Predictive maintenance uses sensors and data analytics to predict failures in machines before they occur. It aims to replace parts that will break imminently, rather than all parts preventatively. This approach reduces costs compared to traditional preventative maintenance. Developing an effective predictive maintenance program requires understanding machine operations and economics, identifying relevant data sources, and creating predictive models. It is a collaborative process without single solutions, as each machine system presents unique challenges. The goal is finding the optimal balance of predictive efforts and resulting cost savings.
12. One hope from Big
Data:
Massive amounts of
information will
substitute for poor
quality.
Not necessarily!
Data science will find
the 10 lightbulbs.
17. PM is a combination of:
Understanding the economics of the
industrial process
Discovering the proper sources of information
Creating a predictive model
18. Economics:
costs increase with PM effort;
number of sensors,
quality of prediction, etc.
as a result
savings and
profits rise,
but not linearly
sweet spot
PM costs are low,
savings are large
PM can be more expansive than savings
