What is Predictive Maintenance?

Production depends on machines, and they need to work well.

When a machine breaks, this costs time, money,

…lives.

That is why we preventively maintain them.Better to fix one hundred parts that could break than to have one of them broken at a critical time.
![Page 6: What is Predictive Maintenance?](https://reader031.vdocument.in/reader031/viewer/2022030305/58719b2b1a28ab044e8b5ad7/html5/thumbnails/6.jpg)
In a perfect world, we could predict which part will break and exactly when.
![Page 7: What is Predictive Maintenance?](https://reader031.vdocument.in/reader031/viewer/2022030305/58719b2b1a28ab044e8b5ad7/html5/thumbnails/7.jpg)
But in most cases prediction is only stochastic.
Out of 1000 items, we know about 10 will break.However, we don’t know which ones.
![Page 8: What is Predictive Maintenance?](https://reader031.vdocument.in/reader031/viewer/2022030305/58719b2b1a28ab044e8b5ad7/html5/thumbnails/8.jpg)
Predictive (PM): replace the 10 lightbulbs that will actually break.
But how to find those 10?
Preventive: replace all 1000 lightbulbs.

Traditional predictive maintenance using the most versatilesensor in the world: human eye

…and human ear: vibration analysis

Today: Sensors + Big Data + Analytics
![Page 12: What is Predictive Maintenance?](https://reader031.vdocument.in/reader031/viewer/2022030305/58719b2b1a28ab044e8b5ad7/html5/thumbnails/12.jpg)
One hope from Big Data:
Massive amounts of information will substitute for poor quality.
Not necessarily!
Data science will find
the 10 lightbulbs.
![Page 13: What is Predictive Maintenance?](https://reader031.vdocument.in/reader031/viewer/2022030305/58719b2b1a28ab044e8b5ad7/html5/thumbnails/13.jpg)
Can’t get something
out of nothing
This is what data science is not.
![Page 14: What is Predictive Maintenance?](https://reader031.vdocument.in/reader031/viewer/2022030305/58719b2b1a28ab044e8b5ad7/html5/thumbnails/14.jpg)
Prediction is about having correct information. Place relevant sensors at right places.
find the crack when it is small
![Page 15: What is Predictive Maintenance?](https://reader031.vdocument.in/reader031/viewer/2022030305/58719b2b1a28ab044e8b5ad7/html5/thumbnails/15.jpg)
Each PM problem is unique.
There is no one-approach-fits-all in PM.
![Page 16: What is Predictive Maintenance?](https://reader031.vdocument.in/reader031/viewer/2022030305/58719b2b1a28ab044e8b5ad7/html5/thumbnails/16.jpg)
But PM is not only about predicting.
![Page 17: What is Predictive Maintenance?](https://reader031.vdocument.in/reader031/viewer/2022030305/58719b2b1a28ab044e8b5ad7/html5/thumbnails/17.jpg)
PM is a combination of:
Understanding the economics of the industrial process
Discovering the proper sources of information
Creating a predictive model
![Page 18: What is Predictive Maintenance?](https://reader031.vdocument.in/reader031/viewer/2022030305/58719b2b1a28ab044e8b5ad7/html5/thumbnails/18.jpg)
Economics:costs increase with PM effort; number of sensors, quality of prediction, etc.
as a resultsavings and profits rise, but not linearly
sweet spotPM costs are low, savings are large
PM can be more expansive than savings

Reserve time for experimenting.You will encounter failures before success.
![Page 21: What is Predictive Maintenance?](https://reader031.vdocument.in/reader031/viewer/2022030305/58719b2b1a28ab044e8b5ad7/html5/thumbnails/21.jpg)
Finally, a data scientist can create a model. Remember: machine learning is a tool, not a solution.

Putting all aspects of PM together is a collaborative work.

in conclusion
![Page 24: What is Predictive Maintenance?](https://reader031.vdocument.in/reader031/viewer/2022030305/58719b2b1a28ab044e8b5ad7/html5/thumbnails/24.jpg)
Predictive Maintenance is as much research as it is data handling.
It is rather a process and a mindset.
It has no single best practice.
