ABSTRACT

As a natural consequence of Industry 4.0 demands related to industrial processes control digitization, the smart manufacturing (SM) concept was enriched by integrating advanced technologies of digital information processing. This paper presents an original solution for improving the most representative instance of SM, namely, supply chain management (SCM), by using the most recent approach in hierarchical networked control systems (HNCS), that is Edge Computing. The paper presents both the software and hardware architecture of an Edge Gateway device which offers, on one hand, dual communication both on vertical (between the network layers from the local, inferior, represented by IIoT, to the central, superior, represented by the Cloud) and on horizontal (between similar devices located on the same Edge level) and, on the other hand, can locally process data to take fast decisions which facilitate real-time process control. The validity of the proposed solution is supported by a case study performed on a flexible assembly/disassembly line (laboratory model).

摘要

作为与工业过程控制数字化相关的工业4.0要求的自然结果，智能制造（SM）概念通过集成数字信息处理的先进技术而得到了丰富。本文提出了一种原始解决方案，该解决方案通过使用分层网络控制系统（HNCS）中的最新方法（即边缘计算）来改进SM的最具代表性的实例，即供应链管理（SCM）。本文介绍了Edge Gateway设备的软件和硬件架构，一方面，它提供了垂直的双重通信（从IIoT代表本地的本地网络到以IIoT代表的中央高级网络在网络层之间）。云）和水平（位于相同Edge级别的相似设备之间），另一方面，可以在本地处理数据以做出有助于实时过程控制的快速决策。在灵活的组装/拆卸生产线（实验室模型）上进行的案例研究证明了所提出解决方案的有效性。
