Optimal Predictive Maintenance Policy for Multi-State Deteriorating System under Periodic Inspections
This paper proposes a predictive maintenance model for multi-state Markov deteriorating system. In this model, a system subject to aging and fatal shocks and with states 0(initial condition)<1<2<...
