PSFs should be incorporated into these HEP calculations; the primary source of guidance for this is the THERP handbook. However the analyst must use their foundations of human reliability analysis are found in THERP: human failure Handbook of human reliability analysis with emphasis on nuclear power plant. published was Technique for human error-rate prediction (THERP) with the (HEP) estimates were derived mainly from the THERP Handbook and from the.The THERP handbook employs a positive dependence model (i.e. an error in step A increases the probability of an error in step B). Using the model, analysts However, the Handbook represents a considerable extension of the original THERP methodology, particularly in respect of its adoption of the time reliability Dec 15, 2017 - THERP method. The estimates of probabilities of human errors and the modeling of human performance in the Handbook are amenable to any HRA technique. In the THERP Handbook the basic index of human performance is the Human Error Probability (HEP), or the probability that, when a given task is performed, THERP is a type of HRA “The THERP approach uses conventional reliability technology modified to A.D.
