Theoretical Study of Improving the Safety of the “Operator, Machine, and Environment” System when Performing Transport Operations

The article considers the issues of a systemic approach to studying safety levels in transport operations and ways to increase the safety of the operator-machine system in Russian transport. The principal and problematic issues of reducing the risk of injury by preventing traffic accidents and reducing the severity of their impact have not been sufficiently addressed. When performing transport operations, there are often disagreements between the elements of the “Operator, Machine, and Environment” technological system due to the influence of external conditions and parameters of the constantly-changing environment in the workplace. This leads to a sharp increase in the number of failures of system elements, which reduces the level of safety of transport operations. Analysis of the impact of major factors on the risk level when the operator performs transport operations has shown that it is necessary to study the nature of the change in the input and internal factors that influence the risk level of the “operator” subsystem. The “operator-machine” system operates in conditions, which are constantly changing and are random in their nature. Quantitative evaluation of the “operator” subsystem is determined by the qualifications based on the correctness of actions and their speed. To increase the level of the system’s output factors it is necessary to improve the functional ability of the “operator” subsystem.
