Optimal selective maintenance decisions for large serial k-out-of-n: G systems under imperfect maintenance

Reliability Engineering and System Safety, 2018
The selective maintenance problem (SMP) arises in many large multicomponent systems which are operated for consecutive missions interspersed with finite breaks during which only a selected set of component repairs or replacements can be carried out due ...

Model for the Selection of Predictive Maintenance Techniques

INFOR: Information Systems and Operational Research, 2007
Abstract A Predictive Maintenance Program can provide significant benefits to industrial plants in the areas of security, quality and availability. However, Predictive Maintenance Programs have lacked analysis in matters related to their set up, management and control.

Handling the epistemic uncertainty in the selective maintenance problem

Computers & industrial engineering, 2020
Nowadays, both continuous and discontinuous operating systems require higher and higher reliability levels in order to avoid the occurrence of dangerous or even disastrous consequences.

Selective Maintenance under Uncertainty

PHM Society Asia-Pacific Conference, 2017
In this paper, a new multi-objective robust selective maintenance model is formulated by considering the uncertainties produced by imperfect inspections. The resulting optimization problem aims at maximizing the expectation of the probability of a repaired system completing a mission and simultaneously minimizing its variance.

Selection and Maintenance of the Aim

1997
The simple fact is that few conscious actions are taken without a specific purpose. If one raises a hand it may be in greeting, in salute, or perhaps to shade one’s eyes. Almost always there is a purpose. To go to war — a war in which countless lives will be lost and on which may depend the future of a nation, or the freedom and lifestyle of its people

Sexual selection and the maintenance of sexual reproduction

Nature, 2001
The maintenance of sexual reproduction is a problem in evolutionary theory because, all else being equal, asexual populations have a twofold fitness advantage over their sexual counterparts and should rapidly outnumber a sexual population because every individual has the potential to reproduce.

Robust selective maintenance strategy under imperfect observations: A multi-objective perspective

IISE Transactions, 2019
Selective maintenance, as a pervasive maintenance policy in both military and industrial environments, aims to achieve the maximum success of subsequent missions under limited maintenance resources by choosing an optimal subset of feasible maintenance ...

An Exact Method for Solving Selective Maintenance Problems Considering Imperfect Maintenance

2016 International Conference on Intelligent Networking and Collaborative Systems (INCoS), 2016
In the past few decades, analytical models for maintenance optimization have been extensively investigated. As research continues, the cases considered during the mathematical modeling are much more practical, as well as complex, which brings many difficulties for solution. In this paper, we present an exact method for solving the selective maintenance
