The paper deals with research efforts which are subsumed in the term Cyber-Physical Production System (CPPS). An overview over SEPIA CPPS test-bed is given. Subsequently some aspects of this software architecture are described with more details, namely the extension to the Contract Net Protocol and semantic data model for information storage. The test-bed and its software architecture is then used in two exemplary applications for event processing and factory visualisation in 3D.
System SEPIA is a research test-bed for a state-of-the-art production control system. It is built from competitive off-the-shelf hardware and software components.
An important property of cyber-physical production systems is the high degree of distribution of the participants in the system. Therefore communication and coordination between distributed manufacturing plants is an important research topic.
It is shown that technologies from data stream management systems can be used in manufacturing systems for visualisation and quality management. Those technologies can easily be integrated in the open SEPIA software agent system architecture.
