| Abstract: |
A system and method for predicting web breaks in a paper machine. Principal components analysis (PCA) and classification and regression tree (CART) modeling are used to predict web break sensitivity from sensor measurements taken from the paper machine. Also, the CART model is used to isolate the root cause of the predicted web break sensitivity.

What is claimed is:
1. A system for predicting a web break in a paper machine, comprising:
- a plurality of sensors for obtaining a plurality of measurements from the paper machine, each of the plurality of measurements relating to a predetermined paper machine variable;
- a processor for processing each of the plurality of measurements into break sensitivity data; and
- a break predictor responsive to the processor for predicting a web break sensitivity within the paper machine from the plurality of processed measurements.
