Cycle Time (2) to (3) = 80 seconds
Average Cycle Time = (80 + 90) / 2 = 85 seconds
Completed Units Gauge and Label
Filter Supported – Factory Line/Process Point
Subtract the number of units that have failed, from the number of units processed through the
point, to derive at the number of completed units. If the number of completed units is greater than
the job quantity, the completed quantity is reduced to the job quantity.
Cycle Count Numeric Indicator
Filters Supported – Process Point
The Cycle Count gauge simple counts every item that passes through the point. No adjustment is
made based on the status of the unit passing through the station.
OEE Availability (Overall Equipment Effectiveness) Gauge and Indicator
Filters Supported – Factory Line/Process Point
For a brief overview of OEE please see section OEE Overview below.
This value reports the percentage of up-time achieved during planned production time during a
specified time window. Planned production time is considered all time within the specified time
window if zero planned production times have been defined. If one or more planned production
times have been defined then the total planned production time is the time within the specified time
window that has been explicitly identified as being production time. Consider a planned production
window has been defined as from 8:00am through 12 noon. If the specified time window for which
OEE Availability is to be reported is 3 hours and the current time is 11:30am then the planned
production time is 3 hours as the time window for reporting extends from 8:30am (11:30am – 3
hours) through 11:30am. However if the time is 8:30am then the planned production time would be
30 minutes as 5:30am through 8:00am was unplanned and only from 8:00am through 8:30am was
planned.
Taking this a stage further, if the machine was down from 8:00Am through 8:30am then when
reporting OEE at:
8:30AM Planned Production Time = 30 minutes
Operating Time = 0 minutes
OEE Availability = (Operating Time / Planned Production Time)
= (0 / 30)
= 0 (0%)
11:30AM Planned Production Time = 180 minutes
Operating Time = 150 minutes
OEE Availability = (Operating Time / Planned Production Time) x 100
= (150 / 180) x 100
= 0.8333 (83.33%)
Operating time is calculated by reviewing machine state information for the planned production
time window and summing up the duration of each machine state which is designated as operating
