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 study is the safety of vital activity of the flight and engineering-technical personnel of state aviation. The object of this study is the acoustic safety of professional activities of the flight and engineering-technical personnel of state aviation. The authors meticulously examine such aspects of the topic, as the assessment of working conditions of the flight and engineering-technical personnel of state aviation considering the noise and infrasound; risks of reducing the overall and professional performance due to the impact of the acoustic factor; as well as reliability of the flight and engineering- technical personnel of state aviation. Methodology of the research combines the methods of engineering acoustics, reliability theory, aviation medicine, occupational medicine, ergonomics, and probability theory. The main conclusion consists in substantiation of the need for developing and implementing the special means and methods to ensure the acoustic safety of professional activity of the flight and engineering-technical staff of state aviation as an integral part of the system for providing the safe aircraft operation. It is demonstrated that the system for preventing the negative impact of noise upon the aviation personnel must be comprehensive, as well as include technical and organizational measures, monitoring of the working conditions of flight and engineering-technical personnel, availability and proper application of the individual and collective noise protection, dynamic medical supervision over the flight and engineering-technical personnel of state aviation, with the implementation of a complex of medical-preventive and health-improving measures.

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
