Performance modeling—the
use of detailed engineering models to simulate and analyze the performance
of one or more components of a system architecture—is used to perform
trade-off studies and "what if?" analyses that result in optimal
design choices and maximum system effectiveness. 
ACS harnesses this powerful M&S technology as a means of improving
system performance and controlling life cycle costs. Our efforts in
this area are ongoing and include the development of tools to streamline
the M&S process; model development, design, and testing; and simulation
setup, execution, and analysis.
ACS currently
supports performance modeling of the Army's Tactical Internet using the
C4I Modeler's Tool Suite,
software tools developed by ACS as part of a Small Business Innovation
Research R&D effort to optimize the setup and post-simulation data
reduction and analysis required for experiments using large-scale C4I
networks. ACS also develops, enhances, and maintains models of the Army's
next-generation C4I systems.
