Risk Based Maintenance policies for SMART devices

Sammanfattning:
Maintenance activities are commonly organized into scheduled and
unscheduled actions. Scheduled maintenance is undertaken during
pre-programmed inspections. Such maintenance operations try to minimize
the risk of deterioration based on a priori knowledge of failure
mechanisms and their timing. However, in complex systems it is not
always possible to schedule maintenance actions to mitigate all
undesired effects, and SMART systems, which monitor selected parameters,
propose actions to correct any deviation in normal behavior.
Maintenance decisions must be made on the basis of accepted risk.
Performed or not performed scheduled tasks as well as deferred
corrective actions can have positive or negative consequences for the
company, technicians and machines. These three risks should be properly
assessed and prioritized as a function of the goals to be achieved. This
paper focuses on how best practices in risk assessment for human safety
can be successfully transferred to risk assessment for asset integrity.
