The Asset Management Council has released the next issue in its series of e-books exploring commonly asked Asset Management Questions. This paper addresses the belief that there is no difference between maintenance based on the assessed condition of an item and the maintenance of an item that degrades to the point of functional failure.
Physical plant assets are tending to remain in service for beyond their design lifetime. Arguably, a greater professional input is needed into the maintenance and reliability engineering of these assets, yet few universities offer such content in undergraduate engineering degrees. Accordingly, postgraduate programs have been developed.
A Split System Approach (SSA) based methodology is presented to assist in making optimal Preventive Maintenance decisions for serial production lines. The methodology treats a production line as a complex series system with multiple PM actions over multiple intervals.
Maintenance management is a complex partnership between the people directly or indirectly involved in maintenance, the processes and strategies to direct the people’s actions, the physical assets being maintained, and the Computerised Maintenance Management Systems – the main link between the “people”, the “processes and strategies”, and the “asset”.
Predictive maintenance (or prognostics) is critical to any engineering systems to avoid system breakdown, in particular, for complex systems. With the recent advances on pervasive computing, prognostics can be easily embedded in any devices and systems.
An organization’s maintenance strategy may consist of many thousands, even tens or hundreds of thousands of preventive maintenance activities. These activities, properly executed, determine the success of the preventive maintenance program.
