Industry 4.0 and Enabling Technologies: Integration Framework and Challenges

Industry 4.0 has revolutionized the traditional production line toward smart factories in a sustainable environment. It represents an intelligent manufacturing network, where machines and products interact without human control. Recently, there have been studies on Industry 4.0 and integrating enabling technologies, and this article aims to summarize a few of the pathbreaking studies and guide future research in this field. This paper reviews 112 journal publications related to Blockchain from 2017 to 2021 in the Science Citation Index (SCI) and Social Science Citation Index (SSCI) database. The selected papers are grouped into ten categories. This overview indicates that research of integrating Industry 4.0 enabling technologies needs to focus on developing better privacy and security mechanisms and a design framework for integrating the 5G network system into the platform.
