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,

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 and delayed maintenance as strategies for sustainable maintenance practices
International Journal of Quality & Reliability ManagementPurposeOpportunistic and delayed maintenances are increasingly becoming important strategies for sustainable maintenance practices since they increase the lifetime of complex systems like aircrafts and heavy equipment. The objective of the current study is to quantify the optimal time window for adopting these strategies.Design/methodology/approachThe ...

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 ...

Distributed Maintenance of Cache Freshness in Opportunistic Mobile Networks
2012 IEEE 32nd International Conference on Distributed Computing Systems, 2012Opportunistic mobile networks consist of personal mobile devices which are intermittently connected with each other. Data access can be provided to these devices via cooperative caching without support from the cellular network infrastructure, but only limited research has been done on maintaining the freshness of cached data which may be refreshed ...

A framework for the choice of the opportunistic maintenance policy in industrial contexts
2013 IEEE International Conference on Industrial Engineering and Engineering Management, 2013Aim of the present paper is to propose a framework for the choice of the opportunistic maintenance models for applications in real contexts. The paper explores firstly the scientific literature on opportunistic maintenance in order to obtain a multi-criteria classification of the main existing models.

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.

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 ...

An opportunistic maintenance policy for offshore wind farms
Ocean Engineering, 2020Abstract An opportunistic maintenance policy for offshore wind farms is introduced, considering imperfect maintenance and the weather window effect. Each wind turbine is regarded as a multi-component system divided into several assemblies. When one unit fails or reaches its critical degradation state, there is an opportunity to implement preventive ...
