In the context of OEE, ‘availability’ is determined by which of the following?

The definition of availability in the context of Overall Equipment Effectiveness (OEE) revolves around how much time a machine is available for production compared to the total scheduled production time. This is calculated by considering both the scheduled production time and any downtime, specifically downtime due to maintenance or other stoppages.

Scheduled production time represents the total time a machine is supposed to be operational during a given period. However, this time is impacted by downtime occurrences, which include maintenance, breakdowns, or any other interruptions that prevent the machine from running.

Thus, availability is determined by the ratio of the actual operating time of the equipment to the scheduled production time, where downtime is subtracted from the total scheduled time. Considering both aspects—scheduled production time and the impact of maintenance or other downtimes—is crucial for accurately calculating equipment availability.

This reasoning supports the choice that combines both scheduled production time and downtime due to maintenance, clearly defining availability within the OEE framework.
