Abstract: A computer-implemented method using a processing unit and including providing to or determining by the processing unit a totality of process variables which is available for processing for the plurality of actuators and/or sensors of a subunit, using the processing unit to determine a subset of process variables out of the totality of process variables processing, during production of a production lot, those process variables which belong to the determined subset of process variables for those process variables which do not belong to any of the determined subset of process variables, and processing a selected number of process variables. In addition, a production cell has a processing unit configured to carry out the computer-implemented method, and computer program is provided to implement such a method.

Abstract: A method for monitoring a molding process carried out in cycles includes determining at least two nearest neighbors in the form of cycle data from at least two past cycles, such that the cycle data of the at least two nearest neighbors lie nearer to the current cycle data than the cycle data which do not pertain to the at least two nearest neighbors. Only those past cycles for which quality data are contained in the data collection are used for the determination of the at least two nearest neighbors. A predictability criterion is checked to determine whether a quality variation of the quality data of the cycles of the at least two nearest neighbors is smaller than a maximum variation and/or larger than a minimum variation. If the predictability criterion is not met, a first notification that a quality and/or a quality datum of the molded part is not reliably predictable is issued.

Abstract: The invention relates to a control circuit (27) for a waste heat recovery system (2) for a heat engine (36). The waste heat recovery system (2) comprises at least one evaporator (21) for converting waste heat from the exhaust gas (31, 31a) generated by the heat engine (36) into a working medium (23), at least one expansion machine (24) which can be driven by the working medium (23), at least one condenser (25) for condensing the working medium (23a) expanded in the expansion machine (24) into the liquid state (23b), and at least one conveying device (26) for increasing the pressure of the condensed working medium (23b) and conveying same into the evaporator (21). The control circuit (27) influences at least one control variable which controls the energy transmission from the exhaust gas (31, 31a) to the working medium (23b) and/or the energy transmission from the working medium (23c) to the expansion machine (24).

Abstract: A target value progression for a process parameter functioning as a setting variable is established so that an actual value progression for a selected variable has a desired property, or the desired actual value progression itself ensues. The actual value progression occurring in relation to the first configuration is predetermined as a reference value progression for the selected variable, and a target value progression for the process parameter functioning as the setting variable is established by a computer so that the reference value progression as the actual value progression with the desired property or the desired actual value progression itself ensues when the shaping machine in the second configuration operates in a production cycle in accordance with the selected target value progression for the at least one process parameter functioning as the setting variable.

Abstract: A device for monitoring a production facility includes a computing unit, at least one sensor, a memory unit, and an output device. In the memory unit, in each of at least one process variable set, at least three possible process states are stored and at least one algorithm is stored by which the one of the different possible process states actually present can be calculated, the possible process states that differ in relation to the respective process variable set are classified according to whether measures are necessary or recommended, the commands by the computing unit prompt it to execute the associated algorithm and thus to calculate which of the different possible process states is actually present and to check whether the actually present process state is classified as such a process state, to generate and output an electronic message depending on the calculated process state.
