AET—a new job-analysis method

Abstract

The stress-relevant scaling of vocational activities by AET ascertains and compares job demands which are characterized by many different human activities. The AET results thus form a data bank which is suitable for various aims of ergonomic work evaluation and work design. The application of the specific supplement of H-AET in addition to AET itself allows detailed strain classification, especially in the field of demands of activity. If, by a stress-oriented taxonomy for work carried out in the range of vertical reach of the arms, anatomic-geometrical differentiations of vertical reach and biomechanical postural forces are coupled to the workplaces, it is possible to differentiate the scaled activities in a strain-relevant bottle-neck analysis. The characteristics of the scaled items allow the immediate determination of biomechanical risks of damage or the derivation of measures for workplace design.
