Overall Equipment Effectiveness (OEE)

The Combined Measurement of Equipment Availability, Performance Rate and Quality Rate: A key measurement in “Total Productive Maintenance” (TPM)

Formula: Machine Availability X Performance Rate X Quality Rate


Machine Availability: Is The Actual Time Left For Production After You Subtract All Planned Downtime.

Performance Rate: Is The Measure Of “How Well The Machine Was Running When It Was Running.”

Quality Rate: Tells Us How Many Good Parts VS. Defective Parts A Machine Has Produced During The Time It Was Running.

OEE is an essential measurement for determining the effectiveness of your equipment and beginning to understand where up-time improvements are possible.
