An expert system in industry is an artificial intelligence-based system that applies domain-specific knowledge and rules to make informed decisions in manufacturing, maintenance, and industrial process control. These systems use knowledge bases, inference engines, and rule-based logic to provide expert-level recommendations.

Expert systems help industries diagnose equipment failures, optimize production planning, and automate quality control. They integrate with industrial IoT (IIoT) and data analytics platforms to enhance decision-making and operational efficiency.

As AI technology advances, expert systems are becoming more sophisticated, incorporating machine learning and real-time analytics. These systems improve process automation, reduce human error, and contribute to overall industrial efficiency and reliability.
