E.A. Salina, L.Yu. Filimonyuk, L.G. Tsesarskiy, I.I. Sholomov, K.I. Sholomov
The approach to representation of processes of occurrence and prevention of accidents with participation of the human factor is offered. The mathematical apparatus used is based on the theory of cause-effect complexes, Markov processes and probabilistic safety analysis. The developed mathematical support allows to reveal new variants of critical combinations of technical failures and special states of operators leading to occurrence of emergency situations. An example of the use of the developed security in the case of the aviation-transport system is given.
Keywords: aviation transport system; accident; safety; human factor; critical events’ combinations; event tree.
