The challenges of system health management and failure prognostics
نویسنده
چکیده
For the aim of system health management, equipment and components are inspected periodically by manual or automatic systems to monitor their condition and to identify their level of degradation. A decision is then taken regarding replacement or maintenance, and this is based upon an analysis of the monitored data. In this view maintenance is carried out when a measurable machine condition shows the need for repair or replacement. This strategy aims at identifying problems in equipment at the early stage so that necessary downtime can be scheduled for the most convenient and inexpensive time. This allows a machine to run as long as it is healthy: equipment is only repaired or replaced when needed as opposed to routine disassembly. By so doing, one aims at achieving maximum availability, minimizing unscheduled shutdowns of production, scheduling maintenance actions as economically as possible.
