To determine a quality indicator of production batch-run of a production process, a computer compares time-series with multi-source data from a reference batch-run and time-series with multi-source data from the production batch-run. Before comparing, the computer converts multi-variate time-series to uni-variate time-series, by first multiplying data values of source-specific uni-variate time-series with source-specific factors from a conversion factor vector and second summing up the multiplied data values according to discrete time points. The source-specific factors of the conversion factor vector are obtained earlier by processing reference data, including the determination of characteristic portions of the time-series, converting, aligning by time-warping and evaluating displacement in time between characteristic portions before alignment and after alignment.

An exemplary control apparatus for an energy distribution system includes a connection to an alternating current supply system and a plurality of predetermined loads each having an energy storage capacity and being electrically connected as by a respective switching device to the alternating current supply system for a duration of a half-wave or a whole number times said half-wave. The respective switching devices are supplied electrical energy from the alternating current supply system for a respective control time period within a predetermined common cycle time period. The start and end of the respective control time periods within the common cycle time period are established prior to the start of said common cycle time period to create a substantially constant loading graph. The optimization procedure is based at least one load in lieu of a continuous control time period having at least two non-continuous block time periods of equal total duration.
