Abstract
Off-site construction (OSC) projects rely on a smooth off-site supply chain. Previous studies improved supply chain management (SCM), while scantly mentioning business flow and recent advanced technology. This paper proposes a three-layered cyber-physical internet (CPI)-based platform for practical OSC-SCM. The scalable layer connects resources via an industrial driver (ID) for an information chain. The kernel layer designs protocols for digital twins (DT) and twin networks with incentive and information sharing mechanisms. The application layer offers thirteen services for offsite plant, logistics, and on-site assembly. A case study demonstrates 20% reduced construction time and millions of cost savings, proving enhanced efficiency.
