HUMAN RELIABILITY-ANALYSIS - A HUMAN POINT-OF-VIEW

Present human reliability analysis (HRA) is like a Centaur in that it is only half human. Error psychology is expected to provide a path leading us in the right direction. Al technology can be utilized to better understand errors. It is pointed out that the next generation HRA will require two additional components in which an analysis is made to identify two sets of error prone situations (EPSs): one in which human operators are likely to initiate critical events, and another in which they are likely to override engineered safeguard features. Carefully designed empirical studies are believed to be useful in obtaining general knowledge about critical EPSs. It is suggested that any future effort should be made based on sound psychological concepts.
