After a disruption in an interconnected set of systems, it is necessary to restore service. This requires the determination of the tasks that need to be undertaken to restore service, and then scheduling those tasks using the available resources. This paper discusses combining mathematical programming and constraint programming into multiple objective(More)
Modern society depends on the operations of civil infrastructure systems, such as transportation, energy, telecommunications and water. These systems have become so interconnected, one relying on another, that disruption of one may lead to disruptions in all. The approach taken in this research is to model these systems by explicitly identifying these(More)
Critical infrastructure systems provide services that are essential to both the economy and wellbeing of nations and their citizens. As documented in a recent report to the U.S. Congress (U.S. General Accounting Office, 2001), it is of vital importance that these services not be degraded, whether by willful acts such as terrorism or by natural or random(More)
Recent events have heightened our awareness of the vulnerability of civil infrastructure systems. Most of the research on this topic focused on individual systems, while more recent efforts have recognized the interconnectedness of systems. Infrastructure systems have become so highly interconnected that a failure in one system can propagate through many(More)

This paper applies a geospatial network optimization model to explore environmental, economic, and time-of-delivery tradeoffs associated with the application of marine vessels as substitutes for heavy-duty trucks operating in the Great Lakes region. The geospatial model integrates U.S. and Canadian highway, rail, and waterway networks to create an(More)
The goal of our effort is to eliminate or reduce the impact of a disruption to our critical infrastructures by protecting the quality of the services they provide. Decision technology supports those responsible for achieving this by: • Quantifying the degradation of services provided by all the systems when one or more component of any system is damaged or(More)
Modern society depends on the operations of civil infrastructure systems, such as transportation, energy, telecommunications and water. Clearly, disruption of any of these systems would present a significant detriment to daily living. However, these systems have become so interconnected, one relying on another, that disruption of one may lead to disruptions(More)
