However, hardware redundancy significantly increases manufacturing costs and system complexity, while analytical redundancy faces challenges in establishing accurate mathematical models. To address these issues, this paper proposes an information redundancy method for flight data based on sensor-modal fusion. This method leverages deep learning networks to learn the complex coupling relationships between flight parameters from a vast amount of historical flight data. In this respect, a mapping model for flight parameters is established to replace traditional mathematical models used for analytical redundancy. First, the traditional sliding window process is improved by proposing a Fibonacci sampling to balance computational resources and historical view length. Next, a sensor-modal fusion-based prediction model is designed to avoid spatial interactions among sensor features during feature extraction. Furthermore, a sensor attention module and a modal attention module is employed to improve the interpretability of the model. Finally, a Lebesgue evaluation metric is introduced to address ineffective assessment under state balance conditions. The proposed method was validated using real flight data. The results demonstrate that the Lebesgue mean absolute error remained below 1.4 %, outperforming all comparative methods and affirming the effectiveness and superiority of the proposed method.

A comprehensive vulnerability assessment model is then built, considering both structural and functional aspects. Finally, a case study is conducted to assess the power network's vulnerability under various demand settings and failure scenarios. The case study reveals that node failures affect not only neighboring nodes but also non-adjacent ones. Also, structural vulnerability (SV) and functional vulnerability (FV) reflect different aspects of power network performance, and SV is generally higher than FV. As expected, both SV and FV are found to increase with rising demand, and the vulnerability growth trends vary across different demand growth scenarios. Based on the influence of demand growth on system vulnerability, power network nodes are categorized into three types: inherently vulnerable, demand-sensitive and stable.

Moreover, the interactive degradation between the upstream and downstream machines, caused by the product quality deviations, changes with the different production routes for the variable product types. These factors, combined with the uncertain production schedules, present significant challenges for effective maintenance scheduling. To address these challenges, the maintenance scheduling problem is modeled as a Hidden-Mode Markov Decision Process (HM-MDP), where product types are treated as hidden modes that influence machine degradation and the subsequent maintenance decisions. The Interactive Degradation-Aware Proximal Policy Optimization (IDAPPO) reinforcement learning framework is introduced, enhancing the PPO algorithm with Graph Neural Networks (GNNs) to capture interactive degradation among machines and Long Short-Term Memory (LSTM) networks to handle temporal variations in production schedules. An entropy-based exploration strategy further manages the uncertainty of production schedules, enabling IDAPPO to adaptively optimize maintenance actions. Extensive experiments on both small-scale (5-machine) and large-scale (24-machine) systems demonstrate significantly reduced system losses and accelerated convergence of IDAPPO compared to the baseline approaches.

Nevertheless, their achievements completely rely on the availability of target domain samples during training. Unfortunately, these testing samples are usually unavailable in advance due to routine maintenance and long designed life. Towards the real-time diagnosis demands in actual engineering, this study proposes a decision margin-based domain generalization framework that can indirectly achieve the distribution alignment between source and unseen target domains. Based on the framework, a novel DG-Softmax loss considering the class-level decision margin is proposed to enhance the feature separability. A novel adaptive and anti-interference selection mechanism of class-level decision margin named ACADM mechanism is established to select the decision margin in DG-Softmax loss adaptively. Furthermore, the DG-Softmax model, which only includes a task-related loss without any other auxiliary loss terms, is established to improve the computational efficiency and the diagnosis precision. A two-stage training scheme is utilized, including pre-training and training phases. The proposed DG-Softmax is evaluated on two cross-bearing transfer tasks from laboratory bearing to actual wind-turbine bearing and six cross-speed transfer tasks of the system-level planetary gearbox, and the experimental results validate that it outperforms other typical methods.

To address these concerns, a novel dynamic HI that considers HI-level temporal dependence is constructed through an unsupervised framework. Specifically, a degradation feature learning module composed of a skip-connection-based autoencoder first maps raw signals to a representative degradation feature space (DFS) to automatically extract essential degradation features without the need for expert knowledge. Subsequently, in this DFS, a new HI-generating module embedded with an inner HI-prediction block is proposed for dynamic HI construction, where the temporal dependence between past and current HI states is guaranteed and modeled explicitly. On this basis, the dynamic HI captures the inherent dynamic contents of the degradation process, ensuring its effectiveness for degradation tendency modeling and future degradation prognostics.
