The probability of human error and failure rates in technical ATO systems

F. Adebahr and H. Schäbe compare the results of an investigation into human reliability, as determined using classical methods (Hinzen + RARA), with results that have been generated with the help of methods used to derive a safety integrity level for technical systems. A special feature of the comparison involves the fact that the probability for human error is represented per request, while a tolerable functional failure rate must be determined for technical systems. Both quantities must be made at least comparable using suitable methods.
