If you are a maintenance
professional or in maintenance
management, you may sometimes
wonder why it is so hard to
improve equipment reliability.
At first glance it may seem as a
simple task to improve equipment
reliability in plant where there
are obvious improvements to be
made. Let’s quickly list some of
the key actions that affect
equipment reliability and
reliability management.
Preventing failures or
prolonging life is possible by
improved lubrication, alignment,
balancing, operating procedures,
adjustment, detailed cleaning,
installation practices, good
engineering, and filtration.
Finding failures early can be
done by inspections such as
vibration analysis, looking,
feeling, smelling, oil analysis,
the list is endless. Once
failures are found we should
plan corrective actions and then
schedule the job, execute, and
record history for the job. In
order to plan well we need a
functioning store room and a
good technical database
including bill of materials and
technical specifications.
The above doesn’t seem so hard
to do, does it? But it is! The
truth is that most organisations
know what to do, but they rarely
do it! An analogy could be that
you are trying to lose weight,
fairly simple to find out what
to do (eat better and exercise),
but very hard to actually do.
He reason why it’s hard to
improve maintenance is that it’s
95% about getting people to
change their behaviour. The
planner needs to walk out to the
job and actually plan.
Operations need to count to more
than one when it comes to
priorities. Operations and
maintenance need to meet and
coordinate maintenance schedules
and production schedules. The
inspector need to do a detailed
job in inspecting equipment,
etc.
Improved process or
manufacturing capabilities can
usually be done by a rebuild of
equipment or manufacturing line,
which means it’s highly
dependent on technical
specifications, whereas
maintenance is about changing
people behaviour. That’s why
it’s hard to change equipment
reliability and relative simple
(but sometimes expensive) to
improve production. |
