Abstract:
1. A system for analyzing an anomalous condition, comprising: a process for producing a product, including: a parameter extractor for, for each of the subprocesses, receiving the output from the at least one sensor, and for generating at least one representative value that is characteristic of a pattern expressed in the output, the parameter extractor thus generating a plurality of representative values for the process as a whole; a knowledge base for scoring data including a plurality of representative values, and also including information which maps the representative values to associated anomalous conditions; an analyzer for analyzing the plurality of representative values output from the parameter extractor with respect to the data stored in the knowledge base, and for generating a diagnostic result which diagnosis an anomalous condition in the process, and also identifies the subprocesses which has caused the anomalous condition; and control logic for using the diagnostic result to affect corrective action to the at least one subprocess which has caused the anomalous condition by adjusting at least one actuator that controls the at least one subprocess.
