Abstract:In today's world, many remotely operated systems are becoming ever more complex and the number of components in these systems keeps on growing. Examples include water pump systems for irrigation or mining purposes, off-shore power generation systems --the focus application area in this talk. Such systems are typically mission-critical for their users. Hence, it is of utmost importance to keep them in operating condition via well-designed maintenance policies. It makes sense for such policies to make use of whatever information is available no matter how limited.  This approach is commonly labeled as condition-based maintenance (CBM) planning. In this talk, we will present a novel methodology to manage maintenance interventions as well as spare part quantity decisions for such systems.  Our methodology is based on reducing the state space of the multi-component system and optimizing the resulting reduced-state Markov decision process via a linear programming approach. This methodology is highly scalable  and capable of solving large problems that cannot be approached with the previously existing solution procedures due to the curse of dimensionality.
