A Distributed Software Agent-centric Framework for Supply Chain Networks Empowered by Blockchain: Insights into Smart Contracts

The advent of Blockchain Technology (BCT), along with the use of smart contracts, has triggered a transformative phase for Supply Chain Networks (SCNs). In this work, we propose a distributed, smart contract-based Supply Chain Management (SCM) framework meticulously designed to monitor and control discrete operational phases in supply chains. Further, a software agent-based approach has been adopted for tracking supply chain operations, from the initiation of a purchase order to its final delivery. This research strives to establish a comprehensive framework for applying a Multi-Agent System (MAS) infused with BCT. A number of agents with specified roles have been deployed with a well-defined interaction architecture to drive the supply chain operations. The agents engage in effective coordination and monitoring of SCN activities. The overarching goal is to boost SCN performance in reliability, scalability, transparency, traceability, and resilience, mitigating deficiencies and enhancing overall efficiency.
