Abstract
Last-minute maintenance planning is often undesirable, as it may cause downtime
during operational hours, may require rescheduling of other activities, and
does not allow to optimize the management of spare parts, material, and
personnel. In spite of the aforementioned drawbacks of last-minute planning,
most existing methods plan maintenance activities at the last minute. In this
paper, we propose a new strategy for timely maintenance planning in
multi-component systems. As a first step, we determine for each system
component independently the most appropriate maintenance planning strategy.
This way, the maintenance decisions can be tailored to the specific situations.
For example, conservative maintenance decisions can be taken when the risk
tolerance is low, and maintenance decisions can be made timely when we can
accurately predict future degradation behavior. In the second step, we optimize
the maintenance plan at the system level. Here, we account for economic and
structural dependence with the aim to profit from spreading or combining
various maintenance activities. The applicability of the method is demonstrated
on a railway case. It is shown how the different cost functions (e.g. costs of
maintenance, downtime, and failure) influence the maintenance decisions.
