Optimizing the ergonomic design of these work stations is the responsibility of the Austrian REFA engineer and MTM practitioner, Herbert Haider.
He has already been using a combination of the UAS, logistics and ” particularly for logging data ” the MTM office system building blocks for some time in order to shape processes and obtain key productivity figures.
After attending a teaching course on EAWS (Ergonomic Assessment Work Sheet) with the paper and pencil method, he held talks with Dr. Steffen Rast, Specialist Lecturer in Ergonomics at the German MTM Association. He expressed his view that the manual completion of the forms (4 pages) was unsatisfactory and EAWS as a component in MTMergonomics® was not an option for him as it only works if the TiCon® software has been installed.
Dr. Rast had a precise recommendation for this kind of case: “After carrying out tests at suitable pilot work stations, EAWS Digital can be used without the need for any other software.? So they agreed to launch the pilot project with the newly developed EAWS Digital add-on at KNV; it functions both as an isolated program and when integrated in other systems environments. The individual analyses are stored on the hard drive as files and can be opened from there by double-clicking them or they can be shared between PCs.
The range of functions includes:
This is where the outline conditions of the analysis are displayed and edited. They include work and break times, the numbers of items, cycle time and information on the work station (e.g. “restricted freedom of movement?).
– Work process:
This is where all the relevant information on the performance conditions for the individual working stages is listed.
This is where the detailed ergonomic assessment of the stages defined in the work process is found.
The work process, which is structured in the form of a table, forms the heart of EAWS Digital. Each line corresponds to a working stage with a constant ergonomic stress situation, e.g. related to a person?s posture or the weights that have to be coped with. The duration of each working stage is measured, estimated in a qualified manner or determined otherwise and also entered on this line. The input of the data then takes place via additional templates, which can be opened by clicking the mouse. Each analysis results in two points scores, which represent the stress levels for the whole body and the pressure exerted on the upper extremities. As is normal with EAWS, the result is visualized with traffic sign colors ranging from green (no ergonomic problems) to amber (possible risk) or even red (high risk), depending on the number of points. Herbert Haider says there is an additional benefit: “As a safety engineer, it?s also very important for me that as many relevant issues are processed for the risk assessment, which has to be prepared anyway.?
