Industrial requirements of modern, agile production aim at achieving intelligent behaviour andfast reconfigurability of the production system. Evolvable Production Systems (EPS) is anovel production systems paradigm, incorporating principles of modularity and adaptability.EPS uses process-specific modules, Ontologies and the EPS-knowledge base to enablethese characteristics. The thesis proposes a heterarchical control architecture, implementedas Multi-Agent System, to enable adaptation and evolution of the production system.Therefore agents are realized as software representations of physical production equipment.The implementation of EPS components (EPS-Ontology and knowledge base) areelaborated and the advanced behaviour of the Multi-Agent System is detailed: Selfawarenessof agents concerning their skills, based on the agent state representation,facilitates reasoning capabilities and advanced coordination strategies for production tasks.The thesis investigates the structure of the proposed multi-agent control architecture by asimulation of two heterarchical architectures on machine-level and evaluates dependenciesof efficiency and robustness related to organisational structures of the agent society. Finally,system reconfigurability, which is achieved by changing multi-agent interactions, iselaborated in detail. |
