To scientifically assess urban transportation safety resilience (UTSR<span><span><sup>1</sup></span></span>) and its evolutionary process under extreme rainstorm disasters, this study proposes a novel assessment method by modeling the UTSR using the catastrophe theory approach. First, a safety framework for the urban transportation system is constructed, and catastrophe theory is applied to analyze catastrophic effects on the system. Second, factors affecting UTSR are identified, and their relationships are analyzed using a stock and flow model. Finally, the effectiveness of the UTSR dynamic simulation model is analyzed using the case study of an extreme rainstorm event in Xi'an, China.

This study employs deep learning techniques to enable efficient prediction and assessment of damage states in-service RC bridge piers subjected to seismic events. To support model training, a parametric sample set of 100 bridge piers is generated using Latin Hypercube Sampling, leading to the development of a comprehensive seismic response database containing 66,000 samples across 15 defined damage states. These databases account for inherent seismic randomness, complex failure modes, and time-dependent composite evaluation indicators. A novel deep learning framework, CC-ViT, based on the Vision Transformer architecture, is proposed. This framework integrates Continuous Wavelet Transform, Context Anchored Attention, and DropKey techniques to enhance feature extraction and model generalization. Multiple models are trained and evaluated in a supervised learning setting. Comparative analysis reveals that CC-ViT achieved the highest test accuracy at 85 %. Grad-CAM-based interpretability analysis further confirms that CC-ViT effectively captures critical regions in the seismic response spectrum, supporting informed and explainable decision-making.

Firstly, by transforming time-variant multiple responses to time-invariant extreme values, an eXtreme multi-domain transformation concept is presented, to establish the time-invariant multi-input multi-output (TiMIMO) dataset; moreover, by embedding physics/mathematics knowledge into multi-objective ensemble modeling, a physics-embedding multi-response regressor is proposed, to synchronously construct the surrogate model for highly complex multiple output responses.

Nevertheless, precise forecasting of warranty claims is challenging due to the data maturation phenomenon, which is characterized by challenges that include market demand variability, reporting delays, heterogeneous production quality, and customer late claim rush. This paper proposes the Deep auto-encoded Conditional Gaussian Mixture Model (DCGMM) for warranty claims forecasting. DCGMM is a novel hybrid Bayesian and deep learning framework. The method learns a prior joint distribution between auto-encoded temporal latent embeddings extracted from early observed cumulative warranty claims and long-term mature warranty claims based on historical products. DCGMM then uses Bayesian inference to forecast the mature warranty claims of an in-service product of interest conditioned on its auto-encoded embeddings extracted from its limited early claims observations. DCGMM is robust to product variability and complex temporal trends because of its ability to identify different cluster or sub-population behaviors. Furthermore, learning a lower-dimensional space is essential to achieving tractable Bayesian inferences. We validate the performance of the DCGMM for warranty claims forecasting on a large-scale automotive case study and compare it to other state-of-the-art time-series forecasting algorithms.</div></div>","PeriodicalId":54500,"journal":{"name":"Reliability Engineering & System Safety","volume":"263 ","pages":"Article 111230"},"PeriodicalIF":9.4,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
