Equipment maintenance is one of the essential tasks for manufacturing industries. There have been a number of information systems developed to cope with equipment malfunctions. Most fault diagnosis systems are applications of expert systems which have two drawbacks with regard to knowledge acquisition. One is the lack of knowledge continuity; the other is the limited source of knowledge being i...

In view of the very complex equipment making up the LHC machine and its many ancillary subsystems, equipment maintenance policies will play a primordial role to ensure an optimal availability. As access to most of the machine systems is strictly regulated, maintenance interventions will require global co-ordination and collaboration from both CERN equipment groups and industrial support teams. ...

Hospitals outsource several activities of the service support in order to focus on the core healthcare production as maintenance service. Recently, faced to the sophistication and the costs of medical equipment that continue to escalate, governments have implemented new reforms to control costs and improve the efficiency and the quality. Hospitals become interested in minimizing the total opera...

Improving the use of power plant information sources for equipment fault diagnosis will help electric utilities meet plant availability goals and reduce operations and maintenance costs. The combination of data from multiple information sources--such as data historians, predictive maintenance technologies, and operator rounds-can provide a holistic view of condition for a given item of equipmen...

This paper makes a link between opportunistic maintenance literature and warranty analysis of a power plant. A new plant warranty maintenance tasks are observed over a two year period. The main aim is to see how opportunistic maintenance could be incorporated when the warranty period has elapsed. The paper examine the warranty period maintenance task list and propose adequate methods for assess...

The unexpected failures, the down time associated with such failures, the loss of production and, the higher maintenance costs are major problems in any power plant. Riskbased maintenance (RBM) approach helps in designing an alternative strategy to minimize the risk resulting from breakdowns or failures. The RBM methodology is comprised of four modules: viz identification of the scope, risk ass...
