THE CONCEPT OF A MODEL FOR MANAGING THE RISK OF FATIGUE IN THE WORKPLACE AND CONTROLLING THIS CONDITION OF EMPLOYEES DURING THE IMPLEMENTATION OF STATE REGULATION AND EXAMINATION OF ENTERPRISE ACTIVITIES

Purpose. To develop a concept for a model for managing the risk of workplace fatigue, taking into account both the intensity of the negative impact of fatigue factors on the employee in the workplace and the intensity of their recovery from such impact to prevent incidents in organizations and industrial accidents and disasters at high-risk facilities. Method. An analysis of scientific literature — to update the purpose and definition of research tasks; methods of the theory of Markov processes — for a formalized description of the random processes of the development of the state of fatigue in the employee and their recovery from the state of fatigue during the work shift. Results. The proposed conceptual models allow the organization to manage the risk of fatigue by adjusting the duration of work and rest periods, depending on the characteristics of the parameters of the intensity of the negative impact of fatigue factors on the employee and the recovery of their body from such an impact. By changing the characteristics of the specified parameters, it is possible to determine the duration of the work periods that maximize the time an employee can work without entering a state of fatigue and the duration of the rest periods that minimize the time required for full recovery. Originality. A conceptual approach for managing the risk of fatigue is proposed, by establishing dependencies between the duration of work and rest periods and the characteristics of the parameters of the intensity of the negative impact of fatigue factors on the worker and their recovery from such an impact, based on the application of the theory of Markov processes. Practical value. The application of the proposed models allows increasing the level of labor productivity in the organization, by determining such durations of work and rest schedules, which provide the opportunity for employees to perform labor activities during the maximum possible time period of the work shift, without reaching a state of fatigue.
