摘要

The opportunistic maintenance of a k-out-of-n:G system with imperfect preventive maintenance (PM) is studied in this paper, where partial failure is allowed. In many applications, the optimal maintenance actions for one component often depend on the states of the other components and system reliability requirements. Two new (τ,T) opportunistic maintenance models with the consideration of reliability requirements are proposed. In these two models. Only minimal repairs are performed on failed components before time τ and the corrective maintenance (CM) of all failed components are combined with PM of all functioning but deteriorated components after τ; if the system survives to time T without perfect maintenance, it will be subject to PM at time T. considering maintenance time, asymptotic system cost rate and availability are derived. The Results obtained generalize and unify some previous research in this area. Application to aircraft Engine maintenance is presented.
