This analysis demonstrates the potential of ant colony algorithms to minimize cost and carbon emissions in prefabricated buildings.

The optimization approach resulted in a reduction in carbon emissions by 18.4%, indicating significant potential benefits.
Results showed a maximum reduction of 27.89% in duration, improving efficiency in project timelines.
The study utilized the ant colony algorithm to balance multiple objectives, including cost and emissions, effectively.
This method may enable a sustainable transition from traditional cast-in-place to prefabricated construction.

Xu et al. (2025) studied this question.
