Adaptability and changeability are becoming the key features of future manufacturing. With adaptability comes a need to dynamically and frequently change factory topologies throughout the life-cycle of manufacturing systems. These changes are necessary to respond to changes in markets that result in new products, production volumes, and product variants. In addition to flexibly switching between different setups, the resulting schedules still have to be optimal to a certain extent to stay profitable. In this paper, we extend a capability-based planning approach to generate timed automata models that are used to solve the scheduling problem. The capability-based approach automatically generates an action sequence that defines all necessary production resources and operations for a product. The action sequence is then automatically transformed into models in UPPAAL -a model-checker for timed automata -and used to generate a schedule for production orders. The result can then be executed on the different production resources. An example scenario based on an industrial production system used for educational purposes shows the suitability of this approach.

“…The user can set-up the factory using the stations he wants to include. These stations log onto a planning and scheduling system autonomously as described in previous work [20]. Afterwards, the user can choose the different products that should be produced and the system automatically generates a feasible schedule and controls the production.…”

Abstract-Future manufacturing systems are required to be adaptable and react quickly on changes in markets and demands. Additionally, they should be able to support individualized products that are tailored to customer needs. Flexibility can be increased through decoupling product descriptions from manufacturing systems. Production processes are no longer described based on available resources. Instead, a generic description with all required parameters is defined once and later used with different factory setups. We propose a list of parameters and information that should be included in such a generic product description. Afterwards, we define possible structures for product descriptions that can typically occur in manufacturing systems. We evaluate the approach on an experimental setup used for educational purposes.

Developers of embedded systems are increasingly facing requirements concerning adaptivity. The term adaptivity covers several different aspects. In this paper, we present an innovative open-source run-time system that enables adding and removing applications and adapting to changes in the hardware topology while still guaranteeing traditional requirements of embedded systems such as real-time or safety. The system uses a data-centric approach to achieve a modular application design and to enable the interaction of application components created by independent developers. Using a requirements-centric approach, the system can reserve the resources such as processor time, memory or network bandwidth required by application components. New applications can only be added if enough resources are available. The paper details these concepts and presents the architecture of the run-time system.
