Abstract

The possibility of imitation modeling of automatic recovery of a computer fault-tolerance system, whose elements have additional hardware and software redundancy in case successive failures, is considered on the base of a directed probabilistic graph whose tops correspond to possible states of the system, and the arcs between them determine the probabilities of transitions from one state to another, the arc length determines the random time of automatic recover, statistical characteristics of the recovery process are determined on the base of passage of the routes along the probabilistic graph from initial top to the final one.
