“…In addition, they introduced previous case studies in system monitoring and control. Furthermore, Grobal et al [13] introduced the initial architecture for CBM framework, which was being realized in a joint project with SAP research. They mentioned several aspects of CBM: identification of indicators, measurement of indicators, modeling of indicators, forecasting of indicators, and decision making.…”
In the case of a high-valuable asset, the Operation and Maintenance (O&M) phase requires heavy charges and more efforts than the installation (construction) phase, because it has long usage life and any accident of an asset during this period causes catastrophic damage to an industry. Recently, with the advent of emerging Information Communication Technologies (ICTs), we can get the visibility of asset status information during its usage period. It gives us new challenging issues for improving the efficiency of asset operations. One issue is to implement the Condition-Based Maintenance (CBM) approach that makes a diagnosis of the asset status based on wire or wireless monitored data, predicts the assets abnormality, and executes suitable maintenance actions such as repair and replacement before serious problems happen. In this study, we have addressed several aspects of CBM approach: definition, related international standards, procedure, and techniques with the introduction of some relevant case studies that we have carried out. & 2015 Society of CAD/CAM Engineers.

“…The informational basis for the prognosis of future failures can also be obtained from statistical data about the equipment. However, actual condition information yields more accurate prognoses [15]. The global objective of maintenance depend on a mandatory collaboration (inter and intracompany processes integration), mandatory synchronization of knowledge between all the objects-actors-systems involved in the maintenance process all along the various phases of the product life cycle (human and/or automated actors) [1].…”
Section: Activities For Condition Based Maintenancementioning
Technological development resulted in increased complexity in both industrial machinery and production systems. The modern industry is increasingly demanded to work at high reliability, low environmental risks, and increased human safety while operating their processes at maximum yield. Therefore, prevention of failures and early detection of incipient machine and systems problems increases the useful operating life of equipment. The paper describes a concept of intelligent emaintenance decision making system with effective utilization of expert system capability to condition based maintenance policy. The described system's concept incorporates actual condition monitoring information and modeling modules together with knowledge management module and via health assessment module the most appropriate decision making is realized. The intelligent strategy selection is numerically illustrated.
“…The motivation for this discussion is the implementation of a framework for predictive maintenance as presented in [3]. The aim here is to integrate field devices into the framework with the fewest possible manual configuration effort.…”
With semantic web technologies being in the focus of manufacturing systems designers in recent years, different possibilities to facilitate plant processes have been analyzed. This paper takes a look on existing approaches and compares these with the demands that are given when dealing with automated information integration between different layers of the factory architecture and different phases of the equipment Lifecycle.In order to integrate information, the approach of semantically connecting different communication standards is considered. As a conceptual tool to fulfill the demands given, the use of ontologies, especially the Web Ontology Language OWL, is proposed. Finally, an idea for meeting the difficulties with heterogeneous shop floor ontologies is motivated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
