Homeland security analysis focuses on modeling the functional characteristics of critical infrastructure value chains, especially during extreme events. Value chain modeling captures industry behaviors at the systems level between individual firms and national sectors. This approach allows analysis of resilience, consequences, and policy impacts, requiring collaboration with private industry to validate models and develop mutually beneficial policies.

Editor's Notes
- Simulations were conducted of the intra-and inter-firm economic impacts to 3,300 chlorine-related firms of disruptions to chlorine rail transport. After a disruption, larger firms are affected more than small, and regional market power for sellers is large, creating strong competition between buyers. A potential management-based policy of optionally expediting rail cars would decrease in-transit inventories of chlorine by 40%, significantly reducing the potential of chlorine railcars being used as weapons of mass destruction.
