OPTIMAL MAINTENANCE DECISIONS FOR DIKES
To protect the Dutch polders against flooding, more than 2500 km of dikes have been constructed. Due to settlement, subsoil consolidation, and relative sea-level rise, these dikes slowly sink “away into the sea” and should therefore be heightened regularly (at present, every 50 years).

Proposed procedure for optimal maintenance scheduling under emergent failures
Production lines are usually subjected to emergent machine failures. Such emergent failures disrupt pre-established maintenance schedules, which challenge maintenance engineers to react to those failures in real time.

Interval optimization of civil aircraft imperfect preventive maintenance based on availability
The initial preventive maintenance interval recommended by civil aircraft manufacturers usually does not consider the operators' environment and maintenance capacity difference.It is difficult to achieve the optimal state of availability while meeting ...

Optimal Maintenance Policy for Corroded Oil and Gas Pipelines using Markov Decision Processes
This paper presents a novel approach to determine optimal maintenance policies for degraded oil and gas pipelines due to internal pitting corrosion. This approach builds a bridge between Markov process-based corrosion rate models and Markov decision ...

OPTIMAL MAINTENANCE OF SEMI-MARKOV MISSIONS
We analyze optimal replacement and repair problems of semi-Markov missions that are composed of phases with random sequence and durations. The mission process is the minimal semi-Markov process associated with a Markov renewal process. The system is a complex one consisting of non-identical components whose failure properties depend on the mission ...
