There are more than 450 automated production stations – from body-shell work to assembly – in Daimler’s C-class production plant in Bremen. In order to keep everything in view, control systems map the entire production flow and make it possible to see the whole factory at a glance.
If a machine breaks down or some other disruption occurs, this can be seen in the control system. However, the system does not indicate the resulting effects. Are there likely to be bottlenecks in the early shift? At which station? Will the output targets be reached? The greater the complexity of a production line, the more difficult it is to assess the overall impact of a disruption.
This situation will soon change: The world’s first agent-based production control system ProVis.Agent® controls and monitors the Mercedes C-class assembly lines. “The system works out what the worker in the control room needs to do in order to achieve the defined output target: for instance by postponing a scheduled break, redeploying the workers on the production lines, or changing the sequence of the vehicles at short notice,” explains Dr.-Ing. Olaf Sauer, head of the control systems business unit at the Fraunhofer Institute for Information and Data Processing IITB in Karlsruhe, where ProVis.Agent was developed.
Conventional shopfloor-related software systems are not usually interlinked, which means that information has to be painstakingly and to some extent manually collected and interpreted. “A new generation of shopfloor-related IT systems has become established to ensure that planning systems and operative control systems interact smoothly. They are known by the collective term of ‘manufacturing execution systems’, or MES for short, and their components are interlinked by software agents or services,” explains Sauer.
The system was recently commissioned at the press shop in Bremen. “This is the first time we have ever been able to integrate information from different press shop IT systems in the control system,” says Sauer. “There are cameras monitoring the scrap metal conveyers and the loading of wagons, and an operating data registration system monitors the presses and conveyers. The press shop uses automatically guided vehicles, a new inventory management system, and SAP for order management. Our integration platform combines all of these applications in a central control room for overarching operation and observation.”

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
