The Department of Defense proclamation that all simulations comply with High Level Architecture (HLA)
standards prompted the U.S. Army Training and Doctrine Command (TRADOC) Analysis Center (TRAC) to
investigate the feasibility of including Janus in future HLA Federations. One of the Army’s most extensively used
models for training and analysis, Janus is an interactive, six-sided, closed, stochastic high-resolution simulation.
Fielded in 1978, Janus was coded in FORTRAN and, with its numerous revisions and enhancements, represents a
substantial investment for the U.S. Army. As a legacy model coded in a procedural language, there are considerable
challenges for Janus to meet HLA requirements. For example, the notion of an object model definition was not
envisioned during Janus development and is not intrinsic to its world view. In this paper we will describe the
methodology we are using to develop a Simulation Object Model (SOM) of Janus independent of any existing
federation of models. Our experience with this methodology will provide insight into the general problem of
producing an HLA-compliant SOM for a legacy simulation.
