Abstract

The method of accident risk assessment at power engineering objects that include significant uncertainty of the input data is presented in this paper. Expert linguistic evaluation of the parameters of the power-engineering object using fuzzy sets is offered in the given task. It is suggested to use the method of risk-events when analyzing the risk of power engineering objects. This method allows to get characteristics of the event risk together with the probability of event occurrence at each stage of accident development. The risk-event method is based on calculations of the generalized tree of risk-events.
