The Role of Artificial Intelligence in Industry 4.0: Overview, Challenges and Outlook

Abstract

Artificial Intelligence (AI) has become the core technological pillar of Industry 4.0, enabling intelligent, autonomous and interconnected systems. This paper examines the role of AI in Industry 4.0 by synthesising applications, identifying key challenges that hinder widespread adoption and presenting future outlooks. While AI offers significant benefits in terms of operational insight, predictive capabilities and system optimisation, challenges around data quality, interoperability, transparency and workforce readiness remain unresolved. It is necessary to align AI innovation with workforce development and sustainability to achieve resilient and adaptive Industry 4.0 ecosystems. The study also explores future directions, highlighting the importance of human-centred AI systems, standardised frameworks, regulatory policies and sustainable industrial intelligence.
