ABSTRACT

Traceability has become a critical element in supply chain management, particularly in safety-sensitive sectors like food, pharmaceuticals, etc. Upstream (manufacturers, producers, etc.) and downstream (distributors, wholesalers, etc.) supply chain members need to store and handle traceability-related information for providing proof of regulatory compliance to both state authorities and more demanding customers. Consumers also place high expectations on food supply chains (FSC) with specific emphasis on facets related to safety. However, the complexity of modern FSC networks and their fragmentation act as barriers for the development of sound traceability mechanisms. In this paper a distributed trustless and secure architecture for FSC traceability is developed and tested. For assessing the feasibility of the proposed approach, a food traceability case study from a dairy company is presented. The applicability of the model is further illustrated by the development of fully functional smart contracts and a local private blockchain. Moreover, the various links between the proposed blockchain-based model and its managerial implications are presented. The overall benefits of the proposed model are discussed along with fruitful areas for future research. The results are of significant value to both practitioners and researchers.

摘要

可追溯性已成为供应链管理的关键要素，尤其是在食品、药品等安全敏感部门。上游（制造商、生产商等）和下游（分销商、批发商等）供应链成员需要存储和处理与可追溯性相关的信息，以向国家当局和要求更高的客户提供合规证明。消费者还对食品供应链 (FSC) 寄予厚望，特别强调与安全相关的方面。然而，现代 FSC 网络的复杂性及其碎片化是健全可追溯机制发展的障碍。在本文中，开发和测试了用于 FSC 可追溯性的分布式去信任和安全架构。为了评估所提议方法的可行性，介绍了一家乳制品公司的食品可追溯性案例研究。功能齐全的智能合约和本地私有区块链的开发进一步说明了该模型的适用性。此外，还介绍了提议的基于区块链的模型与其管理影响之间的各种联系。讨论了所提出模型的整体优势以及未来研究的富有成果的领域。结果对从业者和研究人员都具有重要价值。讨论了所提出模型的整体优势以及未来研究的富有成果的领域。结果对从业者和研究人员都具有重要价值。讨论了所提出模型的整体优势以及未来研究的富有成果的领域。结果对从业者和研究人员都具有重要价值。
