Chapter 5 Understanding Report Templates
58 Rockwell Automation Publication RPTEXP-UM001H-EN-P-June 2014
Calculations used by Report Expert to obtain values in the resulting
report:
Uptime % = RunningTime/AvailableTime
Throughput % = (TotalParts x IdealCycleTime) /
RunningTime
Quality % = GoodParts / Total Parts
OEE % = Uptime x Throughput x Quality
Or:
This reduces to:
NOTE
Typically, the OEE calculation will be performed over a time range with
numerous IdealCycleTime values. In this case, the calculation is done for
each unique IdealCycleTime using the GoodParts and AvailableTime
during that IdealCycleTime. Each individual calculation is then
multiplied by its fraction of the TotalAvailableTime
(AvailableTime/TotalAvailableTime) and then summed together.
The following formula illustrates the calculation with multiple
IdealCycleTimes:
where:
ICT = IdealCycleTime
GP = GoodParts
