Total Time Speed Factor Greater Than 0—This statistic reports the total time the speed
factor of the machine was greater than zero.
Total Time Output Rate Greater Than 0—This statistic reports the total time the output
rate of the machine was greater than zero.
U SAGE
Utilization—This statistic reports the percentage of time during the simulation run that the
machine was actually producing loss and/or good product (i.e., the output rate was greater
than zero). Only scheduled time is considered. This statistic is calculated as follows:
Utilization = (Total Time Output Rate Greater Than 0)/( 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 machine was in a scheduled stop.
C OST
Equipment Operating Cost—This statistic reports the fixed operating cost of the machine
over its scheduled time. This statistic is calculated as follows:
Equipment Operating Cost = (Simulation Run Length – Total Time Stopped) * (Cost/Hour)
where
Simulation Run Length is the duration of the simulation run, Total Time Stopped is the reported
total time the machine was in scheduled stops, and Cost/Hour is the cost factor entered in the
Costs dialog box.
Cost of Good Product—This statistic reports the variable cost of producing good product
at the machine. This statistic is calculated as follows:
Cost of Good Product = Total Good Units Produced * Cost/Good Unit
where
Total Good Units Produced is the reported total of good units produced by the machine, and
Cost/Good Unit is the cost factor entered in the Costs dialog.
Cost of Lost Product—This statistic reports the variable cost of producing lost product at
the machine. This statistic is calculated as follows:
Cost of Lost Product = Total Units Lost * Cost/Lost Unit
where
Total Units Lost is the reported total of units lost at the machine, and Cost/Lost Unit is the cost
factor entered in the Costs dialog box.
