CIMAP : Role and Structure The CIMAP approach to addressing Virginia's critical infrastructures is based on a bottom-up approach incorporating three main elements. These elements, which are increasingly hierarchical, include (1) an analysis of changing demands on individual infrastructures, (2)an examination of how these demands are leading to greater infrastructure interdependencies, and (3) a determination of how the demands and interdependencies affect their individual and collective capability and availability. The basic protocol also will incorporate a three step approach: the identification and definition of issues; the analysis and modeling of solution alternatives; and solution development, demonstration, and policy support. In order to ensure the success of the approach CIMAP will use a variety of tools designed to address the technical, policy and public aspects of critical infrastructure interdependency. These include background research, outreach workshops, and technical presentations. The research activities, which will be supported by Virginia Tech graduate research assistants, will be undertaken primarily to provide the technical underpinning for the modeling efforts. The outreach workshops will be directed at major stakeholder groups in Virginia, and will focus on evaluating and clarifying the implications of technical findings in the policy arena. The technical presentations, including web-based and live presentations in public venues, will transcribe technical and policy issues to broader audiences with an interest in Virginia's development future.
