Fluid flow analysis and management

A system and method for observing fluid flow behavior at a selected site, deriving judgments and recommendations, and further communicating data, judgments and recommendations. The system receives flow rate information, derives a time series of fluid flow events therefrom, identifies compound events consisting of contemporaneous events, disaggregates compound events by application of an unsupervised model, and applies the unsupervised model to derive a solution space of a subset sum problem-type, wherein historical data of the observed fluid flow is not necessarily accessed. The system derives a prior probability of events associated with an event conditional upon event features and attributes, and thereupon estimates prior probabilities based upon user-derived labels for events from many external sites; and/or derives a posterior probability of labels associated events, conditional upon event features and attributes, and estimates posterior probabilities based upon both prior updated information relating to the selected site and a priori calculated probabilities.
