Abstract: Physical infrastructure systems supply crucial resources to residential, commercial, and industrial activities. These infrastructure systems generally consist of multiple types of infrastructure assets that are interdependent. In the event of a disaster, some of the infrastructure assets can be damaged and disabled, creating failures that propagate to other assets that depend on the disabled assets and cause a cascade of failures that may lead to a potential system collapse. We present a bilevel interdiction model in this paper to study this problem of cascading failures in a system of interdependent infrastructure systems with a nondeterministic dependency graph. We also propose a computationally tractable reformulation of the proposed bilevel model and utilize a Benders-type decomposition algorithm to solve the resulting formulation. Computational experiments are performed using infrastructure networks generated from anonymized real-world data to validate the performance of this algorithm.
