Abstract
En 中文
Urban critical infrastructure systems serve as lifelines for modern society, yet their vulnerability to deliberate attacks underscores the urgency of enhancing resilience. Although extensive research has focused on pre-allocating resources against external threats, a key gap persists: the lack of a unified framework that simultaneously addresses external attacks and internal cascading failures under resource constraints. To address this, we propose a novel tri-level dynamic game-theoretic framework integrating defense resource deployment, attack path prediction with cascading effects, and recovery strategy optimization. A nested heuristic algorithm is developed to validate the model and algorithm’s effectiveness.
