Synopses of NISAC Modeling Capabilities
- Dynamic Infrastructure Interdependencies Simulation & Analysis (DIISA) System dynamics modeling to quantify and evaluate the effects of infrastructure operations, ability to meet demand given disruptions, changing conditions (e.g., sudden changes in demand, time of day, time of year, unusual event, new regulations, incentives, market structures) s and their interdependencies dependence on each other.
- NISAC Agent-Based Laboratory for Economics (N-ABLE) A large-scale microeconomic simulation tool that captures complex supply chain and market dynamics of businesses in the U.S. economy for a better understanding of the impacts of vulnerabilities and disruptions on national economic security and continuity.
- Chemical Sector Analysis Capability This analysis capability leverages core NISAC data management and modeling/simulation expertise to understand the complex infrastructure dependencies and interdependencies inherent in this sector utilizing perspectives ranging from national down to the individual asset level.
- Network Optimization Models (RNAS and ATOM) Representation of infrastructures using network models comprised of interconnected nodes and links provides a means for estimating network capacities under normal and disrupted conditions. Mathematically sound non-linear optimization techniques can then be applied to these networks to understand their behavior the best-case operation levels under the specified system conditions.
- Analysis for National Priorities: Tiers 1 and 2 Supporting DHS' efforts to identify assets most essential to national well-being, NISAC analyzes the nation’s assets for significant impacts within and across infrastructure sectors, including consequences to public health and safety as well as direct and cascading costs to the national economy.
- Advanced Modeling & Techniques Investigation (AMTI) This team identifies and evaluates new theories, methods and analytical tools that are useful for understanding the structure, function, and evolution of complex interdependent critical infrastructures. AMTI has developed the Loki toolkit for simulating abstract, complex adaptive networks.
- Network Simulation Modeling Analysis Research Tools (N-SMART) These tools are comprised of discrete event and/or flow-based models of telecommunications traffic across networks. The network-wide model includes trunks and switch processor resources, network management controls, and customer behavior in a single model.
- Interdependent Energy Infrastructure Simulation System (IEISS) A comprehensive simulation environment for interdependent energy infrastructures representation and analysis (focused especially on electric power and natural gas systems) based on the physical laws and resolved to the infrastructure component level.
- Water Infrastructure Simulation Environment (WISE) An analytic framework supporting the evaluation of public water supply infrastructure in terms of both infrastructure specific and interdependency issues.
- Urban Infrastructure Suite (UIS) A set of seven interoperable modules that employ advanced modeling and simulation methodologies to represent urban infrastructures and populations. These simulation-based modules are linked through a common interface for the flow of information between UIS sector simulations to model urban transportation, telecommunications, public health, energy (IEISS), financial (commodity markets), and water-distribution (WISE) infrastructures and their interdependencies.
