Hitachi introduces AI-based predictive maintenance service

Japanese technology firm Hitachi has introduced a new predictive maintenance service for petrochemical plants that are powered by artificial intelligence (AI) technology. The new solution automatically categorizes and evaluates the operation status in petrochemical plants to prepare real-time detection of changes in conditions and abnormalities, which may indicate failures. After gathering operation data and analyzing using an adaptive resonance theory (ART), the service detects abnormalities in devices and equipment that are usually difficult to be detected by prediction models or human judgment. The new service is expected to help chemical companies ease the workload of operators when monitoring the plant’s operation.
