The detailed literature review method uses a step-by-step article selection method, including: database selection, keyword selection, article collection, inclusion/exclusion criteria and selected article reviews. Most work is based on concepts or case studies. However, empirical research is needed in this area. The future research directions provided in this document may be helpful to researchers who are willing to conduct research in the field of Industry 4.0. Researchers related to Industry 4.0 have aroused great interest, leading to many publications on different Industry 4.0 topics. This document will help to obtain future research directions. Keywords: Digital Transformation, Industry 4.0, Barriers, Cyber Physical System, Smart Factory, Internet of Things II. REVIEW METHODOLOGY Reviewing the literature is an important part of any research work. Through literature review, the relevant literature is evaluated and analyzed to find out the research gaps that help strengthen the research field. Use various available databases related to knowledge exchange, knowledge transfer and knowledge flow for literature review. To this end, the author has submitted various articles to the database, i.e., Web of Science (WoS) and ProQuest, which contain a large number of well-known publications, such as Emerald, Taylor and Francis, Springer, IEEE and Elsevier. The structured review method uses a five-step process, as shown in Figure 1. Develop a search strategy by first looking at the relevant data source (ie the database). In order to access various academic and conference publications, Web of Science and ProQuest databases were selected. I. INTRODUCTION The fourth industrial revolution, Industry 4.0, brings a new perspective to the manufacturing industry, which can be combined with emerging technologies to achieve efficient production and optimize the use of resources in the manufacturing industry. The German government's Industry 4.0 plan merges manufacturing and IT (Kamble et al., 2018). The first industrial revolution began with the introduction of the steam engine, the second batch of industrial revolutions focused on mass production, and the second industrial revolution began with the development of computer technology. The digital revolution began with the development of computerization and the creation of networks in all areas of production, which led to the fourth industrial revolution. Industry 4.0 can be defined as the integration of information technology and cyber-physical systems (CPS). Emerging technologies such as smart machines, cloud computing, and data-sharing production facilities trigger actions and controls independently of each other, creating a cyber-physical system (CPS). Any organization with Industry 4.0 has great potential to realize social and economic benefits and integrate the use of artificial intelligence, the Internet of Things (IoT) and big data. As the Internet of Things (IoT) improves the way CPS interact, monitor, control, and manage, CPS facilitates the integration of processes and systems into organizational and manufacturing technologies. It can improve cooperation and communication between production departments, innovate production, improve services, improve logistics, and carry out effective and cost-effective resource planning [31]. The latest development of ICT tools has promoted the development of Industry 4.0. The development and progress of emerging technologies in Industry 4.0 will provide a series of feasible solutions to meet the growing needs of the manufacturing industry. First of all, the idea of the “fourth industrial revolution” may sound better [36]. It should be noted that its implementation involves many challenges, risks and obstacles. Defining the correct infrastructure and standards, ensuring data security and training employees are some of the problems that need to be solved on the road to Industry 4.0 (Hofmann & Rüsch, 2017). Therefore, it is necessary to determine the current research status and future scope of Industry 4.0. This research attempts to focus on the latest works published from January 2017 to April 2021. This article reviews a total of 36 articles and research papers, which were published in different journals. In addition, the structure of the document is as follows. A detailed review of the literature in tabular form. The next section provides research methods for selecting articles, followed by the discussion in section 3. The conclusion is provided in the last part of this article.
