The article suggests a mathematical model of optimization of the volume of material flows: the model for the ideal conditions; the model for the working conditions; generalized model of determining the optimal input parameters. These models optimize such parameters of inventory management in technology-integrated grain production systems, as the number of cycles supply, the volume of the source material and financial flows. The study was carried out on the example of the integrated system of production, processing and sales of wheat (bread) with the full technological cycle
Grain is of strategic importance and is the basis for
food security. The gross national product share of
grain and its products is about 10-15%. It always
stands out from other types of raw materials, as it is
used to produce the most popular daily foods. 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 adaptation and the possibility of using the
model and the method of binary matrices to solve the
problem of the choice for cropping technology
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 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
In the article, we present the analysis and improvement
of existing methodologies for assessing the
intelligence factor, taking into account its use of the
Internet on a regular basis. Today, the use of the
Internet in our daily activities and tasks become
practice that is more common. The Internet has
become a popular and most frequently used means of
obtaining information quickly and in large volume.
The authors suggested the presence of the Internet and
its impact on the everyday use of psychological and
intellectual life of the people that can be recorded
because of user IQ scores. It is suggested here also gets
its development in the search for and analysis of
system models, allowing determining the numerical
values of the parameters. Specifically, it is proposed to
use a large variety of statistical data to clarify the
unknown parameters that determine the levels of
human intelligence, taking into account the impact of
the Internet. These statistics include information such
as the number of people with higher education, the
number of Internet users, the degree of the Internet penetration in society, the most typical tasks that use
the Internet users, and others. For the processing and
analysis of the test statistics in the work proposed to
use tools data mining, ie, data mining. We have also
considered the most typical approaches Data mining,
applied in similar research areas. We have analyzed
what specific principles and methods can best
approach to solving the problems of intelligence
assessment indicators. The result of the article was a
number of conclusions, in particular, the feasibility of
applying clustering to analyze data in the field. Also,
in certain cases, we provided the use of Kohonen
neural network in the vector quantization network
format. Methods: analysis of scientific literature and
online sources of information on the current level in
the field of IQ research; modeling; Methods
systematization (tabular calculations and compilation);
Experiment (real human test data). Methodological
bases of research: a systematic approach (considering
IQ in the form of a functional multi-component
dependencies), probabilistic and statistical approach
(provides guidance for constructing mathematical
models linking together IQ and the influence exerted
on it using the Internet, and to assess the reliability of a
computer program ) qualimetric approach (determines
the need multicriterion diagnostic influence of factors
on the level of intelligence)
In this article we have presented the results of the
research of submission and evaluation of organizational structures of control systems based on the theory of mass service
The article discusses scale formation problems of greenhouse complexes with geothermal heat sources. Two-circuit geothermal heat supply systems with intermediate heat exchangers are used to prevent equipment and communications scale. Fresh softened water is heated by geothermal heat and is supplied to consumer needs. The heat exchanger and primary circuit communications contacting with the geothermal heat carrier (geothermal water) are subjected to scale formation in the existing system. A scale formation of heat exchange surfaces reduces the efficiency of the heat exchanger and requires a periodic cleaning and causes a chain of economic losses in the production, transportation and consumption of heat. Currently, we use physical, chemical, biological and combined methods of scale formation prevention. The article also considers hypothesis about the effect of an acoustic-magnetic field on solutions. It was found experimentally, that the acoustic-magnetic field affects to characteristics and dimensions of salt crystals. The number of particles increases and solid phase dimensions decrease. A large number of microcrystals suspended in water are formed as a result of the nonchemical acoustic-magnetic treatment of geothermal water. These crystals do not stick to the pipe surface and do not settle to the bottom, may be filtered out and carry out by water flow from the system
In the article we provide a survey of cryptographic systems on the basis of unjammable coding; we offer the aspect of codes with natural redundancy for the solution of a problem of simultaneous protection of the information and detection and correction of errors; the demonstration is resulted that codes with natural
redundancy are group codes
