近年来,由于气候变化,大规模野火的频率和强度显著增加,成为一种重要的自然威胁。因此,设计能够抵御此类灾害的韧性景观变得至关重要。现有的方法如混合整数规划、随机优化和网络理论虽然有效,但计算需求高,限制了其适用性。为此,本文提出利用深度强化学习技术解决防火隔离带布局的复杂问题。我们采用基于价值函数的方法,如深度Q学习、双重深度Q学习和对抗双重深度Q学习,结合Cell2Fire火灾传播模拟器和卷积神经网络,成功实现了一个能够学习森林环境中防火隔离带位置的计算代理,并取得了良好的结果。此外,我们引入了预训练循环,使代理最初模仿启发式算法,发现其性能始终优于这些解决方案。我们的研究表明,深度强化学习在火灾预防和景观管理中的巨大潜力。

📄 摘要(原文)
Over the past decades, the increase in both frequency and intensity of large-scale wildfires due to climate change has emerged as a significant natural threat. The pressing need to design resilient landscapes capable of withstanding such disasters has become paramount, requiring the development of advanced decision-support tools. Existing methodologies, including Mixed Integer Programming, Stochastic Optimization, and Network Theory, have proven effective but are hindered by computational demands, limiting their applicability. In response to this challenge, we propose using artificial intelligence techniques, specifically Deep Reinforcement Learning, to address the complex problem of firebreak placement in the landscape. We employ value-function based approaches like Deep Q-Learning, Double Deep Q-Learning, and Dueling Double Deep Q-Learning. Utilizing the Cell2Fire fire spread simulator combined with Convolutional Neural Networks, we have successfully implemented a computational agent capable of learning firebreak locations within a forest environment, achieving good results. Furthermore, we incorporate a pre-training loop, initially teaching our agent to mimic a heuristic-based algorithm and observe that it consistently exceeds the performance of these solutions. Our findings underscore the immense potential of Deep Reinforcement Learning for operational research challenges, especially in fire prevention. Our approach demonstrates convergence with highly favorable results in problem instances as large as 40 x 40 cells, marking a significant milestone in applying Reinforcement Learning to this critical issue. To the best of our knowledge, this study represents a pioneering effort in using Reinforcement Learning to address the aforementioned problem, offering promising perspectives in fire prevention and landscape management
