Overall Equipment Effectiveness - Availability Tools
Introduction
The ‘Availability’ tool helps to isolate operational versus equipment issues
and allows the user to
track the equipment downtime and view the
downtime statistics.
The pareto of faults that allows the analysis of runtime measurement data,
helps the user to
understand and eliminate the more frequent causes of
both equipment and operational
downtime.
The availability shows two basic availability metrics simultaneously:
•
Equipment Availability
•
Operational Availability
Equipment availability is the same and equal or more than operational
availability.
Note: Operational Availability can be changed between two separate production
time proxies as
required by the user: "Power On" and "Running" mode. Please
see “Operational Availability” on
page E-2 for further details
Equipment Availability
Equipment Availability = 1 -
Equipment Downtime
Equipment Total Time
Where,
‘Equipment Total Time’ is the total amount of time for which the
equipment is turned On (has
power applied). If the equipment is powered
down when a fault is active, the equipment total
time also includes the
amount of time for which the equipment is off.
