This study introduces a prognostic model that quantifies infrastructure degradation in highway systems, incorporating the impacts of climate change using an advanced Markovian framework. By assimilating extensive historical maintenance records and detailed climatic data, the model employs a multi-tiered exponential erosion risk framework to enhance predictive accuracy. Our findings indicate a 15-20% acceleration in degradation rates under projected climate scenarios, emphasizing the necessity for climate-adaptive infrastructure management strategies. Utilizing maximal likelihood estimation, the model corrects sample distortion biases, resulting in a 30% improvement in the accuracy of degradation forecasts compared to conventional models. This accuracy enables maintenance cost savings of up to 25% by optimizing repair timings, thus avoiding premature interventions and reducing costs associated with reactive maintenance strategies. The validated model provides a robust tool for strategic planning and adaptive maintenance of highway systems, promoting resilient infrastructure management in the face of evolving climatic conditions. This research ensures that infrastructure professionals can anticipate and mitigate the impacts of climate change, optimizing maintenance budgets and extending the service life of highway assets.
本研究引入了一个预后模型,该模型使用先进的马尔可夫框架量化了公路系统基础设施的退化程度,纳入了气候变化的影响。通过综合广泛的历史维护记录和详细的气候数据,该模型采用多层次指数侵蚀风险框架来提高预测精度。我们的研究结果表明,在预测的气候情景下,退化速度会加速 15-20%,这强调了需要采取适应气候变化的基础设施管理策略。该模型利用最大似然估计法校正了样本失真偏差,与传统模型相比,退化预测的准确性提高了 30%。通过优化修复时机,这一准确性可以节省高达 25%的维护成本,从而避免过早干预和减少与被动维护策略相关的成本。验证后的模型为公路系统的战略规划和自适应维护提供了一个强大的工具,促进了在不断变化的气候条件下具有弹性的基础设施管理。本研究确保基础设施专业人员能够预测和减轻气候变化的影响,优化维护预算并延长公路资产的使用寿命。
