Systems and methods for automated workflow comprise assigning a set of first targets to an uncompiled first workflow. The uncompiled first workflow specifies a first set of process modules. Each such module is associated with a subset of unit operations. Each unit operation includes a time interval and specifies an instrument. For each target in the set of first targets, the uncompiled workflow is translated into an instance of a compiled first workflow comprising a linear temporal order of unit operations, each including execution instructions for an addressed instrument. A set of second targets is obtained and assigned a second uncompiled workflow. Compilation of the second uncompiled workflow for each second target produces a different instance of a compiled second workflow. Each second compiled workflow comprises a linear temporal order of unit operations, with each unit operation including execution instructions for an addressed instrument and specifying a time interval.

This makes it easier to maintain the accuracy of the automatic control of the device. [Solution] In the calibration device 10, the calculation unit 15b calculates a calibration value for the control value based on the deviation between the measured value and the target value of the evaluation target in the device being processed, which is controlled by the control value. The addition unit 15c adds the calculated calibration value to the recommended value of the control value output by the model 14a, which has been learned by imitation learning.

The invention relates to a method for determining control values ​​of a manipulated variable for a pressure medium supply system of a hydraulic system with at least one hydraulic consumer (10), wherein the pressure medium supply system comprises a hydraulic machine (2) and an electric drive (4, 6) coupled thereto and is controlled by the manipulated variable, wherein an inverse plant model (47) is given for the hydraulic system, which uses values ​​of a state variable to be controlled of the hydraulic system and of time derivatives of the state variable up to a predetermined maximum order as input values ​​and maps these to an output value for the manipulated variable; comprising determining (110) trajectory values ​​(36) of a trajectory for the time course of the state variable and derivative values ​​(38, 40) for time derivatives of the course of the state variable up to the maximum order from predetermined setpoint values ​​(32) for the state variable;Determining (120) compensation values ​​(73) with a compensation controller (75) from a control deviation (61) between the trajectory values ​​(36) and actual values ​​(54) of the state variable; and determining (130) manipulated values ​​(50) for the manipulated variable using the inverse plant model (47) from the trajectory values ​​(36), the derivative values ​​(38, 40) and the compensation values ​​(73).

To automatically generate a process model in which a flow shop and a job shop are mixed, by automatically determining a production system between processes by using work result data obtained at a manufacturing site.SOLUTION: A process model automatic generation system 210 reads work result data from work result data 120 and extracts a process flow for each product (130). Next, a synthetic flow obtained by adding a plurality of process flows is created, and a production system between processes corresponding to a closed path is changed to a job shop, thereby automatically determining the production system (140). Finally, a process model in which a flow shop and the job shop are mixed is generated (150) and displayed on a display screen 160.SELECTED DRAWING: Figure 1
