What is Maintenance Decision Automation?
We automate a decision process because we don’t want to make day-to-day decisions each time from first principles. There aren’t sufficient human resources available in the Maintenance Department to eyeball every graph of condition monitoring data and every work order comprising an item’s maintenance and failure history. Yet these databases are generally believed to hold…

EXAKT needs LRCM
The most important practical issue from our experience is that EXAKT cannot give satisfactory service to a typical maintenance department without the LRCM process implemented. The reason for this is that EXAKT is extremely sensitive to the accuracy of discrimination of Event Type and to the consistency of Failure Mode selection both of which are…

Measuring and Improving CBM Effectiveness
Maintenance departments regularly implement policies and technology aimed at improving maintenance effectiveness. However engineers who implement and justify such projects in the maintenance department often encounter difficulty when trying to quantify, credibly, a project’s impact on maintenance or on asset performance. The problem lies in the many factors governing Performance Metrics at different time periods. How…

A survey of signal processing and decision technologies for CBM
Introduction Condition-based Maintenance recommends actions based on information acquired through observation and analysis. We note, moreover, that the CBM process, itself contains three sub-processes or steps: data acquisiton, signal processing, and maintenance decision making.

Temporary fix work orders
In a fleet of 40 haul trucks, a common work order type is triggered by a low level alarm of some fluid (for example, hydraulic, coolant, lubricant, air, etc). Sometimes some function will not perform adequately or at all due to insufficient fluid. The immediate quick fix will replenish the fluid and put the unit…
