Description
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

HISTORICAL TENDENCIES OF ECONOMIC GLOBALIZATION
DescriptionIn this work, prerequisites of processes of globalization of economies which source, according to authors, is the scientific and technological revolution of the XVIIIXIX century of century are considered. Dissemination of new technologies led to the international labor division, and emergence of information technologies promoted to increase in speed of communications, deleting of economic borders between the countries. A specific place in processes of globalization is held by space technologies by means of which there was a possibility of exchange of information between various consumers and the companies, which are in the different countries and continents. Based on the carriedout analysis, it is revealed that in the conditions of globalization pressure of group of industrially developed countries upon the rest of the world for the purpose of imposing of a certain model of their existence by the rest amplifies. The tool in competition are new technologies which help to drive the national companies out of the local markets. A special role in the course of globalization is played by information and space technologies of communication and broadcasting. Only competitive hi-tech productions focused on perspective technological ways can resist to influence of the international corporations. According to authors, distribution of innovative technologies has to contribute to the uniform development of all countries, formation of the multipolar world, the excluding domination of any country or the international group

EFFICIENCY OF THE FERTILIZER SYSTEM IN THE TECHNOLOGY OF EMPOWERMENT OF WINTER WHEAT
06.00.00 Agricultural sciences
DescriptionWinter wheat is very demanding on the nutrient regime of the soil. Like many winter crops, it consumes the nutrients unevenly distributed during the vegetation period, which must be considered when making them. Modern varieties of winter wheat are very demanding to soil fertility. For the formation of 4,0-4,5 t/ha requires about 140 kg of nitrogen, 50 kg phosphorus and 120 kg potassium. Therefore, without the use of fertilizers, it is not possible to obtain such a crop with high grain quality. In addition, in the cultivation of winter wheat in the high and intensive technologies simply need using large amounts of fertilizer to compensate for the removal of nutrients. This is especially important when having partial or complete reduction of application of organic fertilizers. Therefore, we consider the possibility and the results of studies using different doses, combinations and types of fertilizers in technology of winter wheat cultivation. Experimental studies were carried out in the conditions of insufficient and unstable moistening of southern zone of Rostov region, on experimental fields of the federal state scientific institution «ASС «Donskoy». For research, we have chosen the most common varieties of winter wheat (Tanais, Granite, Axinite, Terra, Donskoy prostor, Motto) and various combinations and combinations of mineral and organic fertilizers. The experiments were conducted on two predecessors: couples and peas. As the controllable parameters we had the productivity and quality of winter wheat. We have found a positive impact of the in-change of fertilizer on the studied parameters with a share of the variance of 96% and a high degree of correlation of 0,98. The marked increase in the productivity of winter wheat is up to 22% when using different versions of the experiment. We have identified rational combination doses of mineral and organic nutrition for predecessors: peas N40P60K40+2N30 and vapor – manure 40t/ha+2Р60+2N30

Description
Most of the tasks of planning and organizing transport routes are pointed to solving optimization problems on graphs in multi-criteria statements, for which the only optimal solution is missing. In conditions of multicriteria, it becomes necessary to search for a set of alternatives instead of an optimum. The quality of the admissible solutions is estimated by the vector objective function. The article proposes to investigate the problem using a special class of graphs - prefractal graphs, which allow describing in a natural way the structure of the hierarchy of territorial links, as well as enable to take into account structural dynamics in terms of system growth. A multicriteria mathematical formulation of the problem of covering a prefractal graph by simple intersecting chains is constructed, to which the investigated problem of organizing routes in large-scale transport networks reduces. The main social and economic requirements for the transport system are formulated and included in the model in the form of criteria

Description
Considering the pluralistic nature of the process of interpreting modern theorists of individual elements of economic reality, the main purpose of this article manifests the need to clarify the integrity and uniformity of approach to objective reflection of the realities of the economy. The basis for study in this work selected the category is "cost-permanent", an example of which is shown differentiation theoretical-economists views, that in the opinion of the author makes it difficult to harmonize the interpretations of the economic system, and therefore the subject of the article is of particular relevance. To prove the existence of a dichotomy of views within the scientific article analyzes the general population sources of theories about the nature of persistence fixed costs and based on exploitation mathematical and statistical apparatus disclosed each side of the existing concepts. Assuming that high-quality and reliable information on the level of management activities - the key to making competent and reasonable management decisions, according to the analysis to overcome the distortion of the generated objectification developed an integrated approach to understanding the category of fixed costs. The integral approach is argued by the admissibility of the existence of several points of view and the possibility of reducing them to one, which is the scientific novelty of the work

Description
The work is done in scientific and practical directions for minimization of power losses in transmission of electricity to local distribution networks between the actors of the energy (producers and consumers) of energy-saving technologies focused on technological activities such as modernization and reconstruction of networks. Quite often in various circuits of power systems, it is advisable to transfer energy and its power through intermediate (transit) nodes. Structural changes in the electricity sector, at present, are mainly associated with the introduction of market relations between the subjects of energy exchange; therefore, in this work special attention is paid to the problem of calculating the power losses, as it is nonlinearly dependent on the power at the nodes and branches of a network. It should be noted that the nodes in problems transit capacity could be both sources and consumers. The latter necessitated the need for search of possible ways to reduce transportation losses of energy due to both the improvement and optimization of distribution networks and through the use of intermediate transit nodes. It follows that the transportation problem in this formulation is more General and expands the possibilities of optimization of power losses for the local subsystems of the energy clusters. The work is composed of the transport matrix for solving problems transit capacity, where the algorithm taking into account the distinctive features of which consist in the use of continuous numbering of sources and consumers in the matrix, and any node can be a transit country. The transit capacity ii-th node Zii=0, and the dimension of the matrix in contrast to the previously considered tasks has (n+m) (n+m) and it remains square as all the transport problems of linear programming. Transit variables Xii are included in the solution of the problem with a minus sign, and all transit variables are considered basic. From the above example in the work of a number of branches of a network is minimal, which significantly reduces the cost of building and maintaining the network, and the solver minimizes the power loss between the subjects of energy exchange and, as a result to savings from the standpoint of cost of construction of the network and the management of overflows of energy in it
