Improved identification of a process anomaly in a technical facility includes training a self-organizing map using the historical process data as good states of the facility. The good states are used to determine a temporal sequence or a path of node hits and the tolerances of neuron hits. Threshold values are determined and stored for a Euclidean distance for the good states. The Euclidean distance of a current state vector to the neuron hit is checked as to whether the threshold value has been exceeded. The path determined is used to determine the neuron to be hit as long as the threshold value was not already exceeded in the check on the relevant neuron. A symptom vector from the current state vector and either the neuron hit or the neuron that is to be hit is determined.

The invention relates to a position-finding method for d4eterming the location of a mobile object. The features, for example received field strengths, of a plurality of base stations are measured, and the object position is located from these features, using a reference map. During an initialization process, a reference map is created which comprises a multiplicity of positions and the associated feature-dependent values. During use of the method, a plurality of position-finding processes are carried out, by means of each of which a measured feature-dependent value and from this, a located position of the object, are determined using the predetermined reference map. The predetermined reference map is in each case updated for at least some of the positions found, during which updates, the feature-dependent values are each corrected by a correction term at the support points of the reference map in a predetermined area surrounding an object position.
