Assignee: BENTLEY SYSTEMS, INCORPORATED
Field: Control (Instruments)
Classification: CPC G | IPC G

Claim 11:
12. A non-transitory electronic device readable medium having instructions stored thereon that when executed on one or more processors of one or more electronic devices are operable to:
receive time series data that includes both flow and pressure measurements at a plurality of time steps from one or more sensors of a water distribution system;
detect, using a statistical process control (SPC) algorithm, outliers of the time series data;
classify sensor events in response to flow or pressure of detected outliers exceeding high or low thresholds for at least a given number of time steps;
classify anomaly events by correlating one or more sensor events related to flow with one or more sensor events related to pressure;
determine a quantitative score for each of the detected anomaly events that indicates a level of significance or importance based on a density of sensor events for the anomaly event and a spread of the sensor events for the anomaly event; and
provide at least the detected anomaly events and their respective quantitative scores.
