Claim One:
1. A method for detecting anomalies in a fluid distribution network, the method comprising: establishing, for the distribution network, a direct model comprising: structural data of the distribution network relative to the topography of said distribution network and comprising setpoints or status data of equipment of said distribution network, operational data relative to parameters chosen as primary input parameters describing an operational scenario, and laws linking said structural data, the primary input parameters, and primary output parameters; executing the direct model by a hydraulic simulation engine to determine theoretical values of the primary output parameters; obtaining measurements from data acquisition systems of the primary output parameters; comparing the theoretical values with the measurements; when the comparing reveals at least one of the primary output parameters that is abnormal because of at least one significant deviation between at least one of the theoretical values and at least one of the measurements, establishing an inverse model comprising a minimization of a function of a deviation between measurement and simulation at a measurement point, relative to a configurable set of parameters, the inverse model being derived from the direct model by introducing the at least one abnormal primary output parameter as a secondary input parameter of the inverse model, the secondary input parameter taking the measurement as a value, the inverse model comprising at least one secondary output parameter in addition to the primary output parameters which are retained; executing the inverse model by the hydraulic simulation engine; and locating an anomaly of the distribution network from the execution of the inverse model.
