The new method for risk assessment of the man-machine system functioning is proposed. The feature of the method is combining the fuzzy fault tree analysis and theory of fuzzy reliability of algorithmic processes. This provides a consideration from a unified framework the structural accidents with algorithms of its detecting and avoiding. Method also allows to use fuzzy “if-then” rules about man...

In modern object oriented computer systems the internal state of the entire system consists of the internal states of many objects probably distributed over a heterogeneous network of computers The man machine interaction in such an application is based on the visualization of states on one hand and the modi cation of states in combination with event generation on the other hand This paper desc...
