Abstract: The method and the apparatus are concerned exclusively with dynamic processes that can be represented dominantly by discrete-event processes and for the dynamics of which it is not the time but rather the logical order of the symbols that is critical. The method and the apparatus cater to the specifics of discrete-event problems. The technical apparatus for designing and realizing automated reactions to the failure of actuators and sensors in discrete automation-engineering installations ensures that the effects of said failures on the process remain at a minimum, and also a method that allows said faults to be systematically integrated into discrete-event models in order to take this as a basis for carrying out formal design of fault-tolerant discrete-event controllers.
