METHODOLOGY OF OPTIMAL PLACEMENT OF TRADE NETWORK OBJECTS
05.13.18 Mathematical modeling, numerical methods and software complexes
DescriptionThe article outlines the idea of a methodology for locating distribution centers of a spatially distributed distribution network without restrictions on the territory. In the past fifteen years in Russia, the profitability of offices and retail space has been significantly higher than logistic complexes. At present, it is possible to talk about a change in the investment attractiveness of the segment of distribution centers and storage facilities. The method consists in solving three problems: determining the number of distribution centers that need to be placed using the method of comparing options; determination of the best locations for placement of distribution centers using the ant colony algorithm; identification of the best location from the previously determined ant colony algorithm using the penalty function method. This method of optimal placement of objects of a spatially distributed complex can be applied not only to the distribution network, but also to any transport company with distribution centers, for example, a logistics company, delivery services, etc.

08.00.13 Mathematical and instrumental methods of Economics
DescriptionThe problem of the optimal distribution of production tasks is one of the important problems of effective planning of processes associated with production at the enterprise. However, the classical approach to solving this problem becomes of little use when the individual stages of the production process are performed sequentially and in the case when it is necessary to take into account the structural features of the technological processes of the enterprise. Purpose of work: to develop a methodology for minimizing costs in the distribution of production tasks, taking into account the structural features of the technological processes of the enterprise. We built a multicriteria discrete optimization model for the distribution of production tasks according to the structure of production elements. One of the methods based on the proposed model is proposed, which allows to identify groups consisting of four elements in the production structure of the enterprise. The model is built using a network design which are pre-fractal graphs. The use of pre-fractal graphs allows you to naturally represent the structure of production and technological links of the elements of the production system of large enterprises. The results of the work is the developed effective methodology for solving the problem of the network distribution of production tasks, taking into account the structural features of technological processes at the enterprise, the economic effect of which is to minimize resource costs. Based on the constructed model, we can develop automated means of monitoring and managing the production processes of a company

06.01.01 General agriculture, crop production (agricultural sciences)
DescriptionThe work is devoted to studying the nature of the effect of various doses of the drug called "Regalis" on the formation of the vegetative and generative organs of apple plants. Years of research - 2016-2019 Field experiments were carried out in JSC company "Agrocomplex" named after N.I. Tkachev in the Vyselkovsky district. Plantations were laid in 2007. Planting pattern 4.0 × 1.0m., garden irrigated, with support. The soil of the site is ordinary carbonated black soil (chernozem), the thickness of the humus layer is up to 120-140 cm. As a result of field and laboratory studies of the condition of 9-12 year old Gala apple trees grafted on P-59 rootstock, it was established that the annual treatment of apple trees for different phenophases with a preparation Regalis at a dose of 1.25 kg / ha has a significant effect on both the size and the number of vegetative and generative formations. It was determined that triple treatment of apple trees with regalis in 43.11% reduces the number of shoots longer than 60 cm, and double - by 31.39%. Structural changes in the distribution of vegetative and fruitful formations per 1 meter were noted in axial branches of the first order. Under the influence of the drug, the number of full-fledged “closed” buds in 2017 increased by 88.8%, and in 2018 by 70.9% compared with the control. The use of triple treatment with Regalis significantly reduces growth activity and has a positive effect on the passage of organogenesis of apple flower buds

FATTENING QUALITIES AND MEAT PRODUCTIVITY OF SALSKAYA SHEEP BREED OF IMPROVED GENOTYPES
DescriptionImprovement of domestic breeds of Merino sheep remains an important task. The reorientation of the industry to wool-meat and meat-wool direction of productivity can contribute to the restoration of domestic sheep breeding. An example of such conversion is a relatively young breed called Dzhalginsky Merino, created in the Stavropol region on the basis of the Stavropol breed with the involvement of resources of domestic and world breeding. In the current situation, it seems relevant to use Dzhalginsky Merino, in order to improve the meat and wool qualities of sheep of domestic fine-wool breeds. Obtaining a new genetic combination of animals, formed by combining the genotypes of breeds Salsky, Stavropol and Dzhalginsky Merino will increase the efficiency of the industry in a market economy and will provide a more complete use of the productive potential of the breed. The results of studies on obtaining and use of animals, new genetic combinations of a wool – meat direction of productivity, with high energy of growth, meat and wool productivity, improves the efficiency of Merino sheep are an important theoretical justification for making a contribution to zootechnical science, with the aim of improving fine-wool breeds of sheep and can be used in practical work in the production of high quality lamb

PROSPECTS OF APPLICATION OF LASER SURFACING AT RESTORATION OF DETAILS OF AGRICULTURAL MACHINERY
05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
DescriptionThe main component of agricultural production is machinery, which is a complex technical system (harvesters, agricultural machines, tractors, cars, etc.). The practice of operation of technically complex machines shows that, in general, the process of replacing worn parts and working devices of agricultural machinery with new ones prevails, and the number of restored products is small. However, experience shows that the technological process of restoration of machine parts allows you to get high quality surfaces of such parts and reduce the cost of repair. One of effective methods of restoration of surface layers of details is gas-flame spraying with the subsequent laser reflow. The article presents the results of the study of the zone of thermal influence in steels U8A and St3, as well as the influence of laser reflow regimes on its microhardness in these steels. It is established that the higher the laser power and the lower the speed of movement of the optical head, the larger the size of the thermal influence zone. Conversely, the lower the power of the laser and the higher the speed of movement of the head, the smaller the size of the zone of thermal influence. The power of the laser and the speed of movement of the optical head slightly affect the value of microhardness. It was also noted that promising areas in the field of restoration of parts of agricultural machines laser welding are: a scientific rationale for the selection of powders; the study of regularities of changes of the microstructure parts, regularities of formation of layers; development of modes and justification of regimes of welding; and, ultimately, the development process of restoring the specific parts

PROSPECTS FOR THE DEVELOPMENT OF URBAN STREET ROAD INFRASTRUCTURE
08.00.13 Mathematical and instrumental methods of Economics
DescriptionThe development of a city can go in two ways -extensive and intensive. Intensive involves a qualitative rethinking of the necessary work, optimization and improvement on the basis of existing infrastructure. An extensive method of development is an increase in physical volumes, for example, an increase in territories. At the moment, the transport system of the city of Krasnodar is extremely busy. The city occupies one of the first places in the number of vehicles, roads with such a traffic load can not cope, resulting in numerous congestion on the roads. In addition, an average of 150 thousand cars enter the city every day, and this creates an additional burden on the transport system. In the morning there is a large influx of cars from the main entrances to the city. And in the evening there is no less strong loading points of entry into the city, as those who arrived in the morning leave the city. Information technology is designed to save our time and effort. At the same time, one of the problems that "eats" time is traffic jams. You can get from one place to another at one time, but subject to traffic jams, this time can increase several times. Why not use technical and software tools to solve this problem!? Now almost everyone has a smartphone, with a Navigator loaded into it. There are many variations of these navigators with approximately the same functionality. But what if the Navigator in your smartphone not only chose the shortest path for you, but also helped in unloading traffic throughout the city, reducing traffic congestion to a minimum
