Risk assessments are not a one-off action, but there are no formal guidelines on when and how often a risk assessment should be carried out. Changing factors affect the risk assessment parameters. The strongest influence of these changes is the probabil ity of an accident. The article describes the main parameters of a model that is built on the basis of an asset and the incident scenarios defined for it. An analysis of the changes in the probability of an accident has been made. Dependencies are derived to determine the appropr iate periods for checking the risk factors. These periods must ensure an acceptable level of risk, which is within acceptable levels for the organization.

The present trend in the development of highly efficient technological equipment for the production of nanomaterials is being analysed. It is associated with the synthesis of energy-efficient control methods for the operating modes of electromechanical disintegrator of multifactorial action. As a result of genetic modelling, the deterministic relationship between the genetic information of generative electromechanical chromosomes, structure of the resulting magnetic flux in the active zone of electromechanical disintegrator and its functional operating modes has been established. According to the results of structural synthesis, methods for technical implementation of energy-efficient modes of material processing, which ensure the increase of productivity of the electromechanical disintegrator, have been optimized and developed. The credibility of theoretical results was confirmed by experimental studies.
