Hi,

The key figure MTTR is calculated in hours.

First breakdown 10 hours

Second breakdown 05 hours

Number of breakdowns 02

MTTR = 10 + 5 / 2 = 7.5 hours

The key figure MTBR is calculated in hours.

The following example shows how the MTBR is calculated:

Acquisition date of pump A 01.01.94

First breakdown 10.01.94

Downtime 10 hours

Second breakdown 20.01.94

Downtime 5 hours

Number of breakdowns 2

MTBR = (19 * 24 - 10) / 2 or X + Y (hr) / 2

= (456 - 10) / 2 or (216 + 240 - 10) / 2

= 223 hours

Example: Average Duration Between Two Machine Breakdowns (MTBR)
