As part of the project to create a comprehensive resource-saving technology for the associated production of nanostructure concentrates, the reliability of the software package “Automated control system for the technological process of obtaining MD1 and MD2 nanostructure concentrates” was evaluated in terms of providing thermal vortex enrichment. The calculation of the reliability of the system was performed to assess the level of reliability and quantitatively determine the reliability indicators for the implementation of the functions of ACS TO 2.12. The object to be calculated was identified, the goals and objectives of the calculation at this stage, the nomenclature and the required values of the calculated reliability indicators were determined, the calculation method was selected that is adequate to the features of the object, the goals of the calculation, the availability of the necessary information about the object and the source data for the calculation. The initial data for the calculation were obtained and pre-processed; the values of the reliability indicators of the object were calculated. From a comparison of the calculation results with the reference values of the integral safety level (SIL) in accordance with IEC 61508, it follows that the maximum safety level of the ACS TO 2.12 SIL 2, the system availability is 98.97%, and the system uptime is 2 years. The probability of a dangerous failure of the PAZ system is 1.31·10 −4 , which corresponds to a high value of the integral safety level (SIL 4).
