The article deals with the complexity of the construction of engineering theories in both scientific and practical direction based on the use of non-traditional approach to the problems of effective data monitoring, especially in the field of control systems of multicomponent representation of objects of system analysis. The study of the complexity of this issue involves a detailed consideration of the relationships of the elements of these objects on the basis of known methods, while the integration of heterogeneous knowledge obtained by such often independent methods becomes very time-consuming and poorly formalized. Currently, the processing of information and its subsequent presentation have changed significantly through the use of data mining (IAD), which includes not only the organization of the knowledge system in various missile defense, but also in the field of DSS. This, in turn, contributes to the effective formalization of fuzzy information and processing it in the form of fuzzy algorithms, which is an extension of the decision support system based on fuzzy logic – DSS NL. At the same time, it is necessary to emphasize the features of the proposed approach of the DSS NL, which is that it can be used in various missile defense systems, including for the effective analysis of statistical information of multicomponent representation of objects, which is used in determining statistical indicators to identify and assess existing and potential risks, adverse situations, as well as in the preparation of motivational grounds for managerial decision-making. For the purpose of more detailed establishment in real missile defense of the relations between objects it is offered to carry out by means of various degrees of dependence. For example, the types of graded connections are considered as fuzzy objective connections, and the use of expert systems and semantic links led to the construction of hypotheses analysis of situations and semantic relationship between them. A significant difference of the considered DSS NL is that each model is formed on the basis of a separate semantic network, and the system itself works with several models of Pro related or unrelated to each other. On the basis of the use of the concept of the relationship of proximity between concepts, belonging to the situation, its information part of the recommendations Are grouped according to the selected situation for their subsequent analysis and decision-making. On the basis of the principle of coordinating actions and construction of the function, taking into account the optimal time of the control action, the General algorithm of decision support for emergency production situations in the Pro low-rise construction, both in urban and rural areas
Automation of productions is a necessary condition of reduction of losses for processing enterprises. Any automated system contains subsystems, each of which solves specific objectives, being at the same time accessory of all system. Therefore, when starting designing a system of acceptance and processing of raw materials, it is necessary to define the importance of result of the solution of each task for increase in efficiency of a production cycle. In the article we present results of expert polls of experts – wine makers for definition of problems of automation of processes in the plants of primary winemaking
The 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

In modern economic theory, there is no complete classification of innovative approaches to the management of knowledge-intensive and high-tech companies and enterprises. Among these approaches, we can highlight situational, structural, process, functional and project-based approaches. The project-oriented approach, as a purposeful method of future systems forming, is a kind of continuation of the process approach; however, it gives priority not to the process, but to the project, as the main production, innovation and competing business unit. This article provides a brief overview of carried out research in this subject area, analyzes the advantages and opportunities of existing project management validity models, and suggests the author's approach of building a model for identifying and evaluating the potential of modern project-oriented companies and enterprises. This article also shows that the economic efficiency of such companies and enterprises achieving by using the project-based method both in the integrated system of strategic management and in the main production activities. This leads to an increase in their ability to choose the right way of operational decision-making, contributes to the installation of advanced technological and technical equipment, and accelerates the commissioning of new production facilities
Progress in crop production depends on many factors; including the important measure is the protection from pathogenic microorganisms. Various chemicals are used to control phytopathogens, such as natural and artificially synthesized ones. Natural compounds are more environmentally friendly, in most cases less toxic and quickly destroyed. The purpose of this work was to find strains of actinobacteria that have antifungal activity and are considered by us as possible sources of antifungal compounds for agricultural purposes. We selected 10 strains of actinobacteria that were isolated from typical regions of Russia. These strains were active against the fungal test strains Saccharomyces cerevisiae RIA 259 and Aspergillus niger INA 00760 when deep cultured. To determine the activity of selected actinobacteria against phytopathogenic fungi, 6 strains isolated from affected plants were used as tests. Morphological and genetic analysis methods have shown that the selected actinobacteria strains belong to two genera and are represented by the following species: Nocardia soli, Streptomyces antibioticus, S. bottropensis, S. chartreusis, S. chromofuscus, S. hydrogenans (2 isolates), S. lusitanus, S. netropsis, S. peucetius. Phytopathogenic fungi are represented by the following species: Fusarium armeniacum (2 isolates), Fusarium culmorum, Alternaria tenuissima (2 isolates), Bipolaris sorokiniana. As a result, it was found that under conditions of submerged cultivation on nutrient media, actibacteria form substances that inhibit the growth of all phytopathogenic tests used in the experiment. The representatives of species N. soli INA 01217, S.chromofuscus INA 01211, S. lusitanus INA 01218, S. netropsis INA 01190 and S. peucetius INA 01255 have not been described as having antifungal activity previously, so we consider them to be the most promising for chemical research to identify new antifungal antibiotics
In the article, we develop the methodology of strategic planning and management of the holding on the theoretical basis of automated system-cognitive analysis (ASC-analysis). This methodology provides scientific research of any holding by creating and researching its model. The methodology includes both the synthesis, adaptation and verification of system-cognitive models of the holding, and the use of these models for strategic planning and decision support for managing the holding, as a complex, multiparametric, nonlinear system. The relevance of the research is due to the special role of holdings and other corporate integrated structures both in Russia as a whole and, in particular, in the Krasnodar region. Despite obvious system advantages, holdings face a wide range of problems related to management efficiency, ensuring their sustainable functioning, etc. The proposed methodology offers ways to solve these problems and can be successfully applied in holdings and other corporate integrated structures of various regions, volumes and areas of activity, which determines the relevance of the research topic. The level of significance and scientific novelty of the Research consists in the development of conceptual and theoretical and methodological provisions aimed at managing the development of holdings. The expected results and their significance are that the methodology developed as a result of the Research can be applied by holding companies and other corporate integrated structures and will significantly improve the quality of their management
Issues associated with the use of combined units in the preparation of the soil are relevant and of scientific and practical interest. Relevance increases when it comes to the cultivation of the main crop - winter wheat. In this regard, the presented results on the effectiveness of the use of combined units in the preparation of soil for winter crops are important. They are important primarily from a practical point of view. Experimental studies were conducted in the conditions of many years of stationary experience in the FSUE "ANC" Donskoy ", Zernograd, Rostov Region and in the Krasnodar region, LLC "Step". The efficiency of the use of combined units KUM-4, APK-4, developed at SKNIIMESH, now FSUE “ANC “Donskoy” in the cultivation of winter barley and winter wheat is considered. The technological process of tillage using combined units consists of several technological operations performed simultaneously. Disk working bodies chop plant residues and destroy weeds. At the same time, a network of cracks in the underlying soil horizons is laid. Next are flat-cutting working bodies that loosen the soil already at the set depth. There is a cutting of the root system of weeds, loosening the remaining non-loosened soil layer to the required depth, the formation of a flat bottom of the “furrow”, the separation of erosion-hazardous soil particles to the bottom of the furrow. Next, a roller - a compactor - compactor enters the work, which provides regrinding of soil lumps on the surface and subcompaction of the treated layer. The last in the process chain is a mulch roller, which ensures the formation of a compacted seed bed for seeds with simultaneous mulching of the compacted soil layer. The use of combined units in the technologies of cultivation of winter barley and wheat allowed to achieve a reduction in the number of technological operations by 1,5-2,5 times, an increase in the productivity of winter wheat by 0,4 t / ha (9%), a reduction in fuel consumption by 40%, operating costs 1,4 times with the economic effect of 1500 rubles / ha and the profitability of production of 140%
The main subject spotted in this article is a calculation method which helps to depict optimal temperature conditions for seeds stimulation by infrared radiation useful for electromagnetic processing and seed-pelleting with perlit next. The analysis helped to depict that the convenient technical aspects of shortwave infrared radiation is in range 0,76-1,4 mcm. This kind of infrared radiation has the greatest penetrating power into the grain to stimulate. According to the methodology a rapid increase of the temperature of seeds after the critical point reaching during IR treatment leads to the properties deterioration of the of thermolabile materials. The temperature gradient during the IR treatment of seeds has the opposite direction of moisture content and depends on the preliminary humidity of the material. This affects the pre-planting cultivation quality of seeds. To avoid overheating and seeds damage there was a mathematical model of the optimal temperature of the IR radiation calculated. As the result of this method there was obtained the calculation of temperature conditions for IR treatment and heating rate depending on seeds humidity. This calculation method helps to define optimal temperature conditions to avoid harmful influence on seeds due to heating. There was data fitting during this method creation and evaluation which defines the effectiveness and perspective of this elaboration
