Opportunistic Behavior in Road Maintenance Markets
Transportation Research Record: Journal of the Transportation Research Board, 2009Gaming simulation has frequently proved a valuable method of exploring future scenarios in various fields of policy making. Researchers applied gaming to examine the long-term consequences of contracting out the maintenance of roads. The game, Road Roles, simulates this new situation at an abstract level. Instead of traditional prescriptive contracts,

Reinforcement learning for opportunistic maintenance optimization
Production Engineering, 2018Intelligent systems, that support the maintenance of production resources, offer real-time data-based approaches to optimize the maintenance effort and to reduce the usage of resources within production systems. However, unused potentials remain regarding maintenance schedules with minimal opportunity costs of the measures taken.

Competing risks and opportunistic informative maintenance
Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability, 2009The present paper makes a link between the literature on competing risks and that of opportunistic maintenance. Three models for competing risk involving censoring through opportunistic maintenance are discussed. One is an existing opportunistic maintenance model, one is a new opportunistic variant on an existing competing risk model, and the third is

Reliability Engineering & System Safety, 2021
Abstract A proper maintenance schedule is an effective solution to reduce failure and keep systems in good condition. Reliability evaluation and maintenance model are two key issues for schedule optimization. The delay time theory is applied to evaluate reliability for a system by using sufficient inspection data and insufficient failure data.

Opportunistic maintenance (OM) as a new advancement in maintenance approaches
Journal of Quality in Maintenance Engineering, 2014Purpose – This paper reviews the literature on opportunistic maintenance (OM) as new advance maintenance approach and policy. The purpose of this paper is to conceptually identify common principle and thereby provide absolute definition, concept and characteristics of this policy.

Opportunistic maintenance for wind turbines considering imperfect, reliability-based maintenance
Renewable Energy, 2017Abstract Corrective maintenance and time-based maintenance have been widely employed in wind farms. However, the actual maintenance strategy is much more complex and diverse, and also maintenance actions do not always return the system to “as good as new” condition. Moreover, dependencies exist in multi-component systems, and it is more economical to

Opportunistic Maintenance Policies for Multi-Components Systems
2012This chapter provides some contributions for opportunistic maintenance optimization of multi-component system in the arising context of on-line monitoring and strong interactions between components. The key point is, on one hand, to model and integrate different kinds of dependencies (stochastic dependence, structural dependence and economic dependence)

Opportunistic maintenance using genetic algorithms
Journal of Quality in Maintenance Engineering, 2004Opportunistic maintenance gives the maintenance crew an opportunity to replace or repair those items, which are found to be defective or needs replacement in the immediate future, during the maintenance of a sub‐system or a module. This paper tries to address the questions of how to decide whether a particular item needs opportunistic maintenance, and ...

Maintenance Scheduling of Transmission Bays Considering Selective Opportunistic Maintenance Strategy
2019 IEEE 3rd International Conference on Green Energy and Applications (ICGEA), 2019Unlike previous research which didn't consider opportunistic maintenance between dependent power equipment in power system, opportunistic maintenance strategy is modeled and the impact of opportunistic maintenance strategy on maintenance scheduling of transmission bays is investigated in this paper.

A simulation model for opportunistic maintenance strategies
1999 7th IEEE International Conference on Emerging Technologies and Factory Automation. Proceedings ETFA '99 (Cat. No.99TH8467), 2003An opportunistic maintenance strategy is proposed to maintain a production line consisting of k nonidentical processors and without intermediary stocks. Operational characteristics of processors are degraded with usage. In this strategy, preventive maintenance activities are combined with corrective ones as soon as a certain technical and economical ...
