    ENGLISH SUMMARY: With industry’s drive to adopt Industry 4.0 technologies, and their enabling technologies, in manufacturing processes, intelligent automated manufacturing has become largely sought after. With defining features such as robustness, reconfigurability and scalability, the Holonic Manufacturing Execution System (HMES) approach shows great potential to satisfy Industry 4.0 requirements. Implementations of these systems have been historically known to require great development effort and time. These implementations are however being aided by the development of holonic reference architectures, such as the Product-Resource-Order-Staff-Architecture (PROSA) and its recent revision the Activity-Resource- Type-Instance (ARTI) architecture. This thesis presents an ARTI-based HMES implementation. The implementation of this system is aided through the use of the Biography-Attributes-Schedule-Execution (BASE) architecture for digital administration shells. The BASE architecture was initially developed as a framework for the development of a digital administration shell for a human worker, in order to elevate the human worker to the level of a Cyber-Physical System. It was however proposed that the BASE architecture also had the potential to be used in a manufacturing context. The possibility of implementing the ARTI-based HMES using the BASE architecture for the respective ARTI holons is confirmed through a mapping of the ARTI architecture to the BASE architecture. The HMES is implemented on a Fischertechnik Industry 4.0 Training Factory, a small-scale manufacturing system, as a case study system. The complexity of the case study, which comprises several interacting subsystems, provides a good basis for evaluating the ARTI and BASE architectures for HMES development. The thesis concludes that the ARTI architecture provides a well-defined structure for the conceptual design of HMESs, while the BASE architecture effectively supports the implementation of ARTI-based HMESs with little additional development required.
