Reliability and condition-based maintenance for multi-component

Abstract: One
considers the condition-based maintenance policy of a multi-component deteriorating
system with stochastic dependence. Each component is
deteriorating according to a pure jump Lévy process. The failure of one
component may cause a shock modelled by a random increase the degradation
level of surviving components. Perfect inspections are carried out on the
system where highly deteriorated or failed components are perfectly replaced
and hence are restored to an as-good-as-new state. Nothing is done to the rest
of the components. For such a system, the evaluation of the reliability and the
assessment of the maintenance planning are quite complex due to the failure
dependence as well as the imperfect maintenance at the system level. The maintenances
costs in both the short-run and long-run horizons are derived using Markov
renewal theory. Numerical example is given to illustrate the applicability
of the proposed model. It can provide a reference for the decision-making when
developing maintenance policies.
