OEE can be calculated by multiplying Availability, Performance, and Quality percentages.

• Calculate Availability by dividing Operating Time by Planned Production Time.

• Calculate Performance by dividing Actual Production by Maximum Production.

• Calculate Quality by dividing Good Units by Total Units Produced.

• Multiply Availability, Performance, and Quality percentages to get OEE.

The laws that govern the behavior of energy in a system.

• There are three laws of thermodynamics.

• The first law states that energy cannot be created or destroyed, only transferred or converted.

• The second law states that the total entropy of a closed system will always increase over time.

• The third law states that as the temperature of a system approaches absolute zero, the entropy of the system approaches a minimum.

• These l...read more
