This predictive maintenance project focuses on
the techniques used to predict when an in-service machine will fail, so that
maintenance can be planned in advance. In particular, this project illustrates
the process of predicting future failure events in the scenario of aircraft
engine failures.
To learn the potential failure of
in-service machine is important in industries to prevent loss. As the data
tracking the performance of machine is available, it is natural to think of
using machine learning to predict the future failure so the maintenance can be
planned in advance.
This projects uses the example of simulated aircraft engine
run-to-failure events to demonstrate the predictive maintenance modeling
process. The implicit assumption of modeling data is that the asset of interest
has a progressing degradation pattern, which is reflected in the asset's sensor
measurements. By examining the asset's sensor values over time, the machine
learning algorithm can learn the relationship between the sensor values and
changes in sensor values to the historical failures in order to predict failures
in the future.
From this project, two modeling
solutions are going to be built
-- Regression: Predict the Remaining Useful
Life (RUL), or Time to Failure (TTF).
-- Binary classification: Predict if an asset
will fail within certain time frame (e.g. days).
