Review analyzes Industry 4.0 technologies, highlighting applications and challenges in manufacturing, suggesting future research directions.
Industry 4.0 represents the integration of digital technologies such as the Internet of Things (IoT), automation, artificial intelligence, and data analytics into modern manufacturing systems. This review paper presents a comprehensive analysis of Industry 4.0 technologies and their applications in manufacturing industries. More than 30 peer-reviewed research articles published between 2013 and 2024 have been reviewed to identify key technological trends, industrial applications, benefits, and implementation challenges. The study highlights how Industry 4.0 enhances productivity, flexibility, quality, and decision-making in manufacturing environments. In addition, the paper discusses current limitations and identifies future research directions, particularly for small and medium-scale industries. This review aims to provide researchers and practitioners with a structured understanding of Industry 4.0 adoption in manufacturing.
