Assembly Process driven Component Data Model in Cyber-Physical Production Systems

Abstract — In times of global markets, the cost pressure on manufacturing companies in high-wage countries is increasing. One way to deal with globalized markets is to develop new production systems. The German Federal Government supports an initiative for the research on highly adaptable, cyber-physical production systems called Industrie 4.0 . In cyber-physical production systems components communicate with assembly stations and other components to guarantee the ideal manufacturing process. As part of this initiative the description of communication and decision processes in the assembly systems is researched. Therefore a UML based modeling method is chosen to model the communications and material flows in such a system. The component data model is one central element in the process. In the model knowledge about the individual components can be stored and used to make decisions in the assembly process. During the communication process components exchange
