It is shown that expansion of functional capabilities of forest machines is the most important factor in increasing efficiency of the complex of works on the forest. Based on functional and technological analysis new technical solutions are proposed.

The article discusses the issues of effective cost management at the enterprise. Attention is paid to organizational issues of introducing management accounting system at the enterprise. The features of cost management at a catering enterprise are clarified, the stages of the accounting process are highlighted in the cost centers of the organization.

The part of the training of highly qualified specialists in the field of automation is the use of training and laboratory stands in the educational process of bachelors of the specialty 5B070200 "Automation and Control". At the department "Automation of production processes" (APP) of KSTU widely used laboratory complexes based on the equipment of world companies. The goals and objectives of the development of a new teaching and laboratory stand are determined. Studies of the selected programmable logic controller (PLC) are performed. PLC-compatible hardware and programming environment for the PLC is searched. The laboratory stand “Mechanical processing area” is selected as the control object. A flowchart of the control object and its control system have been developed. The main goal is the creation of a laboratory and methodological complex for studying the stand “Control system based on a Mitsubishi FХ5U controller” to control a real object — a belt conveyor made by Fischer Technik.

The article deals with the system of organization and protection of aircraft and air terminal complexes in the Russian Federation.

The process of drilling wells using the automatic control system of the digital electric drive of the drilling winch (Simoreg 6RA7088), which belongs to the main drives of the drilling rig is considered in this paper. The productivity and efficiency of the drive of the drilling winch depends on the productivity and efficiency of the drilling rig as a whole. The author convincingly reveals and proves the advantages of using the electric drive Simoreg 6RA7088–6KS22: increase in durability and re-liability; reduction of commissioning and repair work; the decrease in the number of staff; increased productivity and economic efficiency from the installation of a DC motor with controlled by microprocessor Converter Simoreg 6RA7088–6KS22, compared with the DC motor controlled by thyristor voltage Converter of the type KTU-K14-UHL1.

The properties of a composition based on modified polyethylenes have been studied in the work. Polyolefin thermoplastic elastomers were obtained on the basis of ethylene-propylene elastomers and high-density polyethylene by the two methods: in the first case, as a modifying agent sulfur-containing compounds (altax, sulfur) were used, and in the second – MAC. Thermoplastic elastomers of the series A were obtained as a result of a combination of the original polymer components melt on the mill rolls at a temperature of 433–453 K° at the gap between them 0.2 mm. After crystalline thermoplastic melting ethylene copolymer problemby EPS and structuring agents were added. To achieve a good homogenization milling was carried out for 25 minutes. Formulation of the compositions had the following composition (pts. wt): EPDM – 100; HDPE – 10–80; dicumyl peroxide 1–2.

Controlled knowledge and skills are the subject of consideration. In order to find a universal method of evaluation, elements of formative assessment, assessment using a skill test, and an open type task as a component of the student's overall learning system were analyzed on the basis of Russian language lessons. As a result, several tasks were formulated for formative evaluation, test, open-type tasks and criteria were developed. Such system of work can be used in school in Russian language lessons.

Economic growth in the context of global intercountry competition is provided on the basis of the state policy of supporting national development. The effectiveness of such a policy is determined by the ability of the state to ensure transparency and completeness of control over the movement of resources, including the potential for outflow of resources to countries with more attractive business conditions, in particular, through transfer pricing.

An example of the course of extracurricular activities on the basics of programming the Arduino microcontroller. Describes the features of using project method in teaching electrical engineering for students.

The article describes the main parameters that determine both the traction ability of the transmission and the life of the belt, which is the magnitude of the belt tension and its correspondence to the actual transfer load. The appendix shows the characteristics of the belts and their elasticity: shortening the belt when stitching or cross stitching for pulling; periodic movement.

The article recommends a new scheme of the belt drive with PPO, provides the Law of the vibrational motion driven branch of a belt in contact with an elastic sleeve of the tensioner and shows graphical variation of the vibration amplitude of movement and the speed of belt driven branch in the function of values ​​of the eccentricity and roll stiffness of the elastic sleeve.

The researchers of this article describe the methods of external environment control and the prospects of its implementation in the company. It was concluded that the environment control services use both general scientific and specific research methods.

It showed that in the years 1984-1985 as one of the directions of mechanization clearcuts considered the creation of the machine, providing a roll, take away from the cutting area and stacking trees tickets manipulator of 15 m and drive.

The problem of formation of the system of controlling production is due to the need to find a compromise between the integrity of its presentation and detailed description of its elements. This issue is resolved by the author through the development of a conceptual model of the SEC.

The author discusses the aspects of marketing development in the country, its evolution and transformation. Marketing as a science appeared in the Russian Federation after the transition state structure from a centralized to a market system. The very novelty of the subject, and especially a large flow of information, marketing in education very often leads even the experts are stumped, not to mention those who only starts to study this discipline. The challenge now facing us is to convey more detailed information and at the same time in reasonable form.

This article illuminates one of the most promising methods for signal synthesis and also describes the basic elements used to create a signal generator and the possibility of manufacturing the device.

В работе приведены схемы разработанных систем для локального и удалённого мониторинга и контроля температуры и влажности, проанализированы преимущества перед существующими системами.
