Protecting critical infrastructure systems, such as electrical power grids, has become a primary concern for many
governments and organizations across a variety of stakeholder perspectives. Critical infrastructures involve multidimensional,
highly complex collections of technologies, processes, and people, and as such, are vulnerable to
potentially catastrophic failures on many levels. Moreover, cross-infrastructure dependencies can give rise to cascading
effects with escalating impact across multiple infrastructures. Critical infrastructure protection involves both
safeguarding against potential disaster scenarios and effective response in the aftermath of infrastructure failure. Our
research is developing innovative approaches to modeling critical infrastructures in order to support decision-making
during reconstitution efforts in response to infrastructure disruptions. By modeling the impact of infrastructure elements,
both within and across infrastructures, we can recommend focus areas for reconstitution resources across different
stakeholders in the context of their current goals. An interactive geovisualization interface provides a natural context for
this infrastructure analysis support. This paper presents an overview of our approach and the GIS modeling environment
under development for decision support in critical infrastructure reconstitution.
