The article analyzes the forecasting techniques of functional safety parameters of technical systems. It was concluded that the feasibility of using GERT-models. The results of the study of technical systems analysis methods based on random stochastic GERT-models. Developed stochastic GERT-models of various types. As a result, the simulation found that the introduction of additional simulation conditions (for example, the account of possible violations of the functional safety) increased the accuracy of the results of evaluation of the temporal characteristics of performance models.
