CURRENTTRENDS IN HUMAN RELIABILITY ASSESSMENT

摘要

Human Reliability Assessment (HRA) is more than four decades old, and this paper seeks to review current trends in its use in applied settings. It focuses on nuclear power, rail and air traffic industries, with a more cursory look at space exploration, aviation and medical risk. Three trends are discussed: a shift towards data-informed approaches; a preference for so-called 1st Generation approaches, whilst 2nd Generation techniques remain under development; and a debate over the relative utility of quantitative and qualitative approaches in safety cases. The conclusion is that whilst debate continues over HRA's validity and 'simplification' of human error contexts, people in industry still find it helps in the assessment and management of human-related aspects of safety.
