Timber construction and prefabrication are becoming increasingly important in the building and construction industry. The degree of automation in this area is low. Caused by the great variability of construction projects and building components, automation systems that can adapt flexibly to different construction projects are required. However, a system that fulfills these conditions does not yet exist. Down-times for reconfiguration in between projects must be short. The use of robotics for the automation of prefabrication is constantly developing. Recent publications present a novel, flexible, reconfigurable, and transportable manufacturing platform using industrial robots. A system consisting of several of these modular platforms can be flexibly adapted to the changing requirements of different construction projects and set up on-site at local timber construction companies. To ensure the manufacturability of the timber components and to minimize downtimes between projects, the entire workflow from digital design to fabrication must be considered. The co-design approach makes this possible. It breaks up the currently existing sequential process from design to fabrication and considers all sub-steps holistically. Thus, enabling the consideration of the fabrication capabilities during building design. This allows the planning of building components and system layout so that fabrication is feasible. To achieve this, the fabricability of a given system layout has to be evaluated. This requires a digital twin of the fabrication system as a simulation model. The reconfigurability of the fabrication system must be reflected by the digital twin. The fabrication tasks and the system configuration are constantly changed in search of a valid combination. Therefore, with each iteration, the digital twin must be adapted or newly created. At present, this is mostly a manual process. This makes the whole approach unfeasible. To solve this problem, this work presents an approach
The increasing digitization of the manufacturing industry offers a wide range of opportunities for the effective use of production data, which can lead to significant time and cost savings. One promising approach is t...

In the past 10 years a research cluster in engineering science has been set up to create completely new materials as well as appropriate machines and production processes. To support the collection, storage and analysis of complex process data within that cluster several IT & process management methods and tools have been developed. Now entering the final stage of the cluster, the focus changes to the efficient usage of the created knowledge. To support the technology transfer process the previously created methods and tools are enhanced. In this paper, a software system supporting the controlled and secure transfer of engineering knowledge from research to industry is presented.
This paper compares online device discovery and remote startup and shutdown solutions for an enterprise network. As some of for these solutions do only work in a local network and the enterprise network consists of se...
