This study focused on the resilience evaluation and prediction of URN. A time-varying belief Markov-based resilience model was proposed to analyze the Operational Resilience (OR), which integrates link usability and driving efficiency. The OR is then converted to a normalized scale (COR), which is easier for decision-makers to understand. Finally, a case study was conducted to validate the proposed model. The results showed that demand, link capacity, disaster intensity, and road network structure are significant factors affecting the OR of a URN. Within the OR threshold, the recovery time is generally half the response time and is more stable among different links and precipitation intensities. It has been proven to have satisfactory performance in the estimation and prediction of resilience, which can capture the long-term OR of URN and identify key links and regions that require more attention.

The current HI construction methods typically only focus on constant operating conditions (such as speed or load), rendering them ineffective for variable-speed conditions. To address this gap, this paper proposes a HI construction method for machines under time-varying speed conditions based on benchmark transformation neural networks (BTNN). First, the baseline speed range is determined, and the baseline state observations are identified. Then, with the identified baseline observations, a performance degradation model is established via the double exponential function. Next, BTNN is innovatively proposed using the fitted degradation model, the monitoring state, and speed data to adaptively perform the complex nonlinear mapping from non-baseline observations to baseline values, avoiding the problem of selecting different baseline transformation functions. Compared with the HI constructed by a transformation function and the dimensionless HI, the proposed method unifies state observations at various speeds onto the baseline speed through BTNN, enhancing the comprehensive performance of HI. Comparative experiments on the RUL prediction of turbofan engines and wind turbine bearings reveal that the HI extracted by BTNN exhibits stronger prognosis capabilities than other classical and advanced HIs.</div></div>","PeriodicalId":54500,"journal":{"name":"Reliability Engineering & System Safety","volume":"257 ","pages":"Article 110823"},"PeriodicalIF":9.4,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143286448","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}

However, existing studies often assume all attacks coincide, focusing on cascading failures from a single perspective while neglecting specific attack strategies. This study is the first to apply sequential attack strategies to WMNs and conduct a comparative analysis with synchronous strategies. First, we propose a system model for WMNs that incorporates path loss and link capacity, representing real-world scenarios. Secondly, we introduce two novel reliability metrics, transmission reliability and reliability degradation rate, to quantify the impact of attacks. In the final case study, we analyze the effects of synchronous and sequential attack strategies under four node attack rules. Results reveal that sequential attack strategies dynamically identify and exploit critical nodes, causing prolonged degradation of transmission reliability and amplifying cascading failures. Compared to synchronous attack strategies, sequential attack strategies increase the global reliability degradation rate and reliability degradation rate during the attack phase by 28.62 % and 55.36 %, respectively. Therefore, sequential attack strategies should combine these two node attack rules to achieve maximum impact. These findings confirm that the proposed sequential attack strategy effectively disrupts network performance and provides meaningful insights for developing WMN defense strategies.</div></div>","PeriodicalId":54500,"journal":{"name":"Reliability Engineering & System Safety","volume":"257 ","pages":"Article 110832"},"PeriodicalIF":9.4,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143286635","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}

Therefore, this paper focus on the joint optimization problems to minimize the total cost rate considering stochastic maintenance time for components and stochastic lead time for spares. The problem is modeled as a Markov decision process model and solved by an improved reinforcement learning algorithm, i.e., the improved Q-learning algorithm, which converges more quickly and reaches a smaller value of the total cost rate than the traditional Q-learning algorithm.

In this paper, a novel hybrid method combining the probability density evolution method (PDEM) with an improved Bayesian optimization (BO) deep learning model (IDLM) is proposed for the efficient stochastic vibration analysis of uncertain TTB systems. This approach facilitates information exchange between the train-bridge model and the deep learning model. In this approach, PDEM is integrated into the deep learning framework to achieve a cohesive integration of physical and numerical models. The applicability of the PDEM-IDLM method is verified by comparing the predicted stochastic responses with the results of a validated train-bridge model.
