Applicability of human reliability assessment methods to human---computer interfaces

摘要: The UK Office of Nuclear Regulation (ONR) has undertaken a Generic Design Assessment two nuclear power station designs for prospective construction in the UK. This assessment included review Human Reliability Assessments (HRAs) submitted as part probabilistic safety assessments (PSAs). Both reactor have human---system interfaces driven by digital technology. However, data and methods assessing human error probability (HEP) pre-date such Therefore, ONR sought to establish whether existing HRA remain applicable modern human---interface interactions hence continue provide credible insight into risk contribution from error. An extensive literature was identify or derive relevant HEPs. Data ranged those associated with particular interface objects, plant start-ups post-fault diagnoses. There appear be some interesting paradoxes within explored this paper. Based upon reviewed, it is concluded that reliability are likely optimistic their estimates HEPs where diagnosis involved process control dependent on human---computer interaction. Shortfalls availability published scope been identified work.
