Definitions
- the invention relates to a method for the adaptive control of complex production chains, and to a system for performing such a method.
- a production chain is the series connection of several production machines. So-called buffers are located between the machines, with which different processing speeds of the production machines and short downtimes can be compensated.
- the essential parameter of a buffer is the buffer time, i.e. a time during which a supply of intermediate products is generated, with which a machine downtime can be bridged without the production line coming to a standstill.
- a target buffer time set according to such specifications does not necessarily have to be the optimal buffer time, particularly with regard to the production costs, which are very significantly influenced by production downtimes.
- the optimal buffer time compensates for malfunctions in the preceding machine, so that there is no loss of production.
- Optimal buffer times cannot be achieved with fixed times because influences such as machine age or the quality of the processed material are not taken into account.
- the invention is therefore based on the object of specifying a system and a method for adaptively controlling a production chain by automated optimization of the target buffer times of production chains.
- This object is achieved by a method for controlling a discrete manufacturing process, which has the features specified in claim 1.
- a corresponding system is specified in claim 2.
- Fig. 1 shows schematically the structure of a manufacturing chain.
- the manufacturing process in Fig. 1 is unidirectional and begins with machine M1.
- Buffers P1 to P3 for storing intermediate products are set up between machines M1 to M4.
- the decisive parameter of a buffer is the buffer time Tp, which can be bridged by processing an intermediate product supply when the machine is at a standstill.
- a parameter MTTR (Mean Time to Repair) is assigned to each machine. This measure indicates a statistically averaged repair time.
- FIG. 2 shows a system for the automated determination of optimal buffer times T P j, which are stored as target values in a target value memory 33 of a programmable logic controller (PLC).
- PLC programmable logic controller
- a data processing device contains a production data acquisition device 21 which has access to a data server 30, in which Production data are recorded, and 11 additional error event data can be entered by means of a data input.
- the production data acquisition device 21 is set up to record machine downtimes and to store them in a production database 31 as time series.
- An MTTR calculator 22 has access to the production database 31 and stores calculated MTTR key figures in an MTTR database 32.
- a Tp calculator 23 also contained in the data processing device has access to the MTTR database 32 and sets buffer times T calculated by it Pi in the setpoint memory 33.
- Fig. 3 shows the operation of the system shown in Fig. 2.
- the downtimes of the machines required for the optimization including error event information, are recorded by means of the production data acquisition device 21 and stored in the production database 31 as time series.
- the MTTR calculator 22 calculates the MTTR key figures. The MTTR results from the duration of the downtimes in the life cycle of a machine. The information is in the production database 31. If an error event occurs, the MTTR is recalculated.
- step 300 the MTTR is stored in the MTTR database 32.
- the current MTTR key figure is saved for each machine. It is also possible to additionally store the changes in the MTTR during the entire operating period in the MTTR database 32 for later analysis.
- step 400 it is observed whether the MTTR changes significantly over time. Significance is recognized (MTTR alarm) when a specified delta threshold value is exceeded.
- the respective new buffer time T P j is calculated by the Tp calculator 23 and specified as the target value in the target value memory 31.
- Different assessment models can be used to determine the optimal buffer time. If, for example, the production costs are only influenced by the standstill of the production chain, the buffer times are chosen so that the machine downtimes are compensated. This means that the optimal buffer time results directly from the MTTR of the machine before the respective buffer.
- FIG. 5 shows an example of an evaluation model that additionally takes into account the costs due to the buffer.
- the fault event data can either be derived automatically by the production data acquisition 21 or the machine operator enters the data via the data input 11.
- the evaluation is based on the unit cost of the product.
- the production unit costs are influenced by machine costs, buffer costs and the product quantity n.
- the buffer costs increase with a constant buffer cost factor Kp with the buffer time Tp.
