Abstract. The article provides an overview of the applicability of statistical methods for assessing the results of production processes in various industries. The authors emphasize the effectiveness of the system approach implemented in the methods of analysis of variance, which contributes to technology improvement and allows the influence of each factor and their interaction to be studied in detail. In addition, the results of the analysis of variance can be integrated into the quality management system, which makes it possible to continuously monitor and adjust production processes, and prevent deviations in the output parameters of various parts. The paper provides an example of applying the analysis of variance in the study of technological processes of pressing the components from various materials in designing, manufacturing and controlling the quality of defense and industrial products.

Keywords: analysis of variance, statistical methods, experiment, technological process.

Abstract. The article proposes a method for automated high-precision assessment of the danger of approaching aircraft in case of violation of established separation standards on a continuous 100-point scale. The technique is a step-by-step search for the maximum hazard of approaching aircraft from the moment of the beginning of the violation of separation intervals to the end of the conflict situation. The main criterion for assessment is the linear functional dependence of the values of the minimum distances between aircraft, weighted in the established separation standards. A 100-point assessment will allow for the comparison and comparison of potential hazard between different facts of violations of separation standards, the severity of the threats and risks to flight safety contained therein.

Using “perceived hazard” as a reference points allows assessing the level of flight safety even in the absence of violations of separation intervals for the selected reporting period. The analysis of the estimates obtained using the methodology will help to take timely preventive measures to eliminate potential threats even before the occurrence of real aviation events.

It is advisable to use this methodology in solving the tasks of automating the assessment of practical skills of air traffic control personnel and creating an automatic flight safety management system.

Keywords: normalized coordinate system, normalized distance, violation of separation intervals, hazard of convergence, methodology for assessing the hazard of convergence.

Abstract. The article discusses various methods of risk assessment in the field of of process safety at an airline. The purpose of the study is to determine the most appropriate risk assessment method to increase the level of safety at work and reduce the probability of dangerous situations. When analyzing the methods for detecting and identifying hazardous events and negative situations, we have highlighted the most effective ones. Based on this, the authors have created diagrams such as the “tree of incidents” and the “tree of events” has been developed for the event: industrial injury. The article considers the matrix method as one of the most common methods in the practice of professional risk assessment.

Key words: airline, risk, occupational risk, labour precaution, accident tree, event tree, noise, dangerous occupational factor, harmful factors.

Abstract. The need for this study arose against the background of the analysis of numerous publications, standards and identification of contradictions affecting vital problems of assessing the efficiency and effectiveness of the quality of work and services in the air transport industry. The analysis of theoretical and practical approaches in the studied area was carried out for solving the main task which is the development of correct terminology and practical introduction of the conceptual apparatus into new methodological approaches to creation and implementation of an integrated safety management system for an aviation service provider.

Keywords: product quality, aviation service provider, safety, integrated system.

Annotation. The article provides statistical data on passenger turnover of air transport in comparison with other types of transport in Russia, as well as flight safety indicators over the last decade. The leading types of events leading to aviation accidents have been identified. It has been revealed that the cause of many of the negative aviation events that have occurred are violations of the functional state, loss of performance and errors of crew members, which are facilitated by the conditions of the person’s environment.

The authors study the variability of heart rhythms, reflecting changes in the psycho-emotional state of a person during noise. The results of the study confirm that a change in the activity of the sympathetic and parasympathetic parts of the autonomic nervous system of the human operator. This indicates the development of stress under the influence of noise.

The authors demonstrate the importance of counteracting the negative effects of noise on aviation personnel to improve flight safety and reduce injuries and propose to use otoprotection with an oxygen-argon gas mixture to concentrate the attention of the crew in extreme situations.

Key words: air transport, aviation accidents, human factor, noise, otoprotection, argon.

Abstract. The article examines the fatigue of flight personnel and members of the air traffic control service as a risk factor affecting flight safety. The proposed software solution based on the random forest method makes it possible to identify the state of fatigue in an aviation specialist after passing a series of tests evaluating a decrease in performance based on existing symptomatic attributes. The introduction of the presented solution into flight safety management systems at aviation enterprises will improve the corresponding reliability indicators of both pilots and air traffic controllers.

Key words: fatigue, assessment, statistics, machine learning, binary classification, random forest, automation, program.

Abstract. This work is a continuation of two stages of scientific research, where a universal algorithm for a system of applying statistical methods to manage non-conforming products has been developed and outlined.

The results obtained and their analysis made it possible to expand the range of studies and develop recommendations for improving the efficiency of the planning and forecasting of the technical and economic indicators of the enterprise, depending on a priori information on the influence of external and internal factors.

Keywords: a priori information, statistical methods, non-conforming products.
