MODELING AND DIAGNOSIS OF TRAINING PRODUCTIVITY OF SCIENTIFICPEDAGOGICAL PERSONNEL
Description
The article presents the criteria for the effectiveness of the scientific and pedagogical workers of higher skill levels for the preparation of scientific and pedagogical staff. It is known that the preparation of the teaching staff (PhDs) - one of the most important activities of higher education institutions; Moreover, when the state accreditation of higher education institutions compulsorily taken into account indicators that reflect the impact of training candidates. Also, of course, that the training of the teaching staff (PhDs) - activities that require both high levels of research and pedagogical competence. This means that the results of scientific and teaching staff higher qualification levels for the preparation of the scientific staff - both indicators of research and pedagogical competence; own training of researchers - an area of "crossing" of scientific and pedagogical activity. Unfortunately, the increase in the number of scientific personnel being prepared does not always mean quality growth. Often trained scientific personnel (PhD) not only do not approach the level of competence of its research (the results of research) to the supervisor, and stopped to engage in scientific activities after defending his doctoral dissertation (or engaged at a low level). Therefore, the article authors consider it expedient to propose indicators that reflect not only the amount and timeliness of the research training (PhD thesis defense sometimes occur many years after graduate school), but also the productivity of this activity. From the point of view of the authors, the success of research training only can be considered productive when prepared by the scientific supervisor candidates of sciences are highly qualified scientific personnel, ie conduct high-level research, the results of which are recognized by the scientific community; the same is true of the scientific advice (highly qualified scientific workers - doctors). The practical significance of the study results - in the possibility of objective monitoring of research activity of scientific-pedagogical personnel of higher qualification. Methodological bases of research: a systematic, competence, sociological, and metasystem qualimetric approaches. Methods: modeling, methods of quality control, methods of set theory, relations and graphs. Normative base of research: the Federal Law "On Education" (2012), the federal state educational standards of higher education (2014, 2015). The work was performed as part of research projects "Monitoring of the research activities of educational institutions in the information society" (№ 16-03-00382) and "Modern information and educational environment" (16-36-00048) with the financial support of the Russian Humanitarian Foundation from 17.03. 2016.

MODERN MODELS AND METHODS OF DIAGNOSIS OF METHODOLOGY COMPETENT TEACHERS
Description
The purpose of the research is development of models and methods of diagnostics of methodical competence of a teacher. According to modern views, methodical thinking is the key competence of teachers. Modern experts consider the methodical competence of a teacher as a personal and professional quality, which is a fundamentally important factor in the success of the professional activity of teachers, as well as a subsystem of its professional competence. This is due to the fact that in today's world, a high level of knowledge of teachers of academic subjects and their possessing of learnt basics of teaching methods can not fully describe the level of professional competence of the teacher. The authors have characterized the functional components of methodical competence of the teacher, its relationship with other personalprofessional qualities (first - to the psychological and educational, research and informational competence), as well as its levels of formation. Forming a model of methodical competence of the teacher, the authors proceeded from the fact that a contemporary teacher high demands: it must be ready to conduct independent research, design-learning technologies, forecasting results of training and education of students. As a leading component of the methodical competence of the teacher is his personal experience in methodological activities and requirements of methodical competence determined goals and objectives of methodical activity, the process of the present study, the formation of patterns of methodical competence of the teacher preceded the refinement of existing models methodical activity of scientific and pedagogical staff of higher education institutions and secondary vocational education institutions. The proposed model of methodical competence of the teacher - the scientific basis of a system of monitoring of his personal and professional development, and evaluation criteria and levels of her diagnosis - targets system of vocational training and re-training of high school teachers. Innovation policy is a model of methodical competence of the teacher, and the main model of the mechanism of its formation - methodical activity (in close connection with other activities). Research methods: analysis of scientific and methodical literature and best practice methodological activities in educational institutions, modeling, methods of the theory of sets and relations, methods of quality control, methods of multivariate analysis systems. Methodological bases of research: a systematic, qualimetric, competence and process approaches. The work was performed as part of research projects "Monitoring of the research activities of educational institutions in the information society" (№ 16-03-00382) and "Modern information and educational environment" (16-36-00048) with the financial support of the Russian Humanitarian Foundation from 17.03. 2016

Description
The work is scientific and practical in nature, same as the discussed process of optimization of power losses in power networks based on the use of the transportation problem, namely the rules of the minimum element of the transport matrix, which is a valid solution. The mechanism of the improvement of the obtained feasible solutions to the tasks focuses on using the potential method, assigning each row and column of the matrix their corresponding potential. Using a basic variable and manipulating the elements of the transport matrix according to a specific algorithm, we implement the construction of a new support plan. Based on the plan and its acyclic, we build two cycles and determine the values of the estimates between direct and indirect transportation costs per unit of output. The resulting algorithm makes it easy to program all computational operations and quickly obtain the result of the optimization of power losses in the design of the electricity network, thereby reducing the economic and technological costs. As a result of joint use of transportation problems and potential method, we could find the optimal solution based on improved solutions more efficiently, and a scheme of optimal electric network. As consumers, in practice, there may be urban and agricultural, industrial enterprises, regional and district subordination, including industrial, agricultural and individual customers

NONPARAMETRIC ADAPTIVE DUAL CIRCUIT CONTROL OF DYNAMIC PROCESSES UNDER PARTIAL UNCERTAINTY
Description
The article considers the tasks of nonparametric dual control of dynamic objects with discrete-continuous nature of the process is considered. In this case, the only value of memory depth of dynamic processes is known, but the parametric structure of the model is partially unknown. The nonparametric algorithms of adaptive dual control for external control loop were offered. The proposed loop of control is designed for systems, which include in technological scheme internal control loop, specifically a standard controller. In solving this problem, the methods of nonparametric identification theory, control theory, the theory of adaptive systems, mathematical statistics and statistical modeling are used. The theoretical information of the non-parametric algorithms of dual adaptive control under conditions of incomplete information of the process is produced. The essential difference between the dual control algorithms from the standard is that the nonparametric control unit performs two functions: research and control of the process of active accumulation of information. The computational experiments show that the introduction of the proposed scheme significantly improves the quality of control, and the existing control system in operating controls are maintained

MATH DESCRIPTION OF THE PROCESS OF THE AUTOMOBILE DIAGNOSING PARAMETER CHANGE
Description
The article shows the importance of math description and grounding the function taking into account the process of changing the parameter when developing the methodology of automobile diagnosing. It is pointed out that after all the prediction error and effort depend on the choice of approximating function. The wrong choice of the function can bring to naught all the efforts to manage safety margin and other parameters of cars elements. One can find the requirements to math description and grounding the function of the parameter change. Based on the analysis of factors influencing the process of parameters change and requirements to math description of this process we have noticed that it is necessary to approximate the change (increase) of the state variable by the chance ordered function with increasing realizations. One can consider the parameter change realization both strictly and not as a monotone function ranging from zero to the limit change of the parameter. We have mentioned that the fore-quoted reasoning with the account of two groups of factors make possible to investigate the parameter change at this or that moment of work as a sum of two random values. We have made a conclusion that they usually express the link between the change rate (for instance, detail wear rate) and the readings of the material properties and functioning conditions (metal skin hardness, unit loading on the detail surface, its relative rate of movement) by the functional determined dependence got as a result of lab tests or theoretical study. In the conclusion, one can see that the analysis of the results of math description of the process of the parameter change is sufficient enough

Description
The article considers the stages of the passage of the project in the organization. Decision support system facilitates the work of heads of enterprises and enhance its effectiveness. The organization has a system of registration applications, which contains the information about the project, its description, the terms of development, the developer (or development team) and stages of this project. Using the software package, the customer leaves the application to provide services. Head sends a request to the appropriate division. Departments, in turn, transmit information about the status of implementation of the application through a software package. The software package enables fast two-way remote communication in electronic form between the customer and the head, and between the director and divisions. The organization coordinating the work on the implementation of IT-projects by the head and the head of the sector. But there are some human factors, through which people can not keep up with the timely implementation of all tasks given by subordinates. Developed DSS helps to save time in monitoring the project development phase, will eliminate the human factor in monitoring the success of the project, and will assist in the decision-making in cases of force majeure. Development of an IT project consists of several stages, each of which has the ability to give interest characteristic of the total time spent on the project. Supervisor carries out the decomposition of the problem and evaluation of each stage

Description
The article contains a scientifically based approach to assessing and improving the reliability of DMU "Frigate" in the conditions of the Rostov region. The studied parameters for the elements with the lowest resource were: mean time between failure, mean time to repair, probability of failure, the parameter flow of failures, failure rate, actual and allowable factors of readiness. The analysis of the main faults of DMU "Frigate", identified nodes and elements, characterized by the low reliability, for which the dependences of probabilities of failure-free operation, as well as the dependence and developed the procedure for calculating the optimal duration of recovery of failed elements, to ensure acceptable availability. Statistics on major faults refuse items were collected over the three irrigation seasons from 2013 to 2015, were investigated failures due to wear of the elements for 17 irrigation machines. As a result of the research we developed mathematical apparatus of calculation and the comparative assessment of the readiness of the parks sprinklers of various farms to perform their processing functions at the same and different number of machines. We obtained the dependence for determining the allowable duration of the recovery elements that will allow you to determine the main directions of improving the reliability of DMU "Frigate" during the operational phase

SOUND EFFECTS INFLUENCE ON THE OPERATOR’S ORGANISM IN PRODUCTION CONDITIONS
Description
Here we present a brief survey of noise effects on human’s organism in production conditions, including noise effects on operators of machines and technical devices. It is well known, that any biological organism exists in balance with its environment. However, noise effects being stress factors knock the operator of machines and technical devices out of the working rhythm and cause different kinds of health disorders such as blood pressure increase, fatigue, disorders of the central nervous system and gastrointestinal tract and the like. All this may lead to accident situations, reduction of labor productivity and quality of work. Frequently health disorders start with hearing impairment which leads to disorientation in the threedimension space and malfunction. It is because the hearing apparatus as biological system provides the organism with sensory information and ensures selfpreservation. In the noise conditions, these characteristics are conflict: on one hand, the hearing organ should possess high enabling capability to receive positive signals, and on the other hand, in order to adapt to the sound hearing and sensitivity will decrease. The duration of noise exposure and the number of years spent under influence of the noise are also of great importance. Thus, it is obvious that control of the noise and prevention of harmful effects of the noise on machine operators are important components of production process in the agrarian sector

METHODOLOGY OF ACOUSTIC SAFETY MEASURING IN OPERATORS’ BOOTHS OF AGRICULTURAL MACHINES
Description
In this article, we have examined the methodology of acoustic measuring with the purpose to create safety conditions for the activity of agricultural machines operators, in foremost harvesters and tractors. We should underline that such studies are based on the state standards that are aimed at improving the level of comfort of the activity of the operators of tractors and harvesters and maintaining their working capacities. Therefore, there is a need for a thorough analysis of the current regulatory legislation (standards that are applied) in combination with analysis of mathematical support of measuring devices (sound level meter). Besides, there is a need for creating strict sequence of actions of the sound level meter operator (algorithm) in combination with the method of conveying information that is adapted to the experiment. At the enterprises, organizations and establishments control of the noise level at working places is checked no less than once a year. The State Standard 12.4.095-80 provides the basis for measuring, position of the control point in the booth, the frame and characteristics of measuring, mode of activity of engines and parts of harvesters, the amount of measurement samples (3 precise measurements), estimation of measurements and their correction, equipment, methods of measuring the results, temporary characteristics of measuring by the sound level meter in “slow” mode and frequency correction
