How to Calculate and Improve Machine Availability

Availability = Run Time / Planned Production Time. For example, if a machine runs for 8 hours, with 4 hours of downtime, during a 12-hour shift, then the availability for that machine is 66.6%. One issue with calculating equipment availability through traditional means is that each instance must be recorded.
