OPTIMAL MAINTENANCE DECISIONS FOR DIKES
Probability in the Engineering and Informational Sciences, 2000 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).

Optimal maintenance policies under different operational schedules [PDF]
, 2005 In the reliability literature, maintenance time is usually ignored during the optimization of maintenance policies. In some scenarios, costs due to system failures may vary with time, and the ignorance of maintenance time will lead to unrealistic results.

Linear and Nonlinear Preventive Maintenance Models [PDF]
, 2010 Preventive maintenance (PM) is a maintenance program with activities initiated at predetermined intervals, or according to prescribed criteria, and intended to reduce the probability of failure, or the degradation of the functioning of an item.

OPTIMAL MAINTENANCE OF SEMI-MARKOV MISSIONS
Probability in the Engineering and Informational Sciences, 2014 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 ...
