Input–Output Models of Infrastructure Systems
Infrastructure systems consisting of mutually interdependent components are common in modern urban settings. Such systems are constantly at risk of cascading failure from various triggering events or perturbations. Consequently, such perturbations cause indirect ripple effects to other interdependent systems, which can propagate through the network as inoperability. Inoperability input–output models are extensions of input–output models that can represent the flow of inoperability through such critical infrastructure systems. Such models are discussed in this chapter, supported by illustrative examples and corresponding LINGO code.
