Overall Equipment Effectiveness. Improvement concept and indicator used in TPM. OEE measures the effective operational use of equipment regarding its potential. It can be calculated by multiplying 3 factors (OEE = Availability x Performance x Quality):
• Availability: stoppages such as breakdowns, changeovers, supply.
• Performance: losses due to micro-stoppages and low speed.
• Quality: losses due to scrap and rework.
