Station factors are used if a station (with identical work contents) occurs several times within a line.
They can be defined in the tree view of a balancing for stations in the corresponding column. See also: How do I assign a factor?
The default setting is 1.
The factor is the same for all product variants. It is therefore NOT possible to use different station factors for each product variant!
The times of all assigned elements are divided virtually; for example, with a factor of 2, the time of the assigned work content is halved.
Station factor for cross-station operators
In this case, the entered factor is applied to all assignments of an operator at the station. All other operator instances at other stations remain unchanged.
Effects of station factors (hereafter "n") on the assignment
Assigning a station factor affects the time type of the assigned elements and the HWD posture transition.
Calculation: Time type (regular) / n = time type (new)
Change in display
The factor used is shown in front of the station in the assignment graphic.
Example: |
|---|
The Pre-Assembly station was assigned factor 2.  Display of a station factor in the assignment graphic |
Will also be recalculated
▪ Time type (total)
▪Time type (total) * pieces
▪Sum times at all assignments
▪Sum time at operator including load
▪Sum time at station including load
The graphic also displays the adjusted times.
Example: |
|---|
There is one station (S1) with one operator (W1). The assigned element is B1. The station has a station factor of 2. B1 has a tg of 10 TMU and a factor of 4. tg total = 10 TMU * 4 * 1/2 = 20 TMU Cycle time = tcycle |
Effect of station factors on ergonomics
The EAWS evaluation is carried out with a modified cycle time, a modified number of cycles and the original (i.e. unchanged) element time.
Calculation:
Cycle time (regular) * n = cycle time new
Number of cycles (regular) /n = number of cycles (new)
The ergonomics allowance remains unchanged.
