Work out machine utilisation instantly with clear inputs, formula shown and shareable results.
Utilisation is running hours over available hours. Splitting idle time into planned downtime (maintenance, scheduled changeover) and unplanned downtime shows whether low utilisation is a maintenance policy or a reliability problem.
Utilisation
Utilisation % = Running hours / Available hours x 100
Effective utilisation
Effective % = Running hours / (Available - Planned downtime) x 100
No. Running a non-bottleneck at full utilisation just builds inventory, and running any asset flat out removes the slack needed to recover from disruption.
Utilisation is close to the availability element of OEE. OEE also multiplies in speed loss and quality loss.
