Total Time Failed—This statistic reports the total time the palletizer was in the Failed state
(i.e., was down due to failures).
The value of this statistic is the total time the palletizer variable Palletizer Name_State had
a value of Failed(1).
Total Time Changeover—This statistic reports the total time the palletizer was in the
Changeover state (i.e., was down due to changeovers).
The value of this statistic is the total time the palletizer variable Palletizer Name_State had
a value of Changeover(2).
Total Time Stopped—This statistic reports the total time the palletizer was in the Stopped
state (i.e., was down due to scheduled stops).
The value of this statistic is the total time the palletizer variable Palletizer Name_State had
a value of Stopped(5).
Total Time Speed Factor Greater Than 0—This statistic reports the total time the speed
factor of the palletizer was greater than zero.
Total Time Output Rate Greater Than 0—This statistic reports the total time the output
rate of the palletizer was greater than zero (i.e., the palletizer was actually filling or
emptying layers with units).
For palletizer-type equipment, it may be easier to think of this statistic as the total time the
input rate was greater than zero. The input and output rates of palletizers are always
equivalent.
Total Time Between Layers—This statistic reports the total time the output rate (input rate)
of the palletizer was zero because of the Time Between Layers specification.
Total Time Between Pallets—This statistic reports the total time the output rate (input rate)
of the palletizer was zero because of the Time Between Pallets specification.
U SAGE
Utilization—This statistic reports the percentage of time during the simulation run that the
palletizer was actually filling or emptying layers with units (i.e., the output rate was
greater than zero), or was not processing units because of the Time Between Layers and
Time Between Pallets specifications. Only scheduled time is considered. This statistic is
calculated as follows:
Utilization = (Total Time Output Rate Greater Than 0 + Total Time Betw. Layers + Total Time
Betw. Pallets)/( Simulation Run Length – Total Time Stopped)
where
Simulation Run Length is the duration of the simulation run and Total Time Stopped is the
reported total time the palletizer was in a scheduled stop.
