Figure 6.13 Miller 201 equipment history record: downtime and faults
Example OEE calculation
The following example uses the data for the Tuesday of week 17 on the
equipment history record of Table 6.2.
Availability
uptime
availability =
planned availability
uptime = planned availability - downtime
downtime = unplanned stoppages + changeovers = 115 + 12 = 127 min
Therefore
uptime = 910 - 127 = 783 min
783
availability = - = 86.0%
910
Performance
completed cycles
performance =
planned cycles
completed cycles = 203
-
planned cycles = uptime - --
783 - 261
standard cycle time 3
Therefore
203
performance = - = 77.7%
