ABSTRACT
From the perspective of an interdependency, a new fragility has entered into the system in that the speed and convenience with which technology is used has reduced the ability to operate without that technology. When modeling potential impacts, the topography of bonds, dependencies, and interdependencies must be understood to effectively map and predict the impacts associated with certain kinds of attacks. An interdependency that links flexible sectors (such as with the commercial and government facilities), however, would be looked at in terms of several other factors—such as whether the issue is transitory or not. The interdependencies linking four sectors are particularly important to note. These stem from the interdependencies between the Energy, Transportation Systems, Communications, and Financial Services Sectors. Businesses continue to focus on the concept of “just in time” delivery, with the premise being that the transportation network replaces the warehousing infrastructure normally used to maintain reserves of inputs.
