MTBF & MTTR
1. How often does a machine fail (MTBF)?
2. How long does it take to repair it (MTTR)?
These two questions may seem simple, however
are often abstracted within the forest of machinery
and clouded by human behavior.

SIMUL8 Corporation | SIMUL8.com | info@SIMUL8.com
One of the most debatable pieces of data
that goes into a simulation is the stochastic
behavior of machine downtime.

Advantages of Aggregate Values
• Used for predicting station/cell level
downtime based on components
• Reduces large data files
• Ease of communicating downtime figures
• Aligned with scope of model

Lock-out Procedure
A safety protocol which protects skilled trades
when entering a station or work cell. Each skilled
trade will have a named-lock, which will be
“locked” on an electrical panel before entering a
work cell for a repair. The protocol will have
several required steps to assure that all power is
off, assuring no machinery, robot, etc. movement.

A typical lock-out procedure might take 3 to 7 minutes to complete!

SIMUL8 Corporation | SIMUL8.com | info@SIMUL8.com
How do we account for the Lockout
Procedure?

A lockout procedure might be assumed
to be followed on the lengthier repairs
such as repair times that take 10
minutes or more.
