The next-generation technologies enabled by the industry 4.0 revolution put immense pressure on traditional ISA95 compliant manufacturing systems to evolve into smart manufacturing systems. Unfortunately, the transformation of old to new manufacturing technologies is a slow process. Therefore, the manufacturing industry is currently in a situation that the legacy and modern manufacturing systems share the same factory environment. This heterogeneous ecosystem leads to challenges in systems scalability, interoperability, information security, and data quality domains. Our former research effort concluded that blockchain technology has promising features to address these challenges. Moreover, our systematic assessment revealed that most of the ISA95 enterprise functions are suitable for applying blockchain technology. However, no blockchain reference architecture explicitly focuses on the ISA95 compliant traditional and smart manufacturing systems available in the literature. This research aims to fill the gap by first methodically specifying the design requirements and then meticulously elaborating on how the reference architecture components fulfill the design requirements.
工业 4.0 革命带来的下一代技术给传统的 ISA95 合规制造系统带来了巨大的压力，要求它们必须演变成智能制造系统。不幸的是，旧的制造技术向新的制造技术的转变是一个缓慢的过程。因此，制造业目前正处于遗留和现代制造系统共享相同工厂环境的情况。这种异构的生态系统导致了系统可扩展性、互操作性、信息安全和数据质量领域的挑战。我们之前的研究工作得出的结论是，区块链技术具有解决这些挑战的有前途的特性。此外，我们的系统评估显示，大多数 ISA95 企业功能都适合应用区块链技术。然而，文献中没有明确针对符合 ISA95 标准的传统和智能制造系统的区块链参考架构。本研究旨在通过系统地指定设计要求，并详细阐述参考架构组件如何满足设计要求来填补这一空白。
