Heart Error Analysis

the field of human reliability assessment (HRA), for the purposes of evaluating the probability of a human error occurring throughout the completion of human error heart methodology a specific task. From such analyses measures can then be taken human error analysis techniques to reduce the likelihood of errors occurring within a system and therefore lead to an improvement in human error analysis pdf the overall levels of safety. There exist three primary reasons for conducting an HRA; error identification, error quantification and error reduction. As there exist a number of techniques human error analysis ppt used for such purposes, they can be split into one of two classifications; first generation techniques and second generation techniques. First generation techniques work on the basis of the simple dichotomy of ‘fits/doesn’t fit’ in the matching of the error situation in context with related error identification and quantification and second generation techniques are more

theory based in their assessment and quantification of errors. ‘HRA techniques have been utilised in a range of industries including healthcare, engineering, nuclear, transportation and business sector; each technique has varying uses within different disciplines. HEART method is based upon the principle that every time a task is performed there is a possibility of failure and that the probability of this is affected by one or more Error Producing Conditions (EPCs) – for instance: distraction, tiredness, cramped conditions etc. – to varying degrees. Factors which have a significant effect on performance are of greatest interest. These conditions can then be applied to a “best-case-scenario” estimate of the failure probability under ideal conditions to then obtain a final error chance. This figure assists in communication of error chances with the wider risk analysis or safety case. By forcing consideration of the EPCs potentially affecting a given procedure, HEART also has the indirect effect of providing a range of suggestions as to how the reliability may there

HEART technique for Quantitative Human Error Assessment The Human Error Assessment and Reduction Technique (HEART) human error analysis definition was developed by Williams in 1986. Since that time it has been widely used within the UK and continental Europe for the purposes of assessing human reliability. HEART is an https://en.wikipedia.org/wiki/Human_error_assessment_and_reduction_technique easily-used form of human reliability assessment that has been used by a number of organisations since its development. This technique, which is derived from a wide range of findings in the ergonomics literature, has been designed to be simple and easily understood. It assumes that basic human reliability is dependent upon the generic nature of the task to be performed. and that http://www.synergy-ergs.com/heart.php under 'perfect' conditions this level of reliability will tend to be achieved consistently. HEART also assumes that any predicted reliability of task performance may be expected to change as a function of the extent to which identified Error Producing Conditions (EPC) might apply. HEART identifies nine generic task types and proposes nominal human unreliability values and their suggested bounding values, together with thirty eight Error Producing Conditions. Depending on the amount by which the EPCs are judged to affect the predicted unreliability a selection of error reduction strategies are suggested to combat the most deleterious effects of any identified EPC. Synergy Experience with HEART HEART Applications Synergy has used HEART in a number of nuclear industry PSA studies. In the last two years, Synergy has applied HEART in the following installations to support PSAs: Nuclear submarine refit facilities at Devonport for DML. This included the assessment of both process control operations and the physical tasks necessary when dismantling and re-assembling reactor plant.
