Maintenance Optimization for Repairable Deteriorating Systems under Imperfect Preventive Maintenance
Mathematics, 2019 This study deals with the preventive maintenance optimization problem based on a reliability threshold. The conditional reliability threshold is used instead of the system reliability threshold.

Modelling and optimizing sequential imperfect preventive maintenance [PDF]
Reliability Engineering and System Safety, 2009 Abstract This paper deals with the problem of scheduling imperfect preventive maintenance (PM) of some equipment. It uses a model due to Kijima in which each application of PM reduces the equipment's effective age (but without making it as good as new).

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.

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 ...

Age Based Overhaul Policy for Multiple Repairable Systems with Imperfect Maintenance: Case Study of Aero Engines [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2021 Reliability analysis of complex multiple repairable systems (MRS) such as aero engines, rolling stocks and nuclear power plants has always been an area of interest for the research fraternity. An appropriate age based overhaul maintenance policy for such

Really Ageing Systems Undergoing a Discrete Maintenance Optimization
Mathematics, 2022 In general, a complex system is composed of different components that are usually subject to a maintenance policy. We take into account systems containing components that are under both preventive and corrective maintenance.
