CBM Optimization
Nature, and therefore humankind, must optimize to survive and prosper. Each species in the animal kingdom strives for the best long term results of its actions. Whether divinely designed or as a result of natural selection, activity is calculated (optimized) to balance low energy expenditure with maximum caloric intake. No less true is a business’s…

Internal and external CBM variables
As maintenance or reliability engineers we need to discover what factors influence failure and failure probability. Which of those factors can we control, and which can we monitor for their predictive content. It will help to distinguish between External and Internal variables. Definition: External CBM variables such as loading, operator discretionary actions, shock, terrain, etc.…

The elusive P-F interval
This article discusses the P-F Interval for CBM decision making, its areas of usefulness, and those areas where it is inadequate as a predictive maintenance strategy. An alternative more general approach based on the EXAKT system is proposed. Two categories of decisions, the first driven by failure probability, the second driven by both failure probability…

CBM Exercises
The exercise included on this page uses EXAKT CBM modeling software. EXAKT is an advanced Living RCM Certified® reliability analysis system that predicts a component’s remaining useful life based on its age and current condition. A maintenance department achieves continuous equipment reliability improvement by capturing and then analyzing accurate history data. The videos illustrate the…
