Es besteht die Möglichkeit, die Spalten Anzahl und Häufigkeit (A x H) über das Menüband EAWS®-Struktur ein- bzw. auszublenden.
Please note: |
The number of real actions must not be entered in the "Quantity" column! |
The columns Quantity and Frequency (as well as the associated Total Duration column) are hidden by default, since only the time and ergonomic boundary conditions are needed for the evaluation. Both columns behave differently, and this may easily confuse inexperienced users.
If the workflow, however, shall be evaluated typically according to MTM in the sense of process steps (elements), column Q x F can be used for this purpose.
Laut UAS®-Lehrunterlage gilt folgende Definition:
Number |
How many? |
z. B. Muttern, die eingeschraubt werden, Nägel, die eingeschlagen werden, Anzahl Meter je ein Weg |
Frequency |
How often? |
z. B. Umdrehungen/Zyklen je Mutter, Schläge je Nagel, Häufigkeit des gleichen Weges |
Gemäß UAS®-Regelwert muss die Analyse nicht ablaufrichtig sein.
An analysis such as the following can therefore be interpreted in different ways.
Code |
Q x F |
|---|---|
KA |
15 * 2 |
AA1 |
1 * 1.0 |
a)Walk 30 meters and place part >> Load type: Carrying
b)Walk 15 meters, place part and walk back 15 meters >> Load type: Repositioning
A similar problem also arises when using the factors, since it is not clear whether these are distances (KA) or quantities.
Example:
a)15 x 1 KA as load type Repositioning >> Are there 15 repositioning actions or 15 m and therefore, one repositioning action
b)20 x 1 KA as load type Carrying >> In this case, 20 is obviously the distance
Hints on how the number should not be used and how it should be used
•not to determine distances
•not to determine frequencies when forces are applied (Sections 2 and 4) and not either when handling loads. The frequencies must be entered in the respective fields (dynamic actions for forces and number for load handling actions).
•however, it is used to determine the duration to detect static actions:
While frequency behaves just the other way around:
•to determine repetitions
•to determine distances
•not to determine static time portions.
