Conditioned-based maintenance CBM

Maintenance is not merely called upon to repair failed equipment (breakdown maintenance). Over the course of time, maintenance workers have teamed with plant operations personnel to develop preventive maintenance (PM), predictive maintenance (PdM), and condition-based maintenance (CBM) programs, all in an effort to get ahead of problems occurring in plant operations, and to do so as efficiently as possible. 

One of the most advanced maintenance strategies that can be implemented is the Condition Based Maintenance (CBM). It is a very powerful approach but requires several technology devices as sensors, acquisition card, etc. and relevant knowledge in order to implement the diagnostic and prognostic intelligence. 

In this way, according to Jardine et al. (2006) more efficient maintenance approaches such as condition-based maintenance (CBM) may be implemented to handle this simation. CBM is a maintenance program that recommends maintenance actions based on the information collected through condition monitoring (OMS, for instance). CBM attempts to avoid systems being over or imder maintained by taking maintenance actions only when there is evidence of abnormal behaviors of a physical asset. 

Finally, with regard to condition based maintenance (CBM) of engineering systems it is important to detect the initiation of incipient faults, to assess the current health of a system and to predict the remaining useful life (RUL) of a component that has become faulty. As bond graph modelling enables the systematic generation of ARRs for FDI, it can also support failure prognosis. 

Structural health monitoring (SHM), condition-based maintenance (CBM) and birth-to-retirement refer to the capability of using sensors throughout the life or an adaptronic structure to monitor its state of health and act ac-... 

One important development in this area has been that of condition-based maintenance (CBM). The objective of CBM is to use non-invasive techniques to detect the current state of systems both to decide whether or not intervention is needed and accurately to predict their remaining useful lives. This enables engineers to perform maintenance only when needed to prevent operational deficiencies or failures, essentially eliminating costly periodic preventive maintenance and reducing the likelihood of plant failures.
