What is Predictive Maintenance?

Predictive maintenance (PdM) techniques are designed to help determine the condition of in-service equipment in order to predict when maintenance should be performed.

More Detailed Information

What questions can be answered from Predictive Maintenance?



What is the probability that a piece of equipment fails in the near future?



What is the remaining useful life of the equipment (RUL)?



What are the causes of failures and what maintenance actions should be performed to fix these issues?


Why Predictive Maintenance?

Utilizing machine learning through regression and classification algorithms, Predictive Maintenance can analyze patterns and determine the remaining useful life of any equipment. An Apriori algorithm is used to recommend whether a particular equipment will be needing maintenance alongside other equipment based on historical maintenance data.

According to a study by the Department of Energy (US), a facility that leans heavily on predictive (rather than reactive or preventative) performance management methods can save 30-40% in equipment maintenance costs.

Reduced equipment costs

Instead of replacement of the entire piece of equipment due to critical failure, a repair is made prior to failure and cost is minimized to the price of the component and the labor needed for the repair.



When repairs are scheduled, the amount of time needed for repair is reduced because of a smaller number of component replacements instead of entire equipment replacement. Also, the frequency of repair for critical failure of equipment will be reduced and the amount of “critical callouts” will be greatly reduced..


Increased Safety

Predictive maintenance would allow potential problems to be fied before failure occurs, which would create safer operating conditions for employees and customers..

Reduces lost production time

Component only replacement is scheduled with production to take place during scheduled downtime. Unscheduled downtime may cost thousands of dollars per hour. A proactive maintenance department can head of critical failure downtime by scheduling repair during non-productive times.
