Abstract
This paper presents two important interoperability issues for computer-generated forces. The first is
fundamental and concerns the inconsistent representation of interfiring times of direct-fire weapons in ground combat
in entity-level (i.e. discrete-event) and aggregated-force (with attrition modeled by Lanchester-type equations) combat
simulations. The second is behavioral and again concerns inconsistent representation of platform-level command and
control in such combat in entity-level and aggregated-force simulations. This second inconsistency concerns combatsystem
behavior in acquiring and attacking (i.e. firing at) enemy systems, i.e. whether or not new targets can be
acquired while an enemy target is being engaged. Computational evidence of the seriousness of the consequences of
such inconsistencies on simulation output is presented. This paper shows how they can be avoided by appropriate
mathematical modeling of Lanchester attrition-rate coefficients in aggregated-force combat simulations. Without such
modeling, however, fundamental inconsistencies (with significant consequences) currently exist between all entity-level
and aggregated-force combat simulations.
