Sensor-Integrated Hybrid Blockchain System for Supply Chain Coordination in Volumetric Modular Construction

Volumetric modular construction (VMC) needs streamlined supply chain coordination to achieve its full potential benefits, such as reduced schedule and cost, with consistent quality. Studies have noted that blockchain technology has significant potential for increasing the efficacy of supply chain coordination by providing reliable information sharing among VMC stakeholders. However, it is not well known how blockchain technology’s enhanced information sharing ultimately can lead to better supply chain coordination in VMC. To address this issue, we developed and tested a blockchain-based information collecting, storing, and sharing system with an automated contract execution method. A sensor-integrated decentralized application collects project information and sends it to the blockchain network to be shared among project participants for data-driven actions in VMC. We demonstrated the system through a …
