Preventive vs Predictive Maintenance


In regards to maintenance, many times the phrases "preventive" or "predictive" will show up. Both are types of proactive maintenance many field service organizations will engage in to keep their or their customers' products operational without or with minimum downtime.  

Preventive Maintenance

Preventive maintenance is regularly performed on equipment while is still working. It is designed to preserve and restore equipment reliability by replacing worn components before they actually fail. Simple applications of tools to complex replacements can be considered preventive maintenance. 

Predictive Maintenance

Predictive maintenance techniques are designed to help determine the condition of in-service equipment in order to predict when maintenance should be performed. This approach promises cost savings over routine or time-based preventive maintenance, because tasks are performed only when necessary. There are many types of predictive maintenance based on the scale and scope of the project.

Related to this is predictive analytics. Predictive analytics is used to make predictions about unknown future events.It uses many techniques from data mining, statistics, modeling, machine learning, and artificial intelligence to analyze current data to make predictions about future.
