Enabling Technologies and Current Research Scenario of Industry 4.0: A Systematic Review

Abstract

This research was carried out to review the Industry 4.0 enabling technologies. This study incorporates the recently published research articles on Industry 4.0 enabling technologies and applications of these enabling technologies. To perform this research work, bibliometric analysis was carried out. Further, content analysis was used to identify the various domains within the literature on smart manufacturing. These techniques were used to identify the current trends, various research works and the contribution of researchers in Industry 4.0 domain. It was observed that many research articles on Industry 4.0 are theoretical in nature which did not give a strong benchmark for policymakers. It was found that Germany was the leading country in the publication of research articles on Industry 4.0 followed by USA, UK, and China.
