Ontology-based assembly sequence planning optimization in modular integrated construction manufacturing
Year: 2025
Type: conference-paper
Abstract: Modular integrated construction (MiC) is recognized as an innovative approach that can help increase productivity in the construction industry. The manufacturing phase of a MiC project plays a significant role in production time, cost, and quality. An interesting observation is that the current production process in MiC factories still follows a similar and long-established construction paradigm and doesn’t enjoy the factory setup. A question is raised for MiC manufacturing whether the assembly sequence can be optimized or even revolutionized to embrace robotics and automation. This paper proposes an ontology-based assembly sequence planning optimization in MiC manufacturing to discuss the possible sequence rearrangement strategies. Firstly, an ontology, representing the assembly operations, the original work sequence, the absolute connection, the optimization connection, the geometrical constraint, and the spatial topological relations, is developed considering the characteristics of MiC manufacturing. Secondly, the assembly sequence planning can be optimized based on the developed ontology. Finally, three hypotheses are proposed to discuss the possible optimization results. The results can benefit production planning and improve productivity for the complicated manufacturing process of the MiC project.
