Predictive models of human performance and guidance on Human Assurance Levels

This task will develop predictive models of human performance in support of risk modelling and safety assessment The models will include Human Reliability Assessment HRA techniques as used in barrierbased risk models predicting what can go wrong and how likely it will be to go wrong depending on human performance influencing factors In addition human performance models will be developed which give a broader account of human performance variability in safetyrelevant conditions such as timing characteristics for recognition and acting in critical situations information transfer in sociotechnical systems and human workload
