10. OVERALL EQUIPMENT EFFECTIVENESS (OEE)

11. What is Overall Equipment Effectiveness (OEE) OEE measures the efficiency of the machine during its loading time. OEE is calculated from three underlying factors: Availability Performance Quality Each of these factors represents a different perspective of how close your manufacturing process is to perfect production

12. Availability a comparison of the potential operating time and the time in which the machine is actually making products . Performance a comparison of the actual output with what time the machine should be producing in the same time. Quality a comparison of the number of products made and the number of products that meet the customer’s specifications. T h r e e F a c t o r s o f O E E

13. Why is OEE important? OEE is expressed as a percentage it gives a complete picture of the machine’s “health ” Effectiveness focuses on the equipment, not the person OEE measurement helps us to direct improvement efforts on the equipment or process
