| 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 measurements taken from the paper mill. 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 located about a paper mill, comprising:
- a paper mill database containing a plurality of measurements obtained from the paper mill, 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.
