Performance

The performance efficiency component of OEE measures a system's ability to produce at the target production rate:

Performance = Total Output / Target Output

In MES, an entity's performance during a time period is based solely on the production reported on the entity only while the entity is in a Runtime utilization state. If multiple work orders are run during the period, producing different items with different unit of measures, the performance calculation is based purely on item production counts with no effort to convert units of measure.
