Digital Twin Representations of Concrete Modules in an Interdisciplinary Context of Construction and Manufacturing Industry

摘要

Based on the knowledge gained from mechanical engineering and research activities in the context of Industry 4.0, innovative, modular building construction approaches based on flow production methods must be based on a real-time life-cycle-oriented management of information about products, production processes and created systems. To enable rapid, individual, precise, and fault-tolerant production of flexible modules made of free-formable high-performance concrete, data from the ongoing production process and data describing the current status of the module must be continuously collected, combined and made available. Based on this information, the individual production steps can be fine-tuned and the utilization of the machines better planned. Furthermore, it can be verified, whether the current status of a produced module still meets the previously defined requirements from engineering. A state-of-the-art literature review and comparison for digital twin concepts from both involved domains, construction as well as production, is presented in the paper. The contribution gives insights of the requirements elicitation for the formal description of the product requirements in terms of function and quality, considering the possible uncertainties in the course of production. Furthermore, it shows a draft concept for the administration shell for digital twins comprising integrated and adaptable data and interaction models for the industrialized production of high-performance concrete modules.
