Most maintenance-optimisation models assume an infinite planning horizon and suppose that the failure process is … information (such as a variable use of components and the occurrence of maintenance opportunities). With numerical experiments we … stationary-planning method with the costs according to an approach which can adapt this long-term plan to dynamically changing …

In this paper we review the literature on multi-component maintenance models with economic dependence. The emphasis is … Parlar (1991). The classification scheme that we choose is primarily based on the various options of grouping maintenance … activities: grouping either corrective or preventive maintenance actions, or combining preventive maintenance activities with …

Nowadays railway companies are confronted with high infrastructure maintenance costs. Therefore good strategies are … needed to carry out these maintenance activities in a most cost effective way. In this paper we solve the preventive … maintenance scheduling problem (PMSP) using genetic algorithms, memetic algorithms and a two-phase heuristic based on …
