INTRODUCTION The fourth industrial revolution, commonly known as Industry 4.0, has ushered in a new era of smart manufacturing and industrial operations. At the heart of this transformation lies the convergence of Artificial Intelligence (AI) and the Internet of Things (IoT), which has given rise to unprecedented opportunities for optimizing industrial processes, particularly in the domain of maintenance [1]. Traditional reactive and preventive maintenance approaches are increasingly being replaced by more sophisticated predictive maintenance strategies, leveraging the power of AI and IoT technologies [2]. Predictive maintenance, enabled by AI and IoT, aims to forecast equipment failures before they occur, allowing for timely interventions that can significantly reduce downtime, extend machinery lifespan, and optimize maintenance costs [3]. This approach represents a paradigm shift from traditional maintenance practices, moving from fixed schedules or reactive responses to data-driven, proactive strategies [4]. The integration of IoT devices in industrial settings has led to the creation of vast sensor networks capable of continuously monitoring equipment health, environmental conditions, and operational parameters [5]. These sensors generate massive amounts of data, which, when analyzed using advanced AI algorithms, can reveal patterns and anomalies indicative of impending failures or performance degradation [6]. This paper aims to provide a comprehensive review and analysis of AI-driven predictive maintenance in IoT-enabled industrial systems. We explore the various AI techniques employed in this domain, including machine learning, deep learning, and reinforcement learning, and their applications across different industrial sectors. The study also examines the challenges associated with implementing these technologies and the potential solutions to overcome them. The rest of this paper is organized as follows: Section 2 provides a background on predictive maintenance and its evolution in the context of Industry 4.0. Section 3 delves into the role of IoT in enabling predictive maintenance. Section 4 explores various AI techniques used in predictive maintenance. Section 5 presents case studies from different industrial sectors. Section 6 discusses the challenges and opportunities in implementing AI-driven predictive maintenance. Section 7 outlines future research directions, and Section 8 concludes the paper.
