ProVis.Agent is the first agent-based production monitoring and control system for distributed real-time production monitoring. Its functionality is based on ProVis.NT, the proven object-oriented control system which monitors and controls e.g. the body, paint and assembly shops in DaimlerChrysler's (DC) automotive plant in Bremen, Germany. Forming an integral part of the manufacturing execution system (MES), ProVis.Agent for the first time allows to be integrated with other shop-floor related applications, such as body identification, worker information, sequence setup, etc. In this paper the authors show a case study of implementing agent-based technology to a classical field of automation. ProVis.Agent has been implemented and is currently in the test phase. It will be delivered to DC in April 2006 and start operation with the start up of new facilities for the new C-class model. A user-oriented assistant software that makes available the required functions and information for a specific working activity is essential for the users on the shop floor to take the required and expected decisions. For both, to prove the agent technology concept and to demonstrate such an assistant systems Fraunhofer IITB has developed a real time simulation system that calculates the production output regarding all actual production breakdowns indicated by the production monitoring system as well as the buffer status calculated according to the current production output. The simulation covers the 3 coming shifts. It has turned out that extending this simulations for more shifts (4 to 8) does not result in reliable predictions because of uncertainties arising from production breakdowns in future, which can not been foreseen exactly. The HMI for the production assistant has been implemented using the SCADA system WinCC. With the help of this assistant software, which is connected to the monitoring systems by a software agent, the shop floor people can react to failures on the shop floor level quickly and correctly. They are now able to adjust line speed and the work force for the coming shifts and to take efficient measures to keep the output as high as possible.
