Abstract:
1. A method for computer-assisted evaluation of characteristic values of a technical system, comprising: dividing a total temporal interval into a plurality of partial intervals, the total temporal interval having a start point and an end point between which a plurality of characteristic values of the technical system are determined, each partial interval occurring between a partial interval start point and a partial interval end point within the total temporal interval, each partial interval having at least one characteristic value determined therein; adapting, for each partial interval, one or more parameters of a predetermined predictive model, the parameters being adapted to the at least one characteristic value determined in the partial interval, the parameters being adapted to provide partial adaptations, each partial adaptation having a corresponding partial interval and a corresponding partial interval end point; allocating the adjacent partial intervals with respective adjacent partial adaptations, the partial interval end point of each partial interval being adjacent to the partial interval end point of the respective partial adaptation; determining a modification measure for each of the partial adaptations specifying the modification of the parameters of a respective partial adaptation with reference to the parameters of at least one adjacent partial adaptation; determining if each modification measure is greater than a predefined value; and for each modification measure that is greater than the predefined value, flagging as an inhomogeneous interval the time interval between the partial interval end point of the respective partial adaptation and the partial interval end point of the adjacent partial adaptation.
