Special Issue Information

Dear Colleagues,

With the increasing complexity of industrial applications and safety-critical infrastructure, fault tolerance and failure management in computing systems are becoming increasingly important. Prognostic and Health Management (PHM) provides essential methods for fault prediction, fault diagnosis, and system health assessment, thereby achieving resilient and reliable system operation. With the rapid development of artificial intelligence, the integration of large-scale models has brought new opportunities for intelligent operations and maintenance, achieving breakthroughs in accuracy, adaptability, and decision support.

This Special Issue is dedicated to high-quality research on the theory, methods, and applications of fault tolerance and failure management in the context of PHM. We particularly encourage research that integrates advanced computing, fault-tolerant design, and large-model-driven intelligent operations and maintenance for next-generation industrial systems.

This Special Issue will publish original research papers in the following interdisciplinary areas:

  • Data-driven Prognostic and Health Management (PHM);
  • Fault Mechanism Analysis;
  • Intelligent Fault Monitoring and Diagnosis;
  • Prediction of Remaining Useful Life;
  • Large-Language-Model-Driven Intelligent Operation and Maintenance;
  • Digital Twins for PHM Systems;
  • Applications of PHM in Aerospace, Energy, Transportation, and Manufacturing;
  • Explainable Anomaly Detection Methods;
  • Reliability Modeling and Assessment of Complex Systems.

Rolling element bearing failure in industrial robots can cause system downtime, high repair costs, and significant economic losses. Traditional fault diagnosis methods assume that training and testing data follow the same distribution, requiring extensive historical data, which is often impractical in dynamic operational environments. Digital twin and transfer learning technologies offer a new approach for intelligent fault diagnosis, addressing these limitations. This paper combines model knowledge and data-driven approaches using digital twin and transfer learning for bearing fault diagnosis. First, a dynamic twin model of the bearing is developed using MATLAB/Simulink (R2018a), simulating fault data under various operating conditions that are difficult to obtain in real-world scenarios. A multi-level construal neural network algorithm is then proposed to minimize cumulative errors in data preprocessing. The digital twin technology generates a balanced dataset for pre-training the model, which is subsequently applied to real-time fault diagnosis in industrial robot bearings via transfer learning, bridging the gap between virtual and physical entities. Experimental results demonstrate the feasibility of the method, with a diagnostic accuracy of 96.95%, marking a 15% improvement over traditional convolutional neural network methods without digital twin enhancement.
