Industry 4.0 concepts and implementation challenges: Literature Review

Industry 4.0 or smart manufacturing is an industrial revolution for the production systems that has a great impact on competitiveness and the various prompted lines of research. This new concept that allows to interconnect the machines between them (IOT) and facilitates production with a minimum of time and cost generates anomalies and research questions. In this paper, we will review the different research done on Industry 4.0 more specifically, literature reviews on the concept of Industry 4.0, its technologies, and implementation issues, to draw a tree structure that will help us to know and follow the different elements and technologies of this revolution, as well as the challenges of its implementation.
