What is machine availability?

Machine availability measures the proportion of time a machine is actually in operation compared to the time it should be in operation. High machine availability means that a machine can produce more frequently and requires less time for maintenance and repairs. Low machine availability, on the other hand, can lead to delays and downtime in production.

How to calculate the machine availability?

Machine availability is calculated by dividing the actual operating time by the planned operating time.


Planned operating time: 500 hours

Actual operating time: 480 hours

480/500= 0.96 or 96%.

The machine availability is 96%.

How to increase machine availability?

Machine availability is increased by reducing planned and unplanned downtime. Through maintenance strategies such as predictive maintenance, maintenance measures can be planned on the basis of data analyses in order to prevent failures and thus increase machine availability.
