The reliability of machine-building industry technological systems of is determined by the risks of hazardous events: failures of technological equipment, production items, executors of specified technological processes. The paper proposes the use of the G. Heinrich pyramid, built on the basis of the risks of technological system failures, which include primary failure, secondary failure, initiated failures, multiple failure, necessary to determine the significance of the influence of failure risks on the possibility of dangerous events. This is necessary for the organization of safe working conditions for workers through risk management of hazardous events based on a three-planimetric model for managing the reliability of technological systems. The authors have developed a three-planimetric model for managing the reliability of technological systems. The incident management process takes place on the first contour. According to the analysis of the statistics of incidents, the failure factors are managed on the second contour of the model. The third contour is process functionality management. The contours use the “Analytics” database, updating it and the database of possible options for technical solutions with the subsequent adjustment of operating conditions or methods for managing failure risks. Based on the obtained statistical information databases, solutions are being developed to manage the indicated risks of dangerous failures of technological systems. The control contour is closed in the cycle of technological system functioning and its risk management. Automation of the management process can be achieved through the use of resources of a machine-building organization and the development of an information management system for a unified technical condition monitoring system (UTCMS) based on the use of the three-planimetric control system.
