The analysis of activity of a sugar subcomplex has allowed to develop the specified schemes of re-structuring of the integrated industrial systems of the sugar subcomplex, the concept of interaction of objects of the integrated industrial systems of the sugar subcomplex, its information, monetary and material streams, and also to construct structure of the purposes and functions of a control system of the integrated industrial systems of the sugar subcomplex. The complex of mathematical models of costs estimation of using ground resources of the integrated industrial systems of the sugar subcomplex, the system of mathematical models of efficiency management of the integrated industrial systems of the sugar subcomplex and a quantitative technique of an estimation of activity of the integrated industrial systems of the sugar subcomplex are developed.
The article discusses the function of growth for the simulation of forest indices of individual tree element of the forest. Algorithm calculate tables of growth based on materials by eye-measuring taxation on the basis of patterns of variability of the amount of Room space of sections of stands of oak is proposed. Tables
of growth of stands of different density are developed
Plant growing successes influence the effectiveness not only the branch in itself, but the other branches
of agriculture, economics of agricultural enterprises
in whole as well. Models and methods of decision taking process improvement in plant growing were considered in the paper.
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 given developments are devoted to modeling of control systems by ecological safety of foundry manufacture. In a working zone of foundry shops except for a dust the significant amount of polluting substances is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The given dust is most dangerous to health of the working personnel and creates problems when clearing the air
Perturbed motion of a pole of the Earth caused by gravitational
action of celestial bodies is explored in the

The article studies the issues of drying, deformation and minimization of rice crack formation according to different parameters of drying modes
The simulation of the physical and mathematical model of the mounting mechanisms of a forest soil-tilling implement is developed. The model allows, on the basis of computer experiments, to determine op-timum geometrical parameters of the mounting mechanism
The article shows that the distribution of temperature regime in EIS corresponds to a known process of cutting and surface plastic deformation with heating details with acetylene-oxygen burner, which allows to combine the process of welding filler powders with finish-hardening treatment with combined instrument in the form of a two-pole bracket
In the article, the questions of modeling of the combined arable unit, in particular, in the process of rejection of soil by a lateral surface of rotational working body of active action are considered. Rational values of the parameters and operating modes of rotational working body of active action are received
