Abstract: A process analysis system includes sensors and a processing system. The sensors monitor the process to generate sensor signals. The processing system processes the sensor signals to detect a deviation from a baseline for the process. The processing system generates a process vector for the deviation in response to detecting the deviation. The processing system compares the process vector to a plurality of library vectors to classify the deviation. In some examples, the process comprises a system that supplies water.
