Undersea Weapons >  Systems Analysis & Simulation (SAS)

The mission of Systems Analysis and Simulation (SAS) is to support ARL and its sponsors by developing a full range of simulation, analysis, and visualization capabilities that can be used to define requirements; develop concepts; design, develop, and evaluate subsystems; evaluate system-level performance; and educate fleet personnel on torpedo capabilities.

The SAS division specializes in high-fidelity digital modeling and simulation, with emphasis on undersea applications, with a key player being the Technology Requirements Model (TRM). The SAS division has the responsibility for the design, construction, validation, and maintenance of the large-scale undersea warfare simulations used by developers and evaluators of individual technologies, subsystems, and entire systems. Further pages of this Website provide information on TRM Simulation Components and SAS Computation capabilities.

The simulations developed by SAS cover a wide range of complexity, ranging from evaluation of simple concepts to performance evaluation of large-scale system simulations in multi-object underwater scenarios. The simulations are built using a common, formalized simulation architecture and drawing from an extensive digital simulation library. Rigorous configuration management procedures are followed in all model development and maintenance. The range of simulations includes:

  • Synthetic environments / environmental servers and models.
  • Signal processing models.
  • Vehicle control and dynamics models.
  • Notional systems / concept assessment models.
  • Large-scale digital simulations of underwater systems and scenarios.

The simulation architecture serves as a seamless means of providing requisite fidelity balanced against throughput adaptability for a broad range of undersea warfare applications. The simulations can be composed to span applications from concept assessment to point design to technology development to acquisition support, with the ability to increase the level of fidelity of the desired models at any stage in the process.

The SAS division's scientific analysis capabilities include: operations research, systems analysis, game theory, optimization, Analyses of Alternatives (AOAs), Military Value Assessments (MAVs), and simulation Verification, Validation, and Accreditation (VV&A).
