Overall Equipment Efficiency (OEE) is the primary performance metric of LiveTracking. Understanding the OEE calculation will help you measure the true performance of all lines across the factory floor.

Key Terms
Term | Definition |
Actual Time | The actual time it took to complete production |
Potential Time | Optimal duration to complete production |
Sensor Count | The count of goods that LiveTracking detected at the bottleneck/measurement point |
Finished Goods | The total amount of goods that come off the end of the line |
Good Output | Quality goods that can be sold/used elsewhere. LiveTracking uses Sensor Counts as Good Output to calculate OEE. LiveTracking will calculate OEE from Finished Goods instead of Sensor Count if there is a value present for that metric. |
Maximum Bottleneck Speed / Target Speed | This is the fastest speed at which the bottleneck process can operate. LiveTracking uses Target Speed for each product as the Max Bottleneck Speed. |
Calculations
This is how we calculate efficiency in LiveTracking:
Formula | Example |
Efficiency = Potential Time / Actual Time |
Given: Potential Time: 3.33hrs Actual Time: 10hrs Computation: = 3.33hrs /10hrs = 33.3% Efficiency |
Actual Time = Start Time of Run - End Time of Run |
Given: Start Time: 7:00 AM (0700 in 24hr format) End Time: 5:00 PM (1700 in 24hr format) Computation: = 1700 - 0700 = 10 hrs |
Potential Time = Good Output / Target Speed | Given:
Good Output: 10,000 Trays Target Speed: 50 Trays/min Computation: = 10,000 Trays / 50 Trays/min = 200 min = 3.33hrs |
