Prognostics is the science of forecasting when your assets will stop being able to perform their intended functions. It means that you can properly perform predictive maintenance, with the right information and it is undoubtedly the future of condition monitoring.
It’s our job to crunch the numbers and to do the maths (or magic!), the output for you and the key reason why prognostics is so exciting is that you get to know the Remaining Useful Life of your machines.
How it’s done
Prognostics is achieved by understanding the signatures and characteristics of past failures and mapping those to current machine behaviours. The behaviour of machines is recorded from various sensor inputs (ideally using data that you already collect for historical analysis). The ability to capture this information is one of the key reasons that Industry 4.0 (aka the Industrial Internet of Things or Smart Factories) is so exciting.
As in the above diagram, machines operate within a ‘normal band of operation’. When sensor readings start to deviate from normal, this can be an early indication of failure and can be detected as an anomaly. Prognostics calculations work out the trajectories of those anomalies in order to calculate when they will lead to functional failure of the machine being monitored. This can be used to give a Remaining Useful Life of the asset or machine and is why prognostics is so essential for predictive maintenance.
How it’s used
Prognostics can be used on any machinery although it’s best when looking at collections of assets that have strong commonality. It’s a technique that can be used by very good data scientists but we know that to use it at scale, it’s a task best left to large computers, able to run a number of algorithms simultaneously and use Machine Learning to understand which are performing the best.
