How is equipment availability as a factor of OEE calculated?

Equipment availability as a factor of Overall Equipment Effectiveness (OEE) is calculated by dividing the actual operation time by the planned operation time. This calculation provides insight into how often the equipment is operational compared to the time it was scheduled to be available for production.

This method considers any downtime that may occur during the planned production schedule, including both unplanned (breakdowns or failures) and planned (scheduled maintenance) downtimes. The resulting ratio helps to understand the efficiency of the equipment in terms of availability, which is a critical component of OEE.

While other options address aspects of operational effectiveness, they do not accurately capture the specific relationship of actual operational time to planned operational time, which is essential for determining equipment availability. This distinction is crucial for monitoring and improving manufacturing performance.
