Abstract
The increasing competition between manufacturers, the shortening of innovation
cycles and the growing importance of resource-efficient manufacturing demand a higher
versatility of factory automation. Service-oriented approaches depict a promising possibility
to realize new control architectures by encapsulating the functionality of mechatronic
devices into services. An efficient discovery, context-based selection and dynamic
orchestration of these services are the key features for the creation of highly adaptable
manufacturing processes. We describe a semantic service discovery and ad-hoc orchestration
system, which is able to react to new process variants and changed contextual information
(e.g., failure of field devices, requirements on the consumption of resources). Because a
standardized vocabulary, especially for the description of mechatronic functionalities, is
still missing in the manufacturing domain, the semantic description of services, processes
and manufacturing plants as well as the semantic interpretation of contextual information
play an important part.
