History of the project
EAWS is originally an extension of the Automotive Assembly Worksheet (AAWS) developed by the IAD (Institut of Ergonomics at the Darmstadt University of Technology) on the basis of the “New Production Worksheet”, initiated in 1997 by General Motors Europe (GME), and the “DesignCheck”, realized at the same time at Porsche.
The development of the EAWS was carried out between 2006 and 2008, by occupational health, biomechanical and industrial engineering international experts from all over the world, coordinated by the IMD (International MTM Directorate).
The field test was run in multinational companies that allowed the team to analyze relevant processes that represented different production contests. In this way all the necessary tests were performed before the last release of the tool (Field Application Group).
In addition, software companies were involved during EAWS development in order to implement and develop specific software solutions based on EAWS structure (Engineering Application Group). The needs to comply with the standards pushed the companies to have at their disposal a 1st level ergonomic analysis system to evaluate the biomechanical load in its components (postures, forces, etc.) for the whole body.
The EAWS meets these requirements.
During its development in particular the following design criteria were taken into account.
The tool had to be accepted and considered exhaustive by:
Applicator deviations – e.g. the gap between the analysis results of different applicators – had to be minimized, rendering the identification and measuring of technical actions, awkward postures and forces at maximum objective.
The tool should have the capability to be used during the planning of the product/process as well as in the production process.
