The article "Intelligent Manufacturing in the Context of Industry 4.0: A Review" by Ray Y. Zhong, Xun Xu, Eberhard Klotz, and Stephen T. Newman provides a comprehensive overview of the key concepts, technologies, and global movements in intelligent manufacturing within the framework of Industry 4.0. Industry 4.0, a German strategic initiative, aims to create intelligent factories through the integration of cyber-physical systems (CPSs), the Internet of Things (IoT), and cloud computing. These technologies enable manufacturing systems to monitor physical processes, create digital twins, and make smart decisions through real-time communication and cooperation with various elements. The paper reviews 165 papers from Scopus and Google Scholar databases, highlighting the evolution of intelligent manufacturing from 2005 to 2016. It discusses key technologies such as IoT, CPSs, cloud computing, big data analytics (BDA), and information and communications technology (ICT) that support intelligent manufacturing. The authors also examine worldwide movements in intelligent manufacturing, including governmental strategic plans from countries like the European Union, the United States, Japan, and China, as well as strategic plans from major international companies. The paper concludes by presenting current challenges and future research directions, aiming to inspire new ideas and advancements in the Fourth Industrial Revolution. The analysis of published data from 2005 to 2016 shows a steady increase in research on intelligent manufacturing, with significant spikes in publications in 2006, 2014, and 2015. The top sources, universities, scholars, and countries active in this field are also identified, with China, the United States, and the United Kingdom being the leading regions.The article "Intelligent Manufacturing in the Context of Industry 4.0: A Review" by Ray Y.
