Piecewise deterministic Markov process for condition-based imperfect maintenance models [PDF]
Reliability Engineering & System Safety, 2022 In this paper, a condition-based imperfect maintenance model based on piecewise deterministic Markov process (PDMP) is constructed. The degradation of the system includes two types: natural degradation and random shocks.

Interval optimization of civil aircraft imperfect preventive maintenance based on availability
Hangkong gongcheng jinzhan, 2023 The initial preventive maintenance interval recommended by civil aircraft manufacturers usually does not consider the operators' environment and maintenance capacity difference.It is difficult to achieve the optimal state of availability while meeting ...

Imperfect Maintenance Policy for a Two-Machine One-Buffer System Based on Markov Decision Process
Shanghai Jiaotong Daxue xuebao, 2021 To solve the problem of machine maintenance optimization of degraded systems, the preventive maintenance policy of a two-machine one-buffer production system is studied. First, random degradations of both machines are considered.

A comprehensive framework from real‐time prognostics to maintenance decisions
IET Collaborative Intelligent Manufacturing, 2021 Studying the influence of imperfect prognostics information on maintenance decisions is an underexplored area. To bridge this gap, a new comprehensive maintenance support system is proposed. First, a survival theory‐based prognostics module employing the

Imperfect Preventive Maintenance Policies With Unpunctual Execution [PDF]
IEEE Transactions on Reliability, 2020 Traditional maintenance planning problems usually presume that preventive maintenance (PM) policies will be executed exactly as planned. In reality, however, maintainers often deviate from the intended PM policy, resulting in unpunctual PM executions that may reduce maintenance effectiveness.
