Transcript of What is predictive maintenance?
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.
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.
Predictive (PM): replace the 10 lightbulbs that will actually break.
But how to find those 10?
Preventive: replace all 1000 lightbulbs.
MAINTENANCE
One hope from Big Data:
Massive amounts of information will substitute for poor quality.
Not necessarily!
Data science will find the 10 lightbulbs.
Prediction is about having correct information. Place relevant sensors at right places.
find the crack when it is small
PM is a combination of:
Understanding the economics of the industrial process
Discovering the proper sources of information
Creating a predictive model
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
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.
