Predictive Maintenance in dynamic environments poses significant challenges, including data and concept drifts, lack of labeled data, and the constraints of streaming environments. To address these, our approach leverages unsupervised anomaly detection techniques to monitor asset states, eliminating the dependency on labeled datasets. Auto-configurable solutions ensure robustness against data drifts and enhance usability for end-users. Additionally, context-aware methods are employed to provide explainability and improve decision-making processes. All solutions are designed for online deployment, enabling real-time analytics and swift responses.
