## 4 Qualitative Analysis
### Construction Phase
#### 4.3.5 Automated Assembly  
Automated assembly, facilitated by an array of digital technologies, including RFID, BIM, AR, digital twins, and robotics, aims to enhance the installation of precast elements, foster intelligent assembly through human-machine collaboration, and enable customized automated assembly processes. By harnessing these technologies, the industrialized construction process can reduce manual operation errors and achieve higher efficiency.  
One strand of research centers on various tools to augment the productivity of field workers. This requires dynamically adapting the operational strategy to current information and updates in environmental conditions. [PERSON] et al. [85] introduced a dynamic information support system that utilizes RFID to identify available resources and a multi-agent system to collect actual conditions, generate alternatives, and provide dynamic information appropriate for the assembly sequence. [PERSON] et al. [86] proposed an AR interface to coordinate human artisans with robotic manufacturing cells, thereby streamlining prefabricated timber assembly. Additionally, [PERSON] et al. [87] used digital twins and VR to enhance assembly training and working practices in automated building environments.  
Another avenue of research focuses on modular assembly employing industrial robots. For instance, [PERSON] et al. [88] outlined the on-site robotic assembly of desert habitat structures, laying the groundwork for the robotic assembly of custom modular buildings. Complementarily, [PERSON] et al. [89] proposed an approach linking robotic assembly with the in situ 3D printing of custom connections for building components. Furthermore, [PERSON] et al. [90] integrated digital fabrication and robotic assembly to automate the assembly of semi-custom fit-out modules, achieving automated assembly for individual spaces through digital connectivity across the design, manufacturing, and construction processes.  
The current status of research on the construction phase of industrialized construction can be summarized as follows. First, information communication aims to improve visibility, transparency, and collaboration by standardizing component naming and ensuring data interoperability among stakeholders. Challenges such as inefficient information transfer and potential data loss can be addressed through the implementation of blockchain and IoT platforms. Second, construction scheme planning utilizes VR, BIM, and other digital tools for schedule estimation, performance tracking, and disruption detection. Dynamic risk modeling, in particular, reflects the interrelationships between risk variables and their impact on assembly performance. Third, logistics management employs algorithms and simulations to assess the economic and environmental impacts of supply chain solutions. Fourth, safety monitoring integrates digital technologies to enable hazard assessment and mitigation, though issues related to coverage and data transmission require further attention. Finally, automated assembly focuses on robotic assembly and the use of technologies such as AR and VR to enhance assembly practices in automated environments.
