Definitions
- the invention relates to a method for planning, implementing, monitoring and optimizing process sequences, in which a large number of different process data are stored in at least one first database.
- the invention further relates to the use of a method according to the invention in motor vehicle production.
- the problem with the known process planning is, on the one hand, that the overview of these is lost due to the large amount of data collected. It can no longer be guaranteed that an optimal combination of individual process steps will be found.
- the different designs in the individual production facilities result in different quality standards; improvements that are found are not available to other production facilities.
- the total effort for an implementation increases significantly, since every characteristic has to be redesigned in every production facility and it is not possible to provide an experience-optimized method through knowledge transfer to a large number of production facilities.
- the object of the invention is therefore to provide an efficient and cost-effective method for the planning of process sequences.
- the object shown above and known from the prior art is achieved according to the invention by a method in which stored process data are called up via a data network and at least one workstation computer, in which stored process data can be combined with one another and made comparable with the aid of the workstation computer, in which a comparison of the process data, individual processes are selected, in which the selection of the processes is stored in the first database and in which the selected processes are called up via the data network from a large number of spatially separated workstation computers and are displayed on the workstation computers as the basis for work processes.
- Video transmission technologies, internet / internet communication and other transmission media are used.
- a combination of different processes is put together to achieve a production goal, an optimal combination being made possible with the help of the workstation computer.
- individual process steps can be compared with one another.
- a combination of process steps within a process flow is possible, and the comparison of different combinations gives the user an objective choice for an optimal combination.
- the feasibility of a planned process flow can be demonstrated with the combination and comparison of the individual processes and, for example, the costs and the time for an individual process flow can be estimated.
- Found solutions can be recorded using video-supported documentation and can be called up as a reference for production sites via the data network and displayed on workstations. Using the reference documentation, a work process can be individually designed in individual production locations.
- the method according to the invention also permits employee training with the aid of the standard process sequences found.
- the selected process flows are marked in the database and are available as text, data, videos or other multimedia content.
- a comparison of process sequences can be made, for example based on the time required carry out. This comparison can be carried out either by a trained employee or automatically by the computer. By using a reference basis, a computer is able to automatically compare all possible process combinations with one another and select the cheapest combination. It is also possible for a large amount of data to be stored and used for the evaluation. For example, cost data is data that reflects the cost of a process. Additional process parameters that are helpful for automatic evaluation can also be saved with the process data.
- Process flows can be planned in great detail if, with the help of the process data, working methods, work flows, production flows, work place data, material data, equipment arrangements, quality data, test regulations and / or
- the database can be changed continuously. If, for example, an error is found in the process flow planning during an implementation in a production site, the selected process can be iteratively optimized by comparison with the real process, and this optimized process is saved in the database. The optimized process is then available to all connected workstations for further planning. This ensures knowledge transfer between individual production sites. Thanks to the central data management, changes are always available to all connected workstations.
- Costs for the implementation of a process flow in a production site can be reduced by using the database to create an experience base, whereby the optimal process is stored in the database. Once errors have been made, the optimal process can be avoided. With each new site planning, the experience of to use location planning. Even with parallel location planning, the database enables experiences that have already been made to be used in other locations.
- Processes can advantageously be compared with one another if process data are combined into different process groups in the database and if the process data of individual process groups are stored in a standardized manner, which facilitates a comparison between individual processes of a process group.
- Different assembly methods, different production routes, different material routes and the spatial arrangement of a workplace can be summarized under a process group.
- a process For a complete process flow, a process must be selected from a process group. All combinations of process data of the individual process groups can be carried out automatically in an iterative process. As a result, the optimal process can be determined automatically.
- the standardization of individual processes within a process group makes it easy to compare these processes, since key data are always available that allow a comparison.
- a standard for a process flow can be formed.
- the process ensemble represents the optimal process flow.
- the complete process flow is simulated and it is ensured that it is the optimal one.
- Another object of the invention is the use of a method described above in the planning and development of a motor vehicle production.
- Figure 1 shows the schematic structure of a system for implementing the method according to the invention.
- FIG. 3 shows a flow chart of a method according to the invention.
- 1 shows process data 2a-e, a database 4, a data network 5, an evaluation unit 6, production sites 8 and method steps AE.
- process data 2a-e are fed into database 4 in method step A.
- the process data include various assembly methods. All possible assembly methods are stored in database 4.
- the process data 2 a relate to quality specifications and the process data 2 b relate to different work paths that are necessary for the production of a workpiece. All possible ways of working are stored in the database. Possible material paths are recorded as process data 2c and stored in the database 4.
- the process data 2d contain possible workplace designs, which are also stored in the database 4. Tips and tricks for individual processes are stored in the database 4 as additional process data 2e.
- process data 2 After all process data 2 have been stored in the database 4 and have been assigned to the process groups 2a, 2b, 2c, 2d and 2e, they are transmitted to the evaluation unit 6 via the data network 5 in work step B.
- the evaluation unit 6 carries out the comparison of all possible combinations of process data 2 from the individual process groups in an iterative process. An optimal process flow is found when the time of a complete process flow, the resulting costs and other process parameters are within a target window.
- the individual production sites 8a-c can call up the optimal process flow with the process data 2.
- the optimal process flow contains a preliminary production plan, which is managed centrally. With the help of the optimal process flow, methods can be planned and proof of feasibility can be provided with regard to the target window.
- the process data of the optimal process flow include the process flow as well as data, texts and multimedia content.
- the parameters for individual process data 2 can be specified for each production site and special plans can be created taking into account the local requirements and restrictions.
- one process can then be performed on one Use a concrete workflow, whereby the employees can be trained with the help of process data 2, for example the multimedia content, production teams can receive time specifications based on the optimal process flow and can perform optimized assembly processes based on the optimal process flow. Thanks to the multimedia content, the optimal process flow can be efficiently communicated and documented. This defines a reproducible scale. A quick and high quality start of production is guaranteed. If during the implementation of a process flow in a production facility 8b it turns out that individual process data or parts of a process flow are not optimal, the experiences and changes made can be transmitted to the database 4 in a method step E. These changes are available to the other production sites 8a, c, so that the same errors do not occur repeatedly.
- FIG. 2 shows a display window 10 which has sections for a video display 12, process data 14, process flows 16 and process evaluation 18.
- a process sequence is shown in the display window 10 in the video display 12 with the aid of multimedia content.
- the visual representation of a process flow can be easily conveyed to an employee. He can understand how the optimal process should work.
- the process data 14 are shown in a further window. These contain information about the respective process, the process duration, the process costs, the process identification and other process-relevant data, such as information on quality, logistics and work instructions.
- Process flow 16 is shown in a further window. For each process flow, the individual work steps are displayed sequentially and chronologically, for example by text information.
- An evaluation 18 of a process can be carried out in the last window. The evaluation 18 shows the total time of a process flow, costs of a process flow, duration of individual process sections and further data.
- FIG. 3 shows a flow diagram of a method according to the invention.
- a database 20 provides data for an iterative comparison 22.
- the result of the iterative comparison 22 is used to compile a process ensemble 24, which is saved 26 in a further step.
- the database 20 provides 22 process data of all process groups for the iterative comparison.
- the iterative comparison 22 is carried out until an optimal combination of processes of individual process groups is found and thereby a process flow within set targets.
- the process ensemble is assembled in a further step 24.
- the process ensemble 24 After the process ensemble 24 has been assembled, it is stored in the database 26. An optimized process sequence is then available for a large number of production sites ,
