This thesis develops an Operatorâ s Model that mimics the real-world behavior of coal transport in the Port of
Pittsburgh and allows for systematic investigation of â what ifâ disruption scenarios. We model the multi-modal flow
of coal using a network of nodes and arcs representing river transport, with support from a surrounding system of rail
lines and roads. Each mode of shipment has finite capacities with varying costs. Our model routes flows in order to
satisfy contracted supplies and demands at minimum transportation cost. We use 2009 coal shipment data provided by
the United States Army Corps of Engineers to drive delivery patterns. We focus our attention on the Monongahela
River, which carries a significant amount of coal through our system. We employ Defender-Attacker-Defender
techniques to assess critical infrastructure in the context of an intelligent adversary, such as a terrorist, who seeks to
damage the system so as to maximally increase its operating cost. This allows us to assess the relative importance of
critical system components in order to help the United Stated Coast Guard identify where to focus their attention.http://archive.org/details/defendingpittsbu109457296Captain, United States Marine Corp
