U SAGE
Percent Scheduled—This statistic reports the percentage of total simulation time that the
operator was available for equipment repairs, changeovers, or scheduled stops. Essentially,
this is the percentage of time that the operator was on duty.
For example, if an operator is on duty for 440 minutes out of 480 simulated minutes, the
availability percentage of the operator is 440/480 or 91.67%.
Scheduled Utilization—This statistic reports the percentage of scheduled time that the
operator was actually busy working on a failure, changeover, or stop.
For example, suppose an operator was on-duty for 440 minutes out of 480 simulated
minutes. If the operator was actually busy for 120 of those 440 minutes, then the
operator’s scheduled utilization is 120/440 = 27.27%.
C OST
Total Cost—This statistic reports the fixed operating cost of the operator over his or her
scheduled time. The scheduled time of an operator includes lunch and break times, but not
off-duty time. This statistic is calculated as follows:
Total Cost = (Simulation Run Length – Off-Duty Time) * (Cost/Hour)
where
Simulation Run Length is the duration of the simulation run and Off-Duty Time is the total time
the operator is off-duty.
Operator Group statistics
The Category Overview statistics for an operator group are described below.
D ESCRIPTION
Number In Group—This statistic reports the number of operators in the operator group.
U SAGE
Number Scheduled—This statistic reports the maximum, minimum, and average number
of operators in the group that were on duty during the simulation.
Percent Scheduled—This statistic reports the average percentage of the group that was on
duty during the simulation. This statistic is calculated as follows:
Percent Scheduled = 100 * (Average Number Scheduled/Number Operators in Group)
Number Busy—This statistic reports the maximum, minimum, and average number of
operators in the group that were busy during the simulation.
