Blockchain Network Model to Improve Supply Chain Visibility based on Smart Contract

Abstract

Due to the increasing complexity of supply chains over the past years, many factors significantly contribute to lowering the supply chains performance. Poor visibility is one of the major challenging factors that lowers supply chains performance. This paper proposes a Blockchain-based supply chain network model to improve the supply chain visibility. The model focuses in improving the visibility measurements properties: information sharing, traceability, and inventory visibility. The proposed model consists of information sharing, traceability, and inventory visibility platforms based on Blockchain technology smart contract. The model built with Hyperledger platform and extend the Hyperledger Composer Supply Chain Network (HCSC) model. The research is designed to three main phases. First phase: the preliminary phase which is the literature review phase to identify the existing challenges in the domain. The second phase: the design and implementation phase which is the development steps of the proposed research model. The third phase: the evaluation phase which represent the performance evaluation of the proposed model and the comparisons between the proposed model and the existing models. In the evaluation performance, the common performance metrics Lead time and average inventory levels will be compared in the proposed model, Cloud-based information system, and the traditional supply chain. These proposed platforms offer an end-to-end visibility of products, orders, and stock levels for supply chain practitioners and customers within supply chain networks. Which helps managers' access key information that support critical business decisions and offers essential criteria for competitiveness and therefore, enhance supply chain performance.

“…To increase supply chain visibility, Arwa Mukhtar et al proposed a blockchain-based supply chain network concept in 2020. Information sharing, traceability, and inventory visibility are the three visibility measurement qualities that the model focuses on improving [ 18 ]. The suggested approach includes platforms for data sharing, traceability, and inventory visibility built on top of blockchain technology.…”

A Systematic Literature Review of Blockchain-Enabled Supply Chain Traceability Implementations

“…For instance, in [39] the authors combine blockchain and a real-time event-monitoring system to track and disseminate emergent knowledge for preemptive management purposes. To improve visibility, the authors in [40] propose a blockchain-based SC network model. The proposed model consists of platforms for information sharing, traceability, and inventory visibility based on smart contracts.…”
