Undersea Weapons (UW) | systems analysis & simulation (sas)

TRM ChartThe Systems Analysis and Simulation (SAS) Division specializes in high-fidelity, physics-based digital modeling and simulation.  SAS has the responsibility for the design, construction, validation, and maintenance of a suite of large-scale undersea warfare simulations used by technology developers, evaluators and fleet trainers.  The Division's technical capabilities include: operations research, systems analysis, game theory, optimization, Analyses of Alternatives (AOAs), Tactical Memo support, and simulation verification, validation, and accreditation (VV&A).  SAS boasts extensive experience in the areas of:  physics-based modeling; undersea systems; RF systems; Monte Carlo simulation; visualization; Matlab® and Simulink®; electricity and magnetism; and graphical user interface (GUI) development.

Expertise resident within the Division represents multiple engineering and scientific disciplines:  electrical engineering, mechanical engineering, acoustics, engineering science and mechanics, computer science, computer engineering, software engineering, biomedical engineering, and material science.  More than half of the Division employees hold advanced degrees.

SAS PhotoComputational facilities include a local area network comprised of over 1000 Linux processors, along with state-of-the-art scientific visualization tools and facilities. The key component in achieving SAS's mission is the selectable-fidelity, physics-based Technology Requirements Model (TRM) simulation package. TRM has found important applications across the entire scope of the defense acquisition management life cycle.  It is used to define requirements for systems; develop concepts; design, develop, and evaluate subsystems; evaluate system-level performance, including support for developmental and operational testing; and to educate and train fleet personnel on undersea system capabilities.

TRM is used by the Naval Undersea Warfare Center (NUWC), Division Newport; Surface Tactical Development Group (STDG); Commander Submarine Development Squadron 12 (CSDS-12); COMSUBPAC Pearl Harbor; Atlantic Undersea Test and Evaluation Center (AUTEC); JHU/APL; Royal Australian Navy / Australian Defence Science and Technology Organisation (DSTO); ArgonST, Inc.; In Depth Engineering, Inc.; and multiple units within the Applied Research Laboratory/Pennsylvania State University.
