Maintenance scheduling of a protection system subject to imperfect inspection and replacement

Berrade, MD; Cavalcante, CAV; Scarf, PA

Abstract

An inspection and replacement policy for a protection system is described in which the inspection process
is subject to error, and false positives (false alarms) and false negatives are possible. We develop two
models: one in which a false positive implies renewal of the protection system; the other not. These models
are motivated by inspection of a protection system on the production line of a beverage manufacturer.
False negatives reduce the efficiency of inspection. Another notion of imperfect maintenance is also modelled:
that of poor installation of a component at replacement. These different aspects of maintenance
quality interact: false alarms can, in a worst case scenario, lead to the systematic and unnecessary
replacement of good components by poor components, thus reducing the availability of the system.
The models also allow situations in which maintenance quality differs between alternative maintainers
to be investigated.
