Operating rate
The operating rate means the amount of time in a time frame (shift,day,etc.) that a machine is used to make something.
Operational Availability
The operational availability is the fraction of time that a machine function properly when needs.
The trap of chasing high operating rate
Keeping a high operating rate sounds effective on the surface,but it often causes the waste of overproduction when we run machines without relation to any need of the processes downstream. The operating rate may be high or low according to the need of its customers,or the processes downstream.
The ideal operational availability is 100%.
A high operating rate is not necessarily desirable,but the ideal operational availability
rate should be 100%.
