Abstract: The subject of the study is the safe and reliable operation of the engineering and technical composition of airfields. The object of the study is the means of collective protection against aircraft noise. The authors consider examine such aspects of the topic as ensuring the proper protective and operational characteristics of collective protection equipment for the purpose of their effective operation by the engineering and technical composition of airfields. Particular attention is paid to such features of the topic as the methodological provision of ergonomic expertise as a tool for comprehensive assessment of the protective and operational characteristics of collective protection equipment. During the research methods of the theory of reliability, collection and processing of expert information, ergonomics, occupational medicine, hygiene, labor physiology, engineering psychology were used. The main conclusion of the study is that the developed methodology provides an objective ergonomic examination of collective protection against aircraft noise and can be used in selecting and testing collective protection equipment, as well as in justifying proposals for their improvement. The novelty of the study is determined by the ability to assess the effectiveness of collective protection facilities by combining objective and subjective assessments of the information characteristics of acoustic efficiency, operational and ergonomic properties.

Abstract: The subject of this research is the ensuring of reliable professional activity of the flight and engineer technical personnel of aircraft under the impact of aircraft noise. The object is the functional reliability of operator of the aviation ergatic system. The author examine such aspect of the topic as the analysis of reliability of professional activity of aircraft flight-lifting and engineer technical personnel that ensures the employment of modern aircraft in execution of their professional responsibilities at workplace, including the use of individual and collective protection from noise. The research methodology combines the methods of reliability theory, acoustics engineering, aeronautical acoustics, system analysis and probability theory. The main conclusions of the study consist in the positions that aircraft noise is a potential source of danger, which substantiates the increased risk of erroneous actions of aviation professionals and development of professional diseases that result in the early professional disqualification. Authors’ special contribution into the research of this topic lies in acquisition of the quantitative estimates regarding the potential unreliability of actions flight-lifting and engineer technical personnel.

Abstract: Abstract. The study focuses on the issues of adequate forecasting of investment in scientific and technical products and expertise of design solutions in order to support management decision-making at the early stages of the life cycle of such products. The implementation of design solutions being considered in the planning of production volumes is associated with non-recurring costs related to the development, production and operation of the products. The main areas of the study are: forecast of the cost of scientific and technical products, determination of the volume of investment in production and estimation of operating costs. The methodological basis of the study involves the methods of economic forecasting, systemic analysis as well as the theory of reliability and the theory of design and testing of complex systems. The main results of the study can be summarized as follows: the development of adapted methods to forecast the cost of scientific and technical products, determine the volume of investment in production and operating costs; the practical use (combined application) of these methods enabling to substantiate the needed amount of investments into scientific and technical products at the stage of design solutions
