Abstract
Disruption risks may arise in a project-based supply chain due to the involvement of various actors, e.g. suppliers and transport service providers, along the chain besides its decentralised structure. This paper addresses monitoring the project completion time estimates at different stages of a project lifetime through tracking package ownership transfer events. We track the ownership transfer events by employing blockchain technology and smart contracts. Blockchain technology offers data security and builds trust along the supply chain. Consequently, a blockchain-enabled tracking system for package ownership transfer enhances real-time monitoring of project completion time estimates. In addition, this paper uses a simulation-based approach to quantify the acquired benefits from a real-time blockchain-enabled traceability system in a project-based supply chain. The proposed approach considers a straightforward supply chain consisting of two parties. Our proposed approach examines multiple disruption scenarios to assess the impact of blockchain technology integration on the project completion time estimates accuracy. The results show, for all scenarios, the superior performance of the blockchain-enabled traceability system compared to the baseline model with limited tracking of ownership transfer events.
