                    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%
                                                 261
