Abstract
The enhanced Bayesian THERP (Technique for Human
Reliability Analysis) method is based on the use of the
time-reliability curve introduced in the Swain's human
reliability analysis (HRA) handbook and on adjustment of
the time-dependent human error probabilities with five
performance shaping factors (PSFs): (1) support from
procedures, (2) support from training, (3) feedback from
process, (4) need for co-ordination and communication,
(5) mental load, decision burden. In the enhanced
Bayesian THERP, the PSFs are elicited by expert
judgments, which are then aggregated in a Bayesian
manner. This approach has been successfully used in real
PSA-studies, where the plant operators have been the
experts assessing the levels of the PSFs. The method has
proven to be a systematic way to qualitatively and
quantitatively analyze operator actions. This paper
presents the application of the enhanced Bayesian THERP
in an international study "HRA Methods Empirical Study
Using Simulator Data."
