In other words, it is a measure of the contribution of the current equipment to the added-value generation time, based on the overall consideration of the time/speed performance and non-defective ratio of the equipment.
Availability = (Loading hours – Downtime) + Loading hours
Performance rate = Net utilization rate X Speed utilization rate
Net utilization rate means continuance, and minor stoppage losses are to be calculated.
= Output X Actual cycle time + (Loading hours – Downtime)
Speed utilization rate indicates speed difference
= Standard cycle time + Actual cycle time
Quality products rate = No. of quality products + Input volume
No. of quality products = Input volume – (Start-up defect volume + No. of process defects + No. of rework causes)
Overall Equipment Efficiency = Availability X Performance rate X Quality products rate
