Systems Modeling


System modeling is the interdisciplinary study of the use of models to conceptualize and construct systems.  A common type of systems modeling is function modeling, with specific techniques such as the functional flow block diagram.  These models can be extended using functional decomposition, and can be linked to requirements models for further systems partition.

Cyber Security Econometrics Systems (CSES)
— To make effective cybersecurity decisions, stakeholders need to assess security countermeasures, architecture, and operations. ORNL researchers invented an improved security metric to support analysis of how well a system meets its security objectives. The technology provides courses of action that have the highest risk reduction return on investment, reducing the most risk for the lowest cost.

Center for Accelerating Material Modeling
— Seed project is a collaboration between the Neutron Sciences Directorate, Computing and Computational Sciences Directorate, and Physical Sciences Directorate. PI is Dr. Mark Hagen and Co-PI is Galen Shipman. Provide a toolkit to integrate materials modeling and simulation with the analysis of experimental data taken at the Spallation Neutron Source.

Facility Vulnerability Using the Visual Interactive Site Analysis Code (VISAC)
— Nuclear, chemical, and other industrial facilities are a large and vital part of the US infrastructure. These facilities not only represent a large financial investment but also can pose a serious risk should they become targets for a terrorist attack. Releases following such an incident can adversely affect the public health and contaminate large areas. It has become clear that these high-value, fixed assets rank near the top among possible targets that must be safeguarded from terrorists.
