Total working hours = hours per shift x shifts per day
Loading Time = Total Working Time-Planned Stop Time
Running Time = Loading Time-Unplanned Stop Time
Time running efficiency = running time/loading time x 100%
Speed and operating efficiency = benchmark production cycle/actual production cycle x 100%
Effective operation efficiency = actual production cycle x total production/operation time x 100%
Performance and operational efficiency = benchmark production cycle x total production/operational time x 100%
Yield = (total output-number of defective products)/total output x 100%
Comprehensive efficiency = time operation efficiency x performance operation efficiency x output
Short stop or idling time = running time-total output x actual production cycle
"Monthly average actual production cycle = sum (daily actual production cycle × total output)
Divided by the total monthly output "
