Preventive maintenance may be performed on a few selected components when a component fails. Importance measures can be used to identify the most important component that requires maintenance. However, this process involves two problems: (a) the preventive maintenance time of the selected component may be bigger than the maintenance time of the failed component; (b) the most important component may...
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<;...<;L(failure condition) is described. Then, a control limit maintenance policy is proposed where the system is inspected periodical with period T to identify the system state and the action...
The paper proposes a predictive maintenance model for the deteriorating system with semi-Markov process, and presents a method to determine the best inspection and maintenance policy together. Furthermore, the phase-type (PH) algorithm is put forward to measure the transition probability matrix analytical tractability. The results of numerical simulation show that the model and algorithm are effective...
