
The operation purpose was obtaining of dependences
on a wavelength of various dispersion types according
to the Sellmeier’ sequationand optical pulse radiation
modelling in quantum communication systems.
Dependences of the material, waveguide and
chromatic dispersions on length of a wave according to
the Sellmeier’s equation which allows to consider an
optical fiber’s material are received. Distribution of a
cryptographic impulse through fiber-optical
communication lines of various extent is simulated
The analysis and assessment of risk at the macrolevel
in this context is understood as assessment of extent
of influence of the external environment (macro
environment) on activity of the integrated production
system. In the article the model and the technique of
calculation of an integrated indicator of risk of an
adverse effect of the external environment of the
agro-industrial integrated production system is
offered. All stages of creation of the model which
include representation of basic risk factors of
macrolevel in the form of linguistic variables are
described, each of basic risk factors is a compound
linguistic variable. For obtaining total value of a
basic factor the matrix scheme of aggregation of
compound factors to basic level is used. The
equation of model of an integrated indicator of risk
of an adverse effect of the external environment on
the integrated production system is presented. The
principle of recognition and interpretation of result
on the basis of standard fuzzy 01-classificators is
shown. Also in this article the interrelation of an
integrated indicator with the choice of the strategy of
development for business system by definition of a
condition of the external environment is shown, and
depending on it the strategic scenario of development
of business system is offered
In this article the model and a calculation procedure of
an integrated indicator of risk of the internal
environment of the integrated production system are
described. Then the steps of creation of triangular
fuzzy number for expected value of profit are given.
At creation of this fuzzy number the concept of an
indicator of risk of the internal environment of the
integrated production system was used. Further on the
basis of the developed model of internal risk the
interval model of efficiency of the integrated
production system is developed and described. In this
article the structure of a production chain of the
integrated production system of agroindustrial
complex was considered. In technologically complete
production chain, as a rule, allocate three stages – raw
materials production, storage and conversion, sale of
finished goods. Each subsequent stage depends from
previous stage, and at each stage various situations of
risk are shown. Also the process of risk identification
of the internal environment of the integrated
production system was considered in this article.
Process decomposition is executed, the description of subprocesses is given. For a risk assessment of the
internal environment it is necessary to know quantity
of production chains, and also to calculate value of risk
for each production chain on the enclosed algorithm.
Also in the article the principle of recognition and
interpretation of results of calculation of an integrated
indicator of risk of the internal environment of the
agro-industrial integrated production system on the
basis of Harrington's scale and standard indistinct 01
classificators is shown
In the work we have developed a structural modeling
of the optimal choice of information security devices
in the design of automated systems in the protected
execution in the transition to network centric methods
of control of troops and weapons
The article presents the new criteria suitable for the
diagnosis of the productivity of research and the
importance of its results for the scientific community, are resistant to artificially "improve". It is known that
generally accepted measure of the productivity of
research scientists is the h-index, which is calculated
based on a statistical method of scree. This indicator is
applicable to research teams (organizations). However,
the h-index and a number of other scientometric
indicators based on citation, are easy to be artificially
increased (fraudulent schemes action). New
scientometric parameters adequately reflecting the
importance of research results, and not amenable (or
very difficult to) to be artificially "improved" are
therefore needed; moreover, it is recognized around
the world: the true score (not fictitious) of the
significance of the results of a research scientist for the
scientific community - is a complex metrological
(scientometric) task. The authors argued that such
indicators are primarily index latitude demand for
research results, as well as a number of other
parameters of copyright. Despite the fact that authors
indicators, the same as the h-index are based on
citation, their large values indicate that the scientific
community recognizes the results of the research
activities of scientific and pedagogical workers;
moreover, these indicators can be considered as a
criterion to identify really promising (productive)
researchers. The problem of adequate assessment of
the productivity of research activities and the
significance of its results, the authors consider in the
context of the problems (larger problems) of the
effectiveness of educational environments. The
practical significance of research results lies in the
possibility of their use for constructing criteriondiagnostic
apparatus for monitoring research activities
of scientific institutions (including higher educational
institutions). Research methodology: systemic, metasystemic,
probabilistic-statistical and qualitative
approaches. Research methods: cognitive, structural,
functional, and mathematical modeling; methods of
graph theory, sets and relations; system-cognitive
analysis; methods of quality control (theory of latent
variables); methods of probability theory and
mathematical statistics (first of all – a method of
scree), methods of analytical geometry; methods of the
mathematical theory of limits
