The article is devoted to scientific analysis of grain-processing branch of Russian industry and the structure of management grain-processing holding and the process of forming of its budget and financial resources management
The article considers an approach to managing the production process in agriculture based on modeling and evaluation of added value chains. The work has proposed a scheme of links for the production chain of added value creation that contains source control and financing cash flow which comes first in the link of agricultural production, then produced products are supplied to the accumulator, and from there it sequentially passes through the links of the value chain of the cyclic processing facilities, from which finished products are marketed and the resulting revenue is directed to the source of funding and management. We have given mathematical descriptions of the movement of financial and material flows in the links of the developed value chain, and mathematical models for calculating the volume of material and financial flows are proposed. Financial flows were also investigated to compensate for the cost of converting material flows and their mathematical descriptions. The article obtains a mathematical model of the economic efficiency of the production process and proposes a mathematical model for calculating the minimum price for socially significant processing products
The article is devoted to analysis of integrated industrial systems activity and creation of production line model of integrated grain-processing industrial system. The scheme of material-financial streams in the integrated industrial system of wheat grain production and processing is offered.

Conditions in which the work of acoustic magnetic device
proceeds are complicated because of the number of
interconnections. Solving problems under such conditions
analytically is difficult because of many variables
and complexity of some dependencies. The article describes
the conditions in which the work of acoustic
magnetic device, designed for nonchemical treatment of
hydroponic solution, takes place. The criteria, establishing
the initial state of the chains, containing mutual inductance,
are analyzed. The work establishes the criteria
relating the physical parameters of the environment with
the output parameters of the device. The similarity of
conditions of heat transfer on the surface of the device is
provided, and the relation of the scale of temperature
and power lost when heating the ferrite and winding
machine is determined. The criterion of the heat transfer
process is defined. The criterion, determining the relation
of the environment temperature to the thermal
mode of the acoustic magnetic device, is defined. The
criterion of the conditions at the boundaries of the
system and cavitating liquid is determined. It is found,
that the cavitation area appears in the technological volume
of liquid at the work of acoustic magnetic device.
The criterial equation for geometric parameters of different
types and constructions of the acoustic magnetic device is defined. In accordance with the task based on
the third theorem of similarity, the group of criteria that
provides the similarity of the model to the proposed
original by all existing indicators, is selected
We discuss adaptation of mathematical model city road network equilibrium parameters. Cases of exploitation on city roads are considered as well.
Agricultural producers interested in marketing of raw materials, whereas processing companies are interested in the establishment of raw material zones, providing capacity utilization; therefore, the establishment of sustainable linkages between producers and processors of raw materials is an objective necessity. In the article, with the help of mathematical methods we examine the conditions of mutually beneficial economic relations between agricultural producers and processing enterprises. Mathematical model for estimating the profits of the company is built of the following conditions: producers sell processing plants raw materials, determined by the coefficient of the interest in the partnership at an agreed purchase price, and the remaining raw materials are processed, so they can sell their products independently. Profit of the processing plant is determined by the mathematical model. To describe the nonlinear market-based sales of goods from its retail price we used a hyperbolic demand function
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
In article approaches to elimination of jams on roads are considered. Necessary conditions of application of these approaches are considered.
There were opened out some methods of optimal land management decision making. There was
proposed a system of mathematic models
on coming out of optimal forms of arable land
usage. There was modeled a combinative method
of land usage with regard of objects’ insurance
and so on.
