Purpose To be able to continuously provide affordable services consumers, managers of critical infrastructure (CI) maintenance supply networks have balance investments in resilience with costs. At the same time, CI providers need consider factors that influence such as geographical spread or location network. This study aims contextualize chain knowledge by exploring how resource configurations...
Maintenance is an important activity in industry as it reduces costs and enhances availability. This can be done either to revive a system/component or to prevent it from breaking down. The increasing need for reliability has led maintenance strategies to evolve from corrective to condition-based and predictive maintenance. The key process of the latter is prognostics and health management, a t...
Bayesian Belief Networks (BBNs) are a pow erful formalism for reasoning under uncer tainty but bear some severe limitations: they require a large amount of information be fore any reasoning process can start, they have limited contradiction handling capabil ities, and their ability to provide explana tions for their conclusion is still controversial. There exists a class of reasoning syste...
We investigate the problem of scheduling the maintenance of edges in a network, motivated by the goal of minimizing outages in transportation or telecommunication networks. We focus on maintaining connectivity between two nodes over time; for the special case of path networks, this is related to the problem of minimizing the busy time of machines. We show that the problem can be solved in polyn...
