This model informs analyses of the availability of transportation fuel in the event the fuel supply chain is disrupted. The portion of the fuel supply system represented by the network model (see figure) spans from oil fields to fuel distribution terminals. Different components of this system (e.g., crude oil import terminals, refineries,...
NISAC has developed a range of capabilities for analyzing the consequences of disruptions to the chemical manufacturing industry. Each capability provides a different but complementary perspective on the questions of interest—questions like Given an event, will the entire chemical sector be impacted or just parts? Which chemicals, plants,...
CASoS are vastly complex physical-socio-technical systems. Examples include: tropical rain forests, agro-eco systems, cities, infrastructure, governments, political systems, education systems, health care systems, financial systems, economic systems, the global energy system, and global climate. We must understand the workings, relationships,...
NISAC has developed N-ABLE™ to assist federal decision makers in improving the security and resilience of the U.S. economy. N-ABLE™ is a large-scale microeconomic simulation tool that models the complex supply-chain, spatial market dynamics, and critical-infrastructure interdependencies of businesses in the U.S. economy. N-ABLE has...
The National Infrastructure Simulation and Analysis Center (NISAC) is a modeling, simulation, and analysis program within the Department of Homeland Security (DHS) comprising personnel in the Washington, D.C. area, as well as from Sandia National Laboratories (SNL) and Los Alamos National Laboratory (LANL). Congress mandated that NISAC serve as a “source of national expertise to address critical infrastructure protection” research and analysis. 
NISAC prepares and shares analyses of critical infrastructure, including their interdependencies, vulnerabilities, consequences, and other complexities, under the direction of the Office of Infrastructure Protection (IP), Infrastructure Analysis and Strategy Division (IASD). To ensure consistency with IP priorities, NISAC initiatives and tasking requests are coordinated through the NISAC program office.
NISAC provides strategic, multidisciplinary analyses of interdependencies and the consequences of infrastructure disruptions across all 16 critical infrastructure sectors at national, regional, and local levels. NISAC experts have developed and are employing tools to address the complexities of interdependent national infrastructure, including process-based systems dynamics models, mathematical network optimization models, physics-based models of existing infrastructure, and high-fidelity agent-based simulations of systems.
