What this term means in maintenance
Equipment uptime is the duration or percentage of required time during which an asset is operating or available for operation.
Basic percentage
Uptime percentage = Uptime ÷ Required time × 100
Practical example
A line is required for 100 hours and is available for 94 hours.
Uptime = 94%
Uptime versus availability
The terms are sometimes used similarly, but organizations should define whether idle-but-available equipment counts as uptime.
Use of uptime
It supports production review, reliability analysis, maintenance performance, and customer service.
Common mistake
Using calendar time instead of required operating time can distort the percentage.
