When selecting technology options for additive manufacturing, it is important to be guided by a list of basic requirements for manufactured parts, powder material features, and the range of equipment specifications. To develop the most effective solution, pilot testing of the technology will be required to determine the preferred process modes that ensure the required quality, cost, and manufacturing time. Accordingly, for such industries, it is important to develop a model that describes the stages of additive manufacturing. In this regard, this paper is devoted to considering the issues of optimization, planning, and management of additive manufacturing technology based on multiple criteria for selecting the most effective technology that involves optimal loading of production facilities. The proposed model introduces indicators that characterize adaptation and allow arguing the practical benefits of using 3D printing technologies. Comparison of process routes by these indicators allows choosing a specific manufacturing route. Having selected the manufacturing option, it is possible to calculate the most efficient placement of products on platforms, as well as to develop a suitable sequence of execution of the main manufacturing operations in order to minimize costs and time expenditures. It was found that the use of the proposed model allows to reduce the manufacturing time of a batch of products by approximately 2.5%. Thus, the proposed model can be useful in additive manufacturing to reduce downtime of installations and speed up the release of products.

A survey of the frame-panel building was carried out, in which ecowool was used as the heat-insulating material. A study was made of the moisture state of wooden frame walls and attic floors. Ecowool samples were taken from various sections of the wall. No mold was detected on material samples. In this case, the sorption humidity was not more than 16%. The results of laboratory tests of ecowool showed high persistence of density and coefficient of thermal conductivity during long-term operation. Tests were conducted to determine the effect of moisture on the change in the physical and technical properties of ecowool. The research results were processed by statistical methods. As a result of the study, it was found that moisture does not accumulate in the ecowool layer of the examined frame walls and attic flooring, but goes out through the insulation and elements of the building envelope. The conducted studies allow us to predict the preservation of the heat-shielding properties of ecowool during operation for a long time

This scientific study presents an analysis of organizational conflicts, as well as problematic aspects of activity in contemporary realities. The effect of organizational conflict on the effectiveness of an individual is shown. The urgency of researching the problem of the activities of the organization’s employees in the context of organizational conflicts, as well as ways to solve them, is given The analysis of the cognitive model. As factors used to reduce tensions in a team, it was proposed to introduce factors for raising qualifications and organizational culture. These factors will influence the target factor - performance. In the course of simulation modeling, it was found that by carrying out activities to improve the skills of employees, measures to increase the level of organizational culture of employees, the organization seeks to reduce tension in the team and, as a result, there is less staff turnover.

The project for creation of the first in Russia Engineering Forum of scientific and technological activities, social and technological entrepreneurship “Rozmysly” is presented, this forum develops the principles of an open public interdisciplinary electronic environment. The substantiation of the social significance of the project is given. The new project implies involving an even wider range of practitioners, research engineers, young scientists, applicants, graduate students, students and even senior pupils in scientific engineering knowledge by providing them with the opportunity to publish, read and discuss the results of promising research and development works, engineering solutions, inventions and rationalization or innovative proposals in the form of an electronic preprint. Conceptually, the project represents a new culture of scientific publications based on global and mini Internet platforms. It is shown that the basic advantage is achieved through the implementation of an open access initiative. From the date of publication, the material is available for the widest possible range of readers. The project is a kind of an interdisciplinary scientific and technological engineering forum.

In this work, the impact of the impact of the loads on the work of the optical system of landing the aircraft on the deck of the ship is studied. The influence of a shock pulse from the landing gear of an airplane during interaction with the deck is considered. Also the deviation of the light beams of the optical landing system and the making of constructive solutions for ensuring the required values ​​of the beam deflection are estimated.

Keywords: impact pulse, optical landing system, automation of optical systems design, reduction of light rays deflection
