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 therefore be improved (from an ergonomic standpoint) and hence minimising risk.

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. Human Error Analysis Examples 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 therefore be improved (from an ergonomic standpoint) and hence minimising risk. Factors which have a significant effect on performance are of greatest interest. Based around this calculated point, a 5th – 95th percentile confidence range is established. 3.

(1985) HEART – A proposed method for achieving high reliability in process operation by means of human factors engineering technology in Proceedings of a Symposium on the Achievement of Reliability in Operating Plant, Safety and Reliability Society (SaRS). What Is Human Error Analysis There exist three primary reasons for conducting an HRA; error identification, error quantification and error reduction.

Other factors to be included in the calculation are provided in the table below: Factor Total HEART Effect Assessed Proportion of Effect Assessed Effect Inexperience x3 0.4 (3.0-1) x 0.4 + 1 =1.8 Opposite technique x6 1.0 (6.0-1) x 1.0 + 1 =6.0 Risk Misperception x4 0.8 (4.0-1) x 0.8 + 1 =3.4 Conflict of Objectives x2.5 0.8 (2.5-1) x 0.8 + 1 =2.2 Low Morale x1.2 0.6 (1.2-1) x 0.6 + 1 =1.12 Result[edit] The final calculation for the normal likelihood of failure can therefore be formulated as: 0.003 x 1.8 x 6.0 x 3.4 x 2.2 x 1.12 = 0.27 Advantages[edit] HEART is very quick and straightforward to use and also has a small demand for resource usage [3] The technique provides the user with useful suggestions as to how to reduce the occurrence of errors[4] It provides ready linkage between Ergonomics and Process Design, with reliability improvement measures being a direct conclusion which can be drawn from the assessment procedure.

The first stage of the process is to identify the full range of sub-tasks that a system operator would be required to complete within a given task. 2. Only those EPC’s which show much evidence with regards to their affect in the contextual situation should be used by the assessor.[2] Worked example[edit] Context[edit] A reliability engineer has the task of assessing the probability of a plant operator failing to carry out the task of isolating a plant bypass route as required by procedure.
