However, existing model formulations often oversimplify this impact, inadequately representing the intrinsically non-linear and phase-dependent behavior of the carbonation process. In this paper, we propose a novel framework that integrates Physics-Informed Neural Networks (PINNs) and a Predictive Markov Decision Process with Phase-type Approximation (PMDP-PH), enabling resilient and cost-effective infrastructure maintenance under carbonation risks. PINNs embed governing physical laws within neural architectures, enabling accurate inference of carbonation dynamics even under limited observational data. This framework accommodates non-exponential sojourn time distributions in both the initiation and propagation phases, effectively approximated using hypo-exponential models. The PMDP-PH adaptively updates inspection and maintenance strategies by continuously refining the remaining useful life (RUL) distribution in real time. This decision-making process is formulated as a tractable multi-stage model predictive control (MPC) problem over selected belief states, ensuring a non-decreasing value function throughout the robust horizon. Applied to a representative infrastructure system, our method reduces total maintenance costs by up to 61.9% compared to benchmark strategies under variable deterioration scenarios. These findings highlight the promise of combining physics-informed learning with a new form of predictive control strategy to strengthen infrastructure resilience under the growing threat of carbonation-induced deterioration.</div></div>","PeriodicalId":54500,"journal":{"name":"Reliability Engineering & System Safety","volume":"266 ","pages":"Article 111761"},"PeriodicalIF":11.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145221132","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}

The outcrossing rate method has been introduced for TSR analysis, while its extension to multi-component systems suffers from exponential growth in the number of sub-events and high-dimensional computations. To address these challenges, a dimensional reduction outcrossing rate (DRO) method is proposed for efficient TSR analysis of both series and parallel systems. To address the challenge induced by the multiple outcrossing events, a theoretical model for the outcrossing rate is proposed, expressed in terms of two sub-events. An efficient numerical method is developed to compute the probability of these two events. Specifically, the instantaneous reliability indices and the correlation matrix of all component failure events are evaluated in a reduced-dimensional random space, which further improve the efficiency. Additionally, the failure probability, defined by a multiple integral, is computed using a dimensional reduction technique.

To simulate disruption propagation and recovery, we develop a cascading failure model driven by underload mechanisms and incorporate node-level recovery dynamics. Furthermore, we introduce a time-dependent resilience metric based on node reachability over adjustable time windows, enabling a granular assessment of network functionality restoration. Through simulations on both synthetic TSCNs and empirical data from the temporal global wheat trade network, we evaluate resilience under random and targeted disruptions. Our findings reveal that resilience is governed not only by static topology but also by the evolving interplay of node capacities, load distributions, and recovery potentials.

Two main challenges are identified: (i) the need for numerous forward model evaluations during posterior sampling, and (ii) the exploration of the high-dimensional parameter space. To address the first challenge, a probabilistic surrogate model based on polynomial chaos expansions (PCE) is proposed. However, PCE for high-dimensional parameter spaces faces difficulties in robust uncertainty quantification. Although basis adaptation in PCE is promising for low-dimensional QoIs, it struggles with high-dimensional output fields and convergence issues. Additionally, modeling errors introduce further uncertainties.</div><div>To overcome these challenges, an integrated approach employing dimension reduction techniques for both the QoI and parameter space is introduced. For the QoI, a truncated Karhunen-Loève expansion (KLE) is used, and for the parameter space, basis adaptation with convergence acceleration algorithms is applied. This results in a surrogate model that replaces the physical model, significantly improving computational efficiency. To account for uncertainties due to modeling errors, a nonparametric stochastic approach is incorporated into the surrogate model. For the second challenge in Bayesian inference, a block-update Markov Chain Monte Carlo (MCMC) algorithm is applied to promote mixingand enhance the acceptance rate of posterior sampling. The effectiveness of the methods is validated through detailed cases of boiling water reactor spent nuclear fuel assemblies and fully-loaded spent nuclear fuel canisters, demonstrating the applicability and efficiency of the integrated surrogate modeling and block-update MCMC for high-dimensional problems.</div></div>","PeriodicalId":54500,"journal":{"name":"Reliability Engineering & System Safety","volume":"266 ","pages":"Article 111764"},"PeriodicalIF":11.0,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145267742","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}

We introduce a dependence-aware probabilistic framework that explicitly models statistical dependence among SCV compromises via copula-based joint distributions, and incorporates various AVM placement policies (random, hash, affinity). We analyze how SCV dependence structure, the number of attacker accounts, and IDS detection sensitivity affect the overall corruption probability. The risk model is further embedded in a Stackelberg game between defender and attacker, incorporating budget and risk-cap constraints and various detection cost regimes. We prove equilibrium existence and compute optimal strategies via a Monte Carlo procedure. It is discovered that dependence significantly increases the risk of corruption. The probability of corruption can increase by up to 75% compared to the independence baseline, with non-overlapping confidence intervals across different copula families and placement policies.

In the model, the station carrying capacity is calculated based on system balance and evolves through congestion spreading, line perturbation, and line interaction, realizing the full coupling of stations on metro line. The passenger behaviour is considered by an impedance function combined with station state and traffic condition. Nanjing metro is studied. The results reveal a multi-point synchronous congestion extension mode of the network under line perturbation and interaction. Moreover, larger line perturbation and interaction can lead to faster congestion spreading and a larger decline of the network reliability, but the congestion risk can gradually decrease with the increase of hops along lines. High station tolerance, turn back mode, and train frequency adjustment of transfer lines and segment lines are beneficial to the network reliability. The optimal train frequency adjustments of transfer lines and segment lines are also obtained by limiting congestion spreading.
