Definitions
- the invention relates to a system and a method for controlling orders of a manufacturing device.
- Such a system is used, for example, in the field of automation technology in order to achieve the best possible throughput of a manufacturing device or an entire manufacturing system from several manufacturing devices.
- the problem frequently arises here of managing a number of orders, which are also referred to below as jobs, in the production device or the production system in such a way that the resources available, i.e. the available individual modules of the production device or the production system can be used as efficiently as possible and at the same time the shortest possible duration of the orders and jobs can be achieved.
- job shop scheduling This problem of optimal utilization is also referred to as “job shop scheduling.
- a device and a method for generating adaptive workflows is known. With the help of a scheduler and an assigned workflow rule, individual order sequences are dynamically adapted to a changing work environment. If a control device detects deviations, the work processes of unfinished orders can be put together again. Monitoring means are provided which contain a virtual image of the physical environment.
- the invention has for its object to provide a system and a method that an analysis of the current situation, a planning of the necessary operations, as well as the execution and monitoring of the same in particular also dependent on mathematical routines to optimize throughput.
- This task is solved by a system for controlling orders of a production device with a data processing device, the planning means for determining a possible optimal order of the orders based on a starting situation with regard to existing resources and existing orders with the aid of an optimization algorithm and sequence control means for coordinating the Control of the manufacturing device with the aid of a solution algorithm, which is provided for determining a target state by simulating the necessary operations of the manufacturing device.
- This object is further achieved by a method for controlling orders of a production device, in which, starting from an initial situation based on real resources and real orders, a simulated image is formed, in which a possible optimal order of the orders based on the initial situation with respect to available resources and existing orders are formed with the aid of an optimization algorithm and in which the production device is controlled with the aid of a solution algorithm such that a target state is determined by simulating the necessary operations of the production device.
- the invention is based on the finding that manufacturing devices or manufacturing systems are often subjected to serious changes in a relatively short time. For this reason, in the present method, a simulated image of reality is first generated based on the initial situation, which is based on the real resources and the real orders. Based on this initial situation, a possible optimal order of the orders is formed in the following step with the help of an optimization algorithm. The sequence of orders in the form of sequences determined in this way is then verified by the solution algorithm, which attempts to achieve a predefinable target state by simulating the necessary operations of the production device. The resulting modularity of the solution results in a generic solution for scheduling tasks, which can also be easily adapted to changes in the production device or the production system.
- a simulated image of a real situation can be generated in a simple manner by the system having first means for generating an image of the initial state of the production device with respect to available resources and existing orders.
- the production device is a production machine, a production machine, a production system and / or a production system.
- a further improvement of the order control is achieved in that the solution algorithm for verifying the possible optimal order of the orders determined by the planning means is provided. Efficient processing of jobs that are already waiting is achieved in that the planning means for coordinating the start of waiting jobs is provided on the basis of the current situation image, in particular with the aid of the optimization algorithm.
- a further optimization of the planning tasks and the temporal control of the order sequences can take place in that the step in which a possible optimal order of the orders is formed on the basis of the initial situation with regard to existing resources and existing orders with the aid of the optimization algorithm.
- Desired target states relating to the production device that can be specified automatically or by the user can be taken into account in that the solution algorithm tries, based on a given simulated situation, to achieve a predefinable target state of the production device by simulating the necessary operations / steps.
- a clear and targeted presentation of results can be ensured by the fact that a list of actions, which includes all actions until the system is finally emptied, is used to determine operations and reactions in advance.
- Faulty situations can be easily identified by continuously evaluating the situation and creating new actions for the elimination / avoidance of problem cases.
- Show it: 1 shows a schematic representation of a system for
- FIG. 2 shows a schematic representation of a system for
- FIG. 1 shows a schematic representation of a system 9 for order control of a production device 3.
- the production device 3 in the exemplary embodiment shown in FIG. 1 is characterized by resources R1..R3 and currently existing orders J1 .. J3.
- the system 9 for order control of the manufacturing device 3 further comprises a data processing device 4, which forms a simulated image 6 of the real manufacturing device 11.
- the simulated image 6 of the production device 3 comprises simulated resources SR1..SR3 as well as simulated orders or simulated jobs SJ1, SJ2, SJ3.
- the schematic principle of the job control which is present on the data processing device 4, further comprises a planning device 16 and a sequence control 17, the planning device 16 also being referred to below as a scheduler 16 and the sequence control 17 also referred to below as a dispatcher 17.
- the planning device 16 coordinates the starting of the waiting jobs SJ1..SJ3 or J1..J3 on the basis of a current situation 18 with the aid of an optimization algorithm 12.
- the sequence control 17 coordinates the necessary actions for the safe control of the system 3. For this purpose, it uses a solution algorithm 13 who creates an action list 14 from the result, which is also managed by the sequence controller 17.
- the action list 14 contains a list of actions A1, A2 .. to be carried out for the processing and coordination of the jobs Jl .. J3.
- the basic function of the job control of the system shown in FIG. 1 is explained in more detail below: Starting from the current situation of the real manufacturing device 3, consisting of the real resources Rx and the real jobs Jx, a simulated image 6, characterized by the simulated resources SRx and the simulated jobs SJx, which provides the necessary information as current situation 20 for the job control.
- the units on the data processing device 4, namely the planning device 16 and the sequence control 17, are two independently operating units, the planning device 16 being responsible for the planning of the new orders, ie for their starting time and their starting sequence.
- the sequence control 17 takes over the processing, the distribution and the forwarding of the orders. If required, both units, the planning device 16 and the sequence control 17 each require current situation images 18, 19, which are derived from the simulated situation 20 as an image of the real situation.
- the planning device 16 first uses the current situation 18 to determine a possible optimal job sequence, in accordance with the optimization algorithm 12. This sequence is transferred together with the current situation 18 to the solution algorithm 13 so that the plausibility of the proposed solution can be checked. According to the optimization algorithm 12, the step for determining a job sequence or the plausibility of the determined sequence can take place several times.
- the optimal result determined in each case is forwarded from the planning unit 16 to the sequence controller 17 via a transfer unit 15 with transfer places ÜPL, ÜPx to the sequence controller 17.
- the sequence controller 17 also requests the current situation 19 of the production device 3 or the system, if necessary, and uses the solution algorithm 13 to calculate a list of the actions A1, A2 ... to be carried out.
- the solution algorithm 13 thus uses its simulation rules to calculate all the actions AI..An at a predefinable target state, for example until the production device 3 is completely "empty", which is, for example, a semiconductor production device. Due to the modular construction with planning means 16 and sequence control 17 as well as optimization algorithm 12 and solution algorithm 13, the solution algorithm 13 is the only part of the system which has to be specifically adapted to the respective production or to the respective system.
- the solution algorithm 13 recognizes that a situation arises during the simulation and when the action list 14 is created, which can no longer be solved, then in this case the solution algorithm 13 can determine in advance at what time problems in the Plant or in the manufacturing device will occur. A user can therefore take countermeasures in advance and thus prevent system malfunctions that otherwise occur.
- the actions Al..Ax of the action list 14 contain the reactions which are to be triggered by a control of the production facility or the system, so that correct processing of the jobs J1..J3 is ensured.
- These actions AL.Ax are created with a start time and the corresponding dependencies on the basis of the simulation rules of the solution algorithm 13, if necessary, when called up by means of the sequence control 17.
- the actions AL.Ax are started at the computing time, checking their dependencies. Such a check of the dependencies, for example in the case of a semiconductor manufacturing device, means that a so-called dealer located there can only place in a specific module if a cover, for example on the module, has previously been opened. If the review all dependencies were successful, the actual action is triggered first.
- the automation system 10 comprises a programmable logic controller 2, an operating and monitoring system 1 and a data processing device 4 on which an order control program 9 can run.
- the job control program 9 comprises a simulated image 6 of the real manufacturing device 3, an algorithm 8 and a user interface 7.
- the user interface 7 is connected to a data link 5, for example an OPC (Open Process Control) with the operating and monitoring system 1 and via this with the programmable logic controller 2 and this in turn with the manufacturing device 3 in connection.
- the manufacturing device is in particular a semiconductor manufacturing device, for example a so-called wetbench.
- the production device 3 is characterized by pending orders JL.Jn and existing modules (resources) Rl..Rn and by a handling device R0 as a further resource.
- the individual orders JL.Jn should be controlled and managed in such a way that an optimal throughput of the production device 3 can be achieved.
- the orders JL.Jn are to be managed and controlled in the production device 3 in such a way that the individual resources R0..Rn can be used as efficiently as possible, and at the same time the shortest possible runtime of the jobs JL.Jn can be expected.
- the individual jobs JL.Jn can consist of various sub-steps, so-called tasks T1..T13, T21..T23, each of which
- Step by a conversion operation of resource RL .Rn Step by a conversion operation of resource RL .Rn.
- the jobs JL.Jn can thus have a different number of steps and sequences.
- This problem of optimum utilization is solved with the help of the job shop scheduling program 9 which can run on the data processing device 4 using the procedure explained in connection with FIG.
- the invention thus relates to a system 9 and a method for controlling orders Jl .. Jn in a manufacturing device 3.
- a planning of the necessary operations, as well as their execution and monitoring independent of mathematical routines for optimizing the throughput starting from a starting situation 11 based on real resources RL .R3 and real orders J1..J3, a simulated image SR1..SR3, SJ1..SJ3, with the help of an optimization algorithm 12, a possible sequence 15 of the orders JL.Jn is optimized based on the initial situation 11 with respect to existing resources Rl..Rn and existing orders JL.Jn and the production device 3 is controlled with the aid of a solution algorithm 13 in such a way that a target state 14 is determined by simulating the necessary operations of the manufacturing device 3.
