This paper reviews a number of approaches which can be used to identify human errors in human-machine systems. These approaches range from simple error classifications to sophisticated software packages based on models of human performance. However, the prediction of human behaviour in complex environments is far from being an easy task itself, and there is(More)
This is the first in a two-part series of papers dealing with the area of assessing human errors in high risk complex systems. This first paper outlines thirty-eight approaches of error identification, categorising them into types of error identification approach. The paper then reviews these techniques with respect to a broad range of criteria. Viable and(More)
This is the first of a set of three papers reviewing the validity of three Human Reliability Assessment (HRA) techniques used in the UK to predict human performance in high risk industries. The techniques are used to determine the risks inherent in such industries due to human error, and also the benefit in terms of risk reduction by having human operators(More)
This is the second paper in a series of two, reviewing human error identification approaches for risk assessment of high risk socio-technical systems. The previous paper identified and reviewed thirty-eight techniques. One of the closing comments was that no single technique sufficed for all the practitioner's needs, and that a potential way forward was to(More)
This is the second part of a two-part review of human error identification (HEI) approaches in human reliability assessment (HRA). Part 1 reviewed the probabilistic risk assessment (PRA) context in which HRA occurs, and then detailed 12 HEI techniques which have evolved in the field of HRA. Part 2 attempts to compare the way these techniques perform against(More)
The Conservation Reserve Program (CRP), established by the Food Security Act of 1985, offers annual rental payments to farm operators who voluntarily retire environmentally sensitive cropland under tento fifteen-year contracts. The CRP is notable for the size of both its budget and its environmental benefits. The CRP currently pays about $1.7 billion per(More)
This paper is concerned with practical experiences of achieving human factors and safety interventions in the nuclear power and process control industries. It rests upon the premise that, although human factors (HF) and safety may be technological in approach, they nevertheless must operate in a socio-technical environment, within companies with corporate(More)
This paper measures the economic impact of climate change on US agricultural land by estimating the effect of the presumably random year-to-year variation in temperature and precipitation on agricultural profits. Using long-run climate change predictions from the Hadley 2 Model, the preferred estimates indicate that climate change will lead to a $1.1(More)
