The value of this statistic is the last value of the palletizer variable Palletizer
Name_NumFailures.
Number of Changeovers—This statistic reports the number of changeovers that occurred
at the palletizer.
The value of this statistic is the last value of the palletizer variable Palletizer
Name_NumChangeovers.
Number of Scheduled Stops—This statistic reports the number of scheduled stops that
occurred at the palletizer.
The value of this statistic is the last value of the palletizer variable Palletizer
Name_NumScheduledStops.
Number of Blockages—This statistic reports the number of blockages that occurred at the
palletizer (i.e., number of times speed factor equaled 0 for reason other than failure,
changeover, or scheduled stop).
P ERFORMANCE
Average Speed Factor Greater Than 0—This statistic reports the average speed factor of
the palletizer when the palletizer was running (i.e., had a speed factor greater than zero).
The average speed factor is equivalent to the average run speed of the palletizer divided
by its nominal run speed.
The value of this statistic is the time-weighted average of the palletizer variable Palletizer
Name_SpeedFactor over the time the palletizer had a speed factor greater than zero.
Average Output Rate Greater Than 0—This statistic reports the average output rate of the
palletizer when the output rate was greater than zero.
The value of this statistic is the time-weighted average of the palletizer variable Palletizer
Name_OutputRate over the time the palletizer had an output rate greater than zero.
Average Output Factor—This statistic reports the ratio of the Average Output Rate
statistic to the nominal run speed of the palletizer. This statistic is calculated as follows:
Average Output Factor = (Average Output Rate) / (Nominal Run Speed * Units/Layer)
where
Nominal Run Speed (in layers/basetimeunit) and Units/Layer are run parameters entered in the
main dialog.
Yield—This statistic reports the efficiency of the palletizer for processing good product.
This statistic is calculated as follows:
Yield = ((Total Good Units Produced)/(Total Units Processed)) * 100
