Analysis and risk assessment of risk technical systems in the development of the methodology for the students training by transforming structures

The purpose of this article is to develop a methodology for risk analysis by transforming structures. A methodology for risk analysis is proposed by transforming structures based on existing links between the system description through a block diagram, a fault tree, and an event tree. Risk analysis of risk techniques by fault tree and event tree provides an unambiguous relationship between element parameters and parity of equivalent elements describing a system or a subsystem. An example of risk analysis by transforming structures is presented, according to the proposed methodology applicable to risk identification, including transformations between block diagram and fault tree and event tree, as well as variants to determine their risk (at accepted value of damages), according to acceptances made. A methodology has been developed and examples of risk analysis by transformation of structures are shown.
