Performance Efficiency

Performance efficiency is product of operating speed rate and the net operating rate. Operating speed rate of equipment refers to discrepancy between the ideal speed (based on equipment capacity as desired) and its actual operating speed.

Operating Speed Rate = Theoretical Cycle Time/ Actual Cycle Time

The net operating rate measures the maintenance of specified speed over a given period.

Net Operating Rate = Theoretical Processing Time/ Operation Time

= Processed Amount × (Actual Cycle Time/ Operating Time)

Therefore,

Actual Cycle Time = (Net Operating Rate × Operating Time)/ Processed Amount
