Review of research issues and challenges of maturity models concerning industry 4.0

Abstract Over the years, technological developments and innovation in the area of manufacturing have evolved which is known as industry 4.0(I4.0), and has increased the consideration of all the researchers, enterprises and countries. Manufacturing enterprises are facing manifold challenges arising due to their internal and external situations. Similarly, choices have to be made among various available disruptive technologies, like IoT (Internet of Things), CPS (Cyber-Physical Systems) and cloud-based production. Thus, the need of the hour for manufacturing enterprise is to understand Industry 4.0, subsequently, it is necessary to assist the manufacturing enterprises to assess their Industry 4.0 preparedness. German’s National Academy of Science and Engineering (acatech) has developed Industry 4.0 Maturity Assessment for establishing manufacturing enterprises Industry 4.0 maturity and identifying areas where actions are required to realize higher maturity stage in implementation of Industry 4.0. In this article, a review of literature is made to comprehend the concept of Industry 4.0, and with focus on maturity models. Furthermore, the articles discuss the challenges, research gaps between the current status of manufacturing and I4.0. The findings of this review article may be the basis for understanding the challenges and designing a maturity model considering various dimensions of I4.0.
